About Isohold

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! You'll know the round is completed when the phone buzzes and vibrates in your hand. The app then will show your time.
