IronMind Twist Yo' Wrist
IronMind says its Twist Yo' Wrist will help you treat yo'self with "a new spin on lower arm training." Regular sessions with the fitness companion should build strength, endurance, and muscle mass simultaneously in your grip, wrists, and forearms with a design that focuses on a thumbs- and pinkies-up position. This radial / ulnar deviation is the opposite of traditional wrist curl exercises and wrist roller equipment.
Twist Yo' Wrist is recommended for climbers, arm wrestlers, martial artists, and hand gun shooters who want to see gains from their elbows to their fingertips. Equipment includes a 4" diameter polymer roller, 4' climbing-grade cord, and carabiner clip to attach the Twist Yo' Wrist to a weight plate.
