ABSTRACT:
A device for counteracting knee joint pressure in quadriceps training including a rotatable resistance arm having a foot attachment device connected to the resistance arm where the foot attachment device includes an elastic member and the axis of rotation of the person's knee and of the resistance arm are displaced from one another in such a way that the leg of the user during the stretching out movement is subjected to a tractional force from the elastic member due to the fact that the point of attachment of the attachment device on the foot travels along one arc during the rotational movement that is different from the point of attachment of the attachment device on the resistance arm.
