Flat Fist

What it does: focuses on the small muscles in the palm that bend the larger knuckles and straighten the small joints. These muscles help you to get a firmer grasp around a handle for increased stability, and are used for fine motor manipulation of the fingers.

Recommended for: golf, tennis, baseball mitt grasp, fishing, marksmanship.

How to execute: place the center of the ergonomic bar on the thumb tip and line up a button to the base of each finger. Keep small finger joints straight while bending only the larger knuckles to press buttons.


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.
