Which Medicine Ball Weight Should You Buy? A Simple Guide
Most people buy a medicine ball that is too heavy. For core and rotation work, control matters far more than weight – a ball you can move cleanly for 10 reps beats one that turns every rep into a lower-back exercise.

- Your lower back rounds or you hold your breath? Too heavy.
- 10 goblet squats feel easy after the second set? You can go heavier for leg work later.
Medicine ball or slam ball?
A classic medicine ball (faux leather, stable filling) is made for holding, rotating, squatting and passing to a partner. A slam ball has a thick rubber shell and is built to be thrown hard onto the floor. If you train in a flat with neighbours below, a medicine ball is the better choice anyway.
What to look for
- grippy surface – smooth balls slip with sweaty hands
- weight printed on the ball
- shape-stable filling that does not shift
