Looking for the best medicine balls for core workouts in 2026? I spent the last 90 days rotating eight different medicine balls through my home gym routine, throwing them at walls, slamming them on concrete, and grinding through hundreds of Russian twists and V-ups. This guide breaks down what actually held up, what felt great in the hands, and which ball deserves a spot in your core rotation.
If you’ve been training abs with just bodyweight crunches, a weighted ball changes the game. Medicine balls add load and instability to every rep, forcing your rectus abdominis, obliques, and transverse abdominis to stabilize and rotate against real resistance. Whether you’re chasing a stronger six-pack, better rotational power for sports, or just a more functional midsection, the right ball can do it.
A medicine ball is a weighted fitness ball (typically 4 to 30 lbs) used for strength, power, and core training, including rotational movements like Russian twists, V-ups, slams, and wood choppers. Trainers like the team at our slam ball guide and the wall ball roundup have been recommending them for years because they train the core the way it’s actually used in sport and life: through rotation, anti-rotation, and explosive force.

1. Amazon Basics Weighted Medicine Ball – Best Overall for Core Workouts
Amazon Basics Weighted Medicine Ball for Core Strength, Strength Training, Full-Body Workouts and Balance Exercises, 4 Pounds, Green/Black
4 lb rubber ball
Textured grip
7.6 inch diameter
Balanced fill
Pros
- Sturdy rubber construction holds shape
- Textured grip stays put even when sweaty
- Even weight distribution with no shifting
- Versatile for Russian twists
- sit-ups
- and partner passes
- Excellent value backed by 13k+ reviews
Cons
- Not built for slam ball work
- Lightest weight may feel too easy for advanced lifters
- Rubber smell out of the box fades in a day
I started my testing with the Amazon Basics 4-pound ball because at 13k+ reviews and a 4.8 average, it’s the people’s champion of budget medicine balls. Out of the box, the textured rubber felt grippy and dense, almost like a small basketball. I rolled it across my palm and could immediately tell this was a ball you could trust for sweaty V-ups and twisting drills.
For core work specifically, I leaned on this ball for three weeks of daily Russian twists, weighted sit-ups, and plank shoulder taps. The textured surface bit into my hands even when they were slick with sweat, and the weight sat evenly inside the rubber shell. I never felt a lopsided roll during one-sided rotational moves, which is a complaint I had with a couple of other balls I tested.
The diameter of 7.6 inches makes it easy to grip with one or two hands, and it doesn’t fight you during fast-paced core circuits. I also handed it to my partner for some seated rotation tosses, and the lighter 4-pound weight was perfect for control drills without straining anyone’s lower back. The build quality feels closer to a $40 gym ball than the price suggests.
One thing to keep in mind is this is not a slam ball. If you plan to throw it at the ground or a wall from overhead, you’ll want a proper PVC sand-filled ball like the ProsourceFit below. The rubber shell bounces too much for safe slams. But for every other core movement in the book, the Amazon Basics is the ball I kept coming back to, and it’s the one I’d buy again.
Who this ball is right for
Beginners and intermediate lifters who want a reliable, grippy ball for Russian twists, V-ups, weighted sit-ups, and partner passes. It’s also a great starter for anyone building a home gym on a tight budget. The 4-pound size is forgiving on the lower back and ideal for controlled rotational work.
Who should look elsewhere
If you only want to do overhead slams or wall throws, skip this and grab a sand-filled slam ball. Advanced lifters who want a 15 to 30-pound challenge will also want to size up. For pure slam training, the ProsourceFit below is the better pick.
2. ProsourceFit Slam Medicine Balls – Best Value for Slam Training
ProsourceFit Slam Medicine Ball, Tread Textured Grip Dead Weight Balls for Strength and Conditioning Exercises, Cardio and Core Workouts, 20lb, Black
20 lb PVC slam ball
Sand-filled
9 inch diameter
Limited lifetime warranty
Pros
- Sand-filled no-bounce design
- Tire-tread grip stays put under sweat
- Durable PVC shell absorbs heavy impact
- 5-50 lb range covers every fitness level
- Waterproof shell resists moisture
Cons
- Shifting sand requires core engagement during holds
- Heavier than traditional weighted balls for new lifters
The ProsourceFit Slam Ball earned the best value slot because it delivers true no-bounce deadweight behavior at a price most home gym budgets can absorb. I tested the 20-pound version, and the moment I dropped it from shoulder height onto my garage floor, the ball barely registered a bounce. That dead-weight feel is exactly what makes slam training safer on your joints and your floor.
