Medicine balls and slam balls can both add weighted, dynamic movements to your workouts, but they’re designed for different types of training. Medicine balls are a versatile option for throws, wall balls, rotational exercises, core work, and partner drills, making them a great addition for strength, conditioning, and athletic training.
Slam balls are specifically built to handle repeated high-impact slams into the ground. If your workouts include aggressive overhead slams and other movements where the ball repeatedly hits the floor with force, reach for a slam ball instead. If you want a weighted ball for wall throws, controlled exercises, and a wider variety of movements, a medicine ball is likely the better fit.
Choose the ball built for the work, then get moving.
