XM Fitness Pro Power Grips

Have been using the ball regularly for over 2 months and works great

XM makes very sturdy solid sound products. I have the 50lb slam ball. Love the tyre tread vs the no tread. Hurts a bit on skin but better than the ball slipping. Perfect. So far its been durable and feels durable.

Smaller slam balls eg 10 or. 15 lbs. ]can be used for traditional med. Ball exercises in addition to a slam ball. The size and holdable surface allow this.
