Review on SPRI Chalk Block & Chalk Ball: Enhance Performance in Gymnastics, Rock Climbing, Bouldering, Rings, Weightlifting, Pool Billiards by Adam Abner

Bought this for my son who is a powerlifter. He uses wrist straps, which are very helpful, but his hands are often wet and blistered so gripping can be difficult (he works in the sun). The chalk helps keep his hands drier and improves grip. He feels more confident in his exercises because his arms aren't the strongest and he has the best support. It's small enough that he can get good coverage. At first he thought he needed loose chalk, but then decided this was better. Very happy with this item. I'm sure we will buy again if the need arises.
