The specially designed hand trainer is used to develop and maintain the muscles of the fingers, hand, and forearm. The compression egg is utilized in many areas and applications. The main application of the hand trainer lies in therapeutic use. Whether at a physiotherapist or occupational therapist, in a therapy center, or simply training at home, the compression egg is your ideal partner for strengthening and toning your muscles. Training these muscles is particularly important as we activate them in our daily lives. Key muscles are engaged and utilized during everyday movements. In addition to the muscles of the hand and forearm, the fingers can also be trained individually or in combination with various exercises. The special egg-shaped design of the hand trainer was created according to specific guidelines. Previously, training was done with the classic round compression ball, but now a new anatomical shape has been developed. This shape now fits perfectly in the hand and provides a good grip. New training stimuli arise automatically through the different resistances. Therefore, you are constantly challenged and gradually increase your finger and hand strength while sustainably developing your muscles. Benefits: ergonomic shape, easy to clean, for strengthening hands and fingers.
