PrimeBuild™ 5-in-1 Grip Strength Kit – Hand & Forearm Trainer

Stronger hands, heavier lifts. Five tools, one kit.

The PrimeBuild™ 5-in-1 Grip Strength Kit puts a complete hand and forearm session in one box: an adjustable gripper that dials from 11 to 132 lbs with a built-in counter, plus a finger stretcher, a grip ring and a stress ball. It is made for adults whose grip gives out before their back does on deadlifts, rows, pull-ups and heavy carries.

Use it at home between sets, at the desk during a call, or keep it in the gym bag for a warm-up before you reach for the bar.
