How to use

Hold the hand grip with the palm around the handles and place your fingers on the upper handle. Set the desired resistance using the adjustment mechanism before starting the exercise. Squeeze the handles together in a controlled motion, then slowly release to the starting position. Perform sets of repetitions according to your training or rehabilitation plan, increasing resistance gradually as strength improves. For balanced development, perform exercises with both hands and combine gripping movements with finger-specific drills when required.

Usage recommendations

Begin training at the lower end of the resistance range and increase load in small increments to avoid overuse. Use the hand grip for short sessions several times a day during rehabilitation, and for longer, structured sets during strength training. If you experience pain beyond normal muscle fatigue, reduce resistance or stop and consult a healthcare professional.
