Close the Gap Straps™

Isometronic training for grippers inspired by John Brookfield's "strap holds" is a way to focus on finishing off a tough gripper. Hang some weight from the strap, clamp down on the handles, and squeeze extra hard or the strap will slip out--and get stronger.

Pair of straps: one at 1/8" (3 mm) thick and one at 9/16" (14 mm) thick. (Plate and gripper not included.)
