Isometric, static muscle strength is foundational in many precision sports.

Isohold uses motion detection to help you train your arms' isometric hold. Used with or without wrist weights, it allows a target shooter to improve stability of their hold after a lift or transition.

An excellent companion to your routine practice! Use Isohold anywhere you have your phone with. Just a few minutes per day to make a difference. The difficulty level can be adjusted separately for shake and twist of your grip.

Adjust the difficulty, hit the button, and do your best holding the device after 3 second countdown! The app will show your time once you've finished.
