Fitness apparatus e.g. arm press for e.g. building musculoskeletal system of human being, generates mechanical tension in elastic elements in response to user force and has elastic element that produces counter-force to user force
The fitness apparatus (1) has elastic element (2) and force application areas (10,14), to which a user applies a force for training purposes on the fitness apparatus. The apparatus is formed so that the mechanical tension in the elastic elements is generated in response to user force and the elastic element produces a counter-force to user force. The elastic element comprises polyurethane elastomer based diisocyanate, polyurethane elastomer based naphthylene , polyurethane elastomer based 1,5-naphthalene diisocyanate, and polyurethane elastomer based polyester polyols.
