How to use
Hold one trainer in the hand so the fingers rest on the top and the thumb on the opposing side, then squeeze until the handles come together and slowly release. Perform sets of controlled repetitions with each hand, adjusting the number of repetitions and rest intervals according to training goals or rehabilitation protocols. Use both units alternately or simultaneously to maintain muscular balance. For rehabilitation, follow a physiotherapist's guidance on repetitions and progression.
Usage recommendations
Start sessions with a warm-up of the wrist and fingers, use controlled movements to avoid sudden strain, and increase repetition volume gradually. If pain or unusual discomfort occurs, reduce intensity and consult a healthcare professional. Clean surfaces with a damp cloth and store the trainers in a dry place to preserve condition.
