Stretching exercises with Range3D

Range3D operates on the principle of static stretching. The exercises start from a comfortable neutral position and the user can progress up to the normal range of motion and beyond if necessary. A ratchet mechanism holds the leg support in the stretching position, so no effort is required by the user. The leg can be either moved further into the stretch or returned to neutral by releasing the ratchet. No adjustments are needed between the exercises.
