Check price on AmazonSelecting the right medicine ball for CrossFit is crucial because the demands of wall balls, slams, and overhead throws require a ball that can withstand repeated abuse while providing a comfortable, secure grip.

How to choose
- Weight Selection. Choose a medicine ball weight that matches your strength level and the intended exercise. For CrossFit wall balls, women typically use 14 lbs and men 20 lbs, but beginners should consider lighter options to achieve proper depth and form.
- Material and Durability. Rubber shells are the most durable for slams and outdoor use, while vinyl or fluid-filled balls offer a softer feel. Look for thick, seamless construction to prevent cracking from repeated drops on concrete.
- Bounce Characteristics. Wall balls require a consistent, predictable bounce for rebounding. A moderate bounce is ideal, while dead bounce balls are better for slam drills to prevent wild rolls and maintain safety.
- Grip and Texture. A tacky or textured surface helps maintain control when hands are sweaty. Smooth balls can become slippery during high-rep sets, so prioritize models with a sticky or rubberized grip for CrossFit.
- Size and Fit. Medicine balls come in various diameters, which can affect your mechanics on wall balls. Ensure the ball fits comfortably between your hands and against your chest for proper clean and throw motions.
Frequently asked questions
What weight medicine ball should I use for CrossFit wall balls?
Standard weights are 14 lbs for women and 20 lbs for men in most CrossFit workouts, but beginners may start with 10 lbs to focus on form. Choose a weight that allows you to hit the target consistently while maintaining a full squat depth.
Can I use a medicine ball for slams in CrossFit?
Yes, but you need a ball designed for slams, such as a dead bounce medicine ball. Standard balls with high bounce can rebound unpredictably and cause injury. Look for thick rubber or sand-filled options that absorb impact and remain still on the ground.
How do I clean and maintain a medicine ball?
Wipe down the ball with a mild soap and water solution after each use to remove sweat and dirt. Avoid abrasive cleaners that can damage the surface. Store the ball in a climate-controlled area to prevent rubber from drying out or cracking.
What is the difference between a medicine ball and a slam ball?
Medicine balls have a consistent bounce and are meant for throwing, catching, and rebounding drills. Slam balls are designed to have minimal bounce, absorbing impact and staying put, making them safer for overhead slams and ground strikes.
Are heavier medicine balls larger in diameter?
Generally, heavier medicine balls have larger diameters, but some brands offer multiple weights in the same size for consistency. Check the specifications before buying, especially if you need a specific diameter for wall ball target practice.
Which brand is most durable for CrossFit medicine balls?
Rogue Fitness and Dynamax are widely considered the most durable for CrossFit. Rogue's Sunny Health & Fitness 20 lb Slam Medicine Ball has a tough rubber shell, while Dynamax's fluid-filled bags last long with proper care. Again Faster and Rep Fitness also offer very durable options at lower prices.

The Rogue Sunny Health & Fitness 20 lb Slam Medicine Ball is our top pick for CrossFit because it combines excellent grip, consistent bounce, and rugged durability that holds up to daily high-intensity use.
