Thumb Pinch

What it does: provides isolated strength to the thumb and the side of the index finger for a strong lateral hold. Strengthens thumb and index finger for greater stability and coordination. Particularly great for bass players, drummers, marching band musicians or anyone needing a firm, controlled grip on their instrument.

How to execute: place the palm bar on the inside of the bent index finger. With the tip of the thumb slightly bent, flex the thumb on the first button. Note: for increased resistance, flex the thumb tip on the first two buttons at the same time.


If you experience pain or fatigue – stop immediately. As with any exercise, excessive or incorrect use can lead to pain or injury. Therefore progress slowly and increase reps and resistance very cautiously.