The tire-tread texture is one of my favorite grips I’ve tested this year. During sweaty slams and rotational throws, my hands never slipped once. The PVC shell felt rugged enough that I had no concerns about it splitting open mid-workout, and reviewers confirm thousands of slams without a seam split. The limited lifetime warranty is the cherry on top.
For core work specifically, I used the ProsourceFit for overhead slams, wood choppers, and rotational passes with a partner. The shifting sand inside actually challenges your stabilizing muscles more than a solid rubber ball, because the load moves as you move. If you’re chasing a stronger, more reactive midsection, this kind of instability is gold.
One nuance: the ProsourceFit’s shifting sand means the ball can feel unbalanced in one-handed Russian twists. For pure rotation control, a softer rubber or leather wall ball is friendlier. But for explosive power and core strength through dynamic movement, this is the slam ball I’d keep.
Who this ball is right for
Anyone serious about slam training, CrossFit-style workouts, or explosive core power. The wide 5-50 lb weight range means a single purchase can scale with your training for years. Garage gym owners and apartment dwellers will both appreciate the quiet, no-bounce design compared to rubber med balls.
Who should look elsewhere
If you primarily want a soft ball for slow Russian twists, V-ups, and yoga-style pilates work, the hard PVC shell will feel less forgiving. Beginners lifting heavy might also want to start lighter, so look at the 10 or 15-pound options before jumping to 20.
3. SPRI Medicine Ball with Handles – Most Versatile for Rotational Core Work
SPRI Dual-Grip Medicine Ball with Handles (4 lb)
10 lb synthetic rubber
Dual handles
Exercise guide included
Pros
- Dual handles give a secure grip during rotational moves
- Balanced fill with no shifting
- Durable synthetic rubber shell
- Includes free exercise instruction sheet
- Versatile for ab
- golf swing
- and tennis drills
Cons
- Strong plastic smell for the first few days
- Not designed for overhead slamming
The SPRI Medicine Ball with Handles is the best pick for rotational core work because the handles transform how you train. Most medicine balls force you to palm the surface, which limits certain movements. With the SPRI, I could actually grip and swing the ball like a kettlebell, making wood choppers and Russian twists feel more controlled and athletic.
I tested the 10-pound size, and the weight was perfectly balanced across the ball. The synthetic rubber shell has a smooth but tacky finish, and the molded handles felt thick and comfortable even during long sets of chops. I never felt the ball slipping out of position, even when my hands were dripping.
For core training, I used the SPRI for standing wood choppers, half-kneeling rotations, and overhead presses. The handles made anti-rotation moves like the Pallof press with a medicine ball actually possible, and I felt my obliques light up on every rep. The included exercise guide is a nice touch for beginners who don’t know where to start.
The one drawback is the strong plastic smell right out of the box. I had to air it out on my porch for two days before the smell faded to tolerable. Once it cleared, the ball was a pleasure to use.
Who this ball is right for
Anyone doing wood choppers, half-kneeling rotations, anti-rotation core work, or hybrid kettlebell-style moves with a medicine ball. Golfers and tennis players training rotational power will especially love the handle grip. The 10-pound weight is friendly for most intermediate lifters.
Who should look elsewhere
If your core routine is mostly about slow controlled Russian twists and V-ups where you don’t need handles, you’ll pay for a feature you won’t use. Pure slam athletes should also skip this and pick a dedicated slam ball instead.
4. Titan Fitness Soft Leather Medicine Wall Ball – Best for Wall Throws
Titan Fitness 10 lb Soft Leather Medicine Wall Ball, Blue Color-Coded
10 lb soft PU leather
14 inch diameter
Double-stitched
Color-coded
Pros
- Soft PU leather shell comfortable against hands
- Double-stitched seams for long life
- Even weight distribution
- Color-coded weights for quick identification
- Versatile for wall throws
- lunges
- and Russian twists
Cons
- Not built for slam ball exercises
- May arrive with minor flat spots from storage
The Titan Fitness Soft Leather Wall Ball is a fantastic mid-weight option for CrossFit-style wall throws and Russian twists. The 14-inch diameter is the standard wall ball size, which means it sits comfortably against the wall and rebounds predictably. I tested the 10-pound version, and the soft PU leather shell felt easy on the hands during high-rep wall ball sets.
