Here is a trainer designed for extension and flexion of the arms and legs in your body. The HCI Fitness eTrainer Passive Assist Motorized Trainer is designed for those of you who are bouncing back for severe injuries or dealing with mobility issues. The assisted exercise helps increase blood circulation and flow to your muscles.
The trainer is quiet and has two independent motors, allowing you to train upper and lower limbs simultaneously or separately. This piece of equipment is not right for everyone but could prove useful for rehab.
