How to use the D-ball

Slam and throw as much as you want – even on hard and rough surfaces. The best part? You can train wherever you like, even if that’s outdoors on rugged terrain.

Unlike a sand-filled slam ball, the D-ball is specially designed to help you sustain repetitive drills and movements with some limited rebound. It’s often compared to a sand-filled ball that completely dies or a soft shell medicine ball that has too much of a bounce.

Similar to the Dynamax Medicine Ball, the 14” design keeps the shoulders in a neutral position, making it safer and easier to throw and catch.

With weights ranging from 10-150lbs, you can get the athletic training your body needs to level-up your strength and power. Heavier weights are also available upon request.

"Dynamax is the only way to go"

Dynamax is the only way to go, I have gone with cheaper ones before trying to save money and the material is not even close… most are too slick for gripping.

    How is the slam ball different from your medicine ball?
    The D-ball can be slammed and thrown against rough surfaces. That’s because it’s built with a tougher outer shell and core structure.
    How heavy should my slam ball be?
    You should be able to feel some resistance in your movements, but your range of motion shouldn’t be too restricted. If performing slams, you’ll need to be able to lift the ball above your head. If you’re just starting out, a lighter weight of 10-20lbs is recommended. A lighter weight can also help you move faster and improve accuracy with new movements. Heavier weights are effective for building strength.
    Are slam balls durable?
    The Dynamax medicine ball is built to be highly durable and withstand the toughest of workouts, even on rough terrain. Made with a robust core structure that won’t shift and a strong PVC outer shell, you can be confident that your slam ball is built with explosive and high intensity training in mind.