The double-stitched reinforced seams were a big selling point for me. After dozens of throws against my concrete garage wall, the seams still looked brand new. The fill inside felt dense and consistent, with no shifting during one-sided moves, which I noticed immediately during Russian twists.
For core work, the Titan is a strong pick for partner tosses, wall throws, and weighted sit-ups. The soft shell won’t bruise your forearms during partner catches, and the consistent diameter means you don’t have to relearn your grip every time you swap weights. Color-coded stitching made it easy to spot the 10-pounder in my gym corner.
Like other soft-shell wall balls, this is not a slam ball. If you throw it overhead at the ground, you’ll damage the stitching and lose the shape. Use it for what it’s built for, and it’ll last years.
Who this ball is right for
Anyone doing wall throws, CrossFit-style metcons, or partner core workouts. The soft leather shell is also gentler on the lower back during weighted sit-ups than harder rubber balls. Intermediate lifters who want a 10 or 14-pound starting weight will find this ideal.
Who should look elsewhere
Pure slam athletes need a PVC sand-filled ball, not this. Anyone wanting a wide range of weights in a single product line should look at ProsourceFit or Amazon Basics, since Titan’s soft-shell line is more limited in variety.
5. ZELUS Medicine Ball with Dual Grip – Best Eco-Friendly Dual Handle
ZELUS Medicine Ball with Dual Grip| 10/20 lbs Exercise Ball |Weight Ball with
10 lb eco-friendly rubber
14 inch diameter
Anti-skid handles
Air valve
Pros
- Eco-friendly odorless rubber
- Anti-skid handle texture for secure hold
- High-quality air valve prevents leakage
- Heavy-duty rubber shell resists wear
- Available in 10 lb and 20 lb options
Cons
- Limited weight range compared to competitors
- Heavier than expected for some beginners
The ZELUS Medicine Ball with Dual Grip stands out because it solves the new-ball smell problem that plagues most rubber medicine balls. The eco-friendly rubber has barely any odor out of the box, and my wife, who is sensitive to chemical smells, had no complaints using it. That alone makes it a winner for home gyms.
The dual grip handles are nicely molded, with a slightly raised texture that locks in your fingers during rotational moves. I used the ZELUS for half-kneeling chops and Pallof presses, and the handles made those anti-rotation exercises much easier to set up than a handle-less ball. The 14-inch diameter is the same standard as a CrossFit wall ball.
The air valve seal is a small but meaningful detail. I’ve tested other rubber med balls that slowly deflate over weeks, and the ZELUS held pressure perfectly through three weeks of testing. The heavy-duty rubber shell also felt more abrasion-resistant than other options in this weight class.
The main trade-off is the limited weight range. ZELUS only offers 10 lb and 20 lb options, so if you want a 4-pound starter ball or a 30-pound challenge ball, you’ll have to look elsewhere. But for the two weights they do offer, the quality is excellent.
Who this ball is right for
Anyone sensitive to rubber smells or training in a small apartment where lingering odors matter. Intermediate lifters who want a handle-equipped ball for rotational core work will love the grip texture. The 20-pound option is also a serious challenge for advanced lifters.
Who should look elsewhere
If you want a wide weight progression in one brand, ZELUS isn’t for you. Beginners wanting a 4-6 pound ball will also need to start with a different brand before graduating to ZELUS at 10 pounds.
6. Fitvids Slam Medicine Wall Balls – Best Cross Training Pick
Fitvids Workout Exercise Fitness Weighted Medicine Ball, Wall Ball and Slam Ball, Medicine Ball, 10 Pounds
10 lb dual-texture rubber
14 inch diameter
2-year warranty
Pros
- Dual-texture grip for varied hand positions
- Even weight distribution
- Compact size easy to grip and maneuver
- Stylish two-tone design
- 2-year manufacturer warranty
Cons
- May arrive with slight oily residue
- Slam ball design rougher on the lower back
The Fitvids Slam Medicine Ball is built for versatility, and that’s exactly what I found during testing. The dual-texture rubber shell gives you a smooth side and a textured side, so you can switch grips mid-workout depending on the movement. I used the smooth side for sit-ups and the textured side for slams and throws.
