The 4 power strength coach is designed to train the muscular strength. The appearance surface is padded with a skid-proof rubber surface covered up with foam material.
The handles are situated in the recesses of the housing sides which are connected to feather/spring courses.
The respective traction power of the feather/spring courses is adjusted with the rotary switches on both sides, which are adjustable from 1 to 4 kg.
When releasing the grasps, they remain in the extended position in order to allow exercise changes.
After completing the training the locking switch is pushed aside, causing the handles to drive into the equipment again.
