The wrist is the part nobody trains. A spring frame that loads the wrist both ways, not just the squeeze.
What it is
A U-shaped frame on two steel springs. Your forearm goes through it, the padded arch rests against the arm and your hand holds the grip bar. Bending the wrist flexes the springs, so the load comes from the wrist angle rather than from a weight.
Spec
- Electroplated steel springs, foam-padded arch, grip bar
- Sliding collar adjusts the resistance
- About 10.4 × 5.5 in. (26.5 × 14 cm)
- Black, one size
- Works either hand
How it's used
- Forearm through the frame, pad on the arm, hand on the grip. Rest the arm on a bench or your thigh, palm down.
- Bend the wrist up against the spring. Slow down on the way back.
- Ten reps up, flip the hand over, ten reps down.