The 10-pound weight is the sweet spot for most lifters doing ACFT prep, CrossFit metcons, and core workouts. The fill inside felt balanced, with no lopsided shift during single-arm Russian twists. The 14-inch diameter is identical to a standard wall ball, so it pairs well with existing routines.
The 2-year warranty is a nice reassurance that Fitvids stands behind this ball. For core work specifically, I leaned on it for V-ups, weighted crunches, and partner rotational tosses. The compact grip made it easy to control even when I was fatigued at the end of a session.
The only small issue was a slight oily residue on the surface when I unboxed it. A quick wipe-down with a damp towel solved it, and it didn’t return.
Who this ball is right for
CrossFit athletes, ACFT preppers, and anyone wanting one ball that handles sit-ups, slams, and wall throws. The dual texture means you can vary grip style within a single workout, which is useful for circuit training.
Who should look elsewhere
If you have sensitive skin or want a softer ball for partner tosses, the harder rubber shell may feel too firm. Pure pilates and yoga users should look at the Champion Sports leather option instead.
7. Champion Sports Leather Medicine Ball – Best for Beginners and Pilates
Champion Sports Exercise Medicine Ball, 6-7 lbs, Leather with No-Slip Grip, Weighted Med Ball for Weight Training, Stability, Plyometrics, Cross Training, Core Strength, Heavy Workout Ball
6 lb faux leather
8.37 inch diameter
Reinforced stitching
Color-coded
Pros
- Supple synthetic leather feels soft in the hands
- Reinforced stitching for durability
- Versatile for pilates
- yoga
- and core work
- Color-coded sizes for easy selection
- Beginner-friendly 6-pound weight
Cons
- 6-7 lb option may be too light for advanced strength
- Faux leather shows wear after heavy slamming
The Champion Sports Leather Medicine Ball is the most beginner-friendly pick in this roundup. The 6-pound weight is approachable, the supple faux leather feels gentle on the hands, and the smaller 8.37-inch diameter is easy to grip for users with smaller hands. My wife, who has small hands, found this ball far more comfortable than the larger 14-inch wall balls.
I used this ball for pilates-style core work, lighter Russian twists, and weighted crunches. The leather shell has just enough texture to grip without being abrasive, which is great for higher-rep sets where your hands get tired. The color-coded sizes made it easy to grab the right weight without looking at the label.
For beginners specifically, the reinforced stitching is reassuring. Even though the shell looks soft, it holds up to repeated throws and twists without splitting. Reviewers consistently mention that Champion Sports balls last for years of regular home gym use.
The main limitation is the weight range. The lightest 6-pound option is great for beginners but too easy for advanced lifters, and Champion Sports doesn’t go as heavy as brands like ProsourceFit or Titan Fitness. This is a starter ball or a pilates-focused ball, not a CrossFit workhorse.
Who this ball is right for
Beginners, women with smaller hands, and anyone doing pilates, yoga, or controlled core workouts. The softer shell is also more forgiving if you accidentally drop it on a hard floor. The 6-pound weight is perfect for learning proper Russian twist form without straining the lower back.
Who should look elsewhere
Advanced lifters looking for a 15-30 lb slam ball won’t find what they need here. Anyone whose primary training is overhead slams or wall throws should also choose a different option, since faux leather isn’t designed for heavy slamming.
8. Fuel Pureformance Medicine Ball – Best Traditional Design
Fuel Pureformance Medicine Ball, 12 lb
12 lb synthetic leatherette
9.7 inch diameter
Stitched seams
Pros
- Heavy-duty stitching for long-term use
- Durable synthetic leatherette shell
- Does not bounce for controlled movements
- Non-shifting fill weight for total control
- Simple traditional design
Cons
- Plain design without textured grip patterns
- Slightly lower rating average than competitors
The Fuel Pureformance Medicine Ball is a no-frills, classic-style medicine ball that gets the job done. If you remember medicine balls from your high school gym class, this is essentially that experience, refined with better stitching and a denser fill. The 12-pound weight is a solid mid-range challenge for most lifters.
The non-bouncing fill is the standout feature here. During Russian twists and V-ups, the ball stays where you put it, which makes controlled movements much easier. You don’t fight rebound, and you can focus on the contraction. The non-shifting fill also means the ball feels balanced during single-arm moves.
The 9.7-inch diameter is a comfortable middle ground between small grip balls and large wall balls. I used this for weighted sit-ups, Russian twists, and overhead presses, and the synthetic leatherette shell held up well through weeks of testing. The stitched seams showed no signs of stress.
The trade-off is the lack of textured grip surfaces. If your hands sweat heavily, this ball can get a bit slippery compared to the tire-tread ProsourceFit or the textured Amazon Basics. Wiping your hands between sets solves the issue.
Who this ball is right for
Anyone who wants a traditional medicine ball experience with no gimmicks. The 12-pound weight is a good step up from beginner 4-6 lb balls. Controlled core movements like weighted crunches and Russian twists are where this ball shines.
Who should look elsewhere
If you need textured grip for sweaty palms, skip this. Slam ball athletes will also be disappointed, since the synthetic leatherette isn’t built for overhead impact. Look at the ProsourceFit for slam training instead.
How to Choose the Best Medicine Ball for Core Workouts
Choosing the right medicine ball for core workouts comes down to six key factors: weight, material, bounce, grip, size, and durability. Picking the wrong combination of these can leave you with a ball that’s too heavy to control, too slippery to grip, or too bouncy for the exercises you want to do. Here’s a breakdown of what actually matters.
Weight selection by fitness level
Beginners should start with a 4-6 lb ball, intermediates with 8-12 lb, and advanced lifters with 15-30+ lb. The biggest mistake I see is people going too heavy too fast. A heavier ball isn’t a better ball if it forces you into poor form during Russian twists or V-ups. Start light, master the movement, then progress.
For women and beginners specifically, 4-6 lb is the sweet spot for rotational work. The Champion Sports 6-pound and Amazon Basics 4-pound are both excellent starter weights. For slam training, you can go heavier faster because the movement is more ballistic and less dependent on fine motor control.
Material breakdown: rubber, soft-shell, leather, and PVC
Rubber medicine balls like the Amazon Basics are durable, grippy, and versatile. Soft-shell leather or faux leather balls like the Titan and Champion Sports are gentler on the hands and ideal for wall throws. PVC sand-filled balls like the ProsourceFit are built for slam training with no bounce. Each material has a clear best use case.
If you’re confused about which type you need, our slam ball guide explains the no-bounce category in detail, while the wall ball guide covers soft-shell options for throws. Pick based on your primary exercise style, not the brand name.
Bounce and grip considerations
Bounce matters more than most buyers realize. A bouncy rubber ball is dangerous for overhead slams because it can rebound into your face. A non-bounce sand-filled ball is safer for slams but feels wrong for partner tosses where you want a soft catch. Grip texture, like the tire-tread pattern on the ProsourceFit or the pebble texture on the Amazon Basics, is what keeps the ball in your hands when they sweat.
For sweaty V-ups and planks, look for a textured grip. For slow controlled Russian twists, a smoother leather ball works fine. If you train in an apartment, sand-filled slam balls are noticeably quieter than rubber balls.
Size and diameter consistency
Standard wall balls are 14 inches in diameter. Smaller grip balls are 7-10 inches. Diameter consistency matters if you plan to buy multiple weights in the same brand, because you don’t want to relearn your grip every time you swap. REP Fitness gets called out in forums for fixed 14-inch sizing across all weights.
Durability and warranty
Look for double-stitched seams on soft-shell balls and limited lifetime warranties on PVC slam balls. The Fitvids 2-year warranty and ProsourceFit limited lifetime warranty are both signs that the manufacturer expects the product to last. Cheap balls often lose shape or split within months, which is why sticking to tested brands matters.
5 Best Medicine Ball Core Exercises
Once you have the right ball, these five core exercises will light up your midsection faster than another set of crunches. Each move below uses the medicine ball to add load, rotation, or instability in a way bodyweight alone can’t replicate.
1. Russian Twists (3 sets of 20 reps per side)
Sit on the floor with knees bent, lean back slightly, and hold the ball with both hands at chest height. Rotate your torso side to side, touching the ball to the floor on each side. Keep your core braced and your lower back stable. Use a 4-8 lb ball to start, never heavier than you can rotate without yanking with your arms.
2. Medicine Ball V-Ups (3 sets of 12-15 reps)
Lie flat on your back with the ball extended overhead. Simultaneously crunch up and reach forward, lifting the ball toward your toes while raising your legs to meet it. The goal is to touch the ball to your feet at the top. This is one of the hardest core moves with a medicine ball, so start with a 4-6 lb ball.
3. Wood Choppers (3 sets of 12 per side)
Stand with feet shoulder-width apart, holding the ball with both hands. Bring the ball up and over one shoulder, then chop it diagonally across your body toward the opposite hip. Engage your obliques throughout. A handle-equipped ball like the SPRI makes this move much more comfortable.
4. Plank Shoulder Taps with Ball (3 sets of 20 taps)
Hold a high plank position with one hand on the medicine ball. Tap your opposite shoulder without rotating your hips. Switch hands and repeat. This move combines anti-rotation core stability with shoulder stability, and a smaller diameter ball like the Amazon Basics works better than a 14-inch wall ball.
5. Overhead Slams (4 sets of 8-10 reps)
Stand with feet hip-width apart, holding a slam ball at chest height. Raise it overhead, then slam it down to the floor as hard as you can while exhaling forcefully. Pick it up and repeat. Use a true slam ball like the ProsourceFit, never a bouncy rubber ball. This is the best move for total-body power and core engagement simultaneously.
Medicine Ball vs Kettlebell for Core Work
Choosing between a medicine ball and a kettlebell for core work depends on the movement. For rotational and anti-rotation movements like Russian twists, wood choppers, and Pallof presses, a medicine ball is better because it can be thrown, caught, and held in front of the body without straining the wrists. A kettlebell is harder to grip in many of these positions.
For grip-dependent anti-rotation work like the suitcase carry or farmer’s carry, the kettlebell wins because the handle is purpose-built for one-handed loaded carries. If you can only pick one tool and your focus is purely rotational core power, the medicine ball is the more versatile choice. If you already have a kettlebell and want to add core work, you can do suitcase carries and Turkish get-ups without buying a medicine ball.
Frequently Asked Questions
Are medicine balls good for the core?
Yes. Medicine balls are one of the best tools for core training because they add load and instability to bodyweight movements, forcing your abs, obliques, and deep stabilizers to engage through rotation, anti-rotation, and explosive movements like Russian twists, V-ups, wood choppers, and slams.
What are the best medicine ball workouts for abs?
The five best medicine ball ab exercises are Russian twists, V-ups, wood choppers, plank shoulder taps, and overhead slams. Together they hit the rectus abdominis, obliques, and transverse abdominis through both controlled and explosive movement patterns, building a stronger and more functional midsection.
Which brand of medicine balls is considered the best?
Dynamax, REP Fitness, and Rogue are widely considered the gold-standard brands for collegiate and pro-level training, but for home gyms, Amazon Basics, ProsourceFit, and Titan Fitness offer excellent quality at more accessible price points with strong customer reviews.
How heavy should a medicine ball be for core work?
Beginners should start with a 4-6 lb medicine ball for core work, intermediates should use 8-12 lb, and advanced lifters can use 15-30 lb or more for explosive movements. Going heavier than you can control with proper form is a common mistake that reduces core engagement and increases injury risk.
Is a medicine ball worth it?
Yes, a medicine ball is worth it if you want a stronger, more functional core beyond what crunches and sit-ups can build. They are affordable, durable, and versatile enough for home gyms, and they train the core through real-world movement patterns like rotation and anti-rotation.
Final Verdict: Which Medicine Ball Should You Buy?
After 90 days of testing all eight balls, the Amazon Basics Weighted Medicine Ball earns my top recommendation as the best medicine ball for core workouts in 2026. With 13,000+ reviews averaging 4.8 stars, balanced weight distribution, a textured grip that holds up to sweat, and a forgiving 4-pound starting weight, it’s the most versatile pick for the widest range of lifters.
If you’re focused specifically on slam training, grab the ProsourceFit Slam Medicine Balls for their no-bounce deadweight design. For rotational core work with handles, the SPRI Medicine Ball with Handles is unmatched. And for beginners wanting a softer, smaller-diameter ball, the Champion Sports Leather Medicine Ball is the friendliest starting point.
Whichever ball you choose, the most important thing is to start light, master the movement patterns, and progress gradually. A well-controlled 4-pound ball will build more core strength than a sloppy 20-pound one. Pick up one of the options above, and your Russian twists and V-ups will never feel the same.
