The TherapyTrainer HandCycle is the perfect upper-body trainer. The bike offers smooth adjustable magnetic resistance in both the forward and reverse direction. The TherapyTrainer has more than twice the resistance range of other portable upper body trainers on the market. The TherapyTrainer is quiet, durable and will give you a complete upper body workout. The Multi-Grip Ergo Handles provide users with the ability to target multiple upper body muscles groups during workouts, simply by changing the position of their hands on the handles. The Multi-Grip Ergo Handles also provide the user with a more comfortable grip. The handles fit the natural arches of the hand for a more natural grasp pattern. The San Francisco 49ers use the TherapyTrainer HandCycle to provide their quarterbacks with a more comprehensive pre-game warm-up. Their Sports Trainers use the TherapyTrainer in their training room for strengthening and rehabilitation of shoulders and rotator cuffs. We tested the Multi-Grip Ergo Handles with Physical and Occupational Therapists. Here are just a couple comments we"ve received from them. "I feel that the baseball grips have allowed me to be more creative with treatment options using gentle resistance with patients recovering from shoulder surgeries." "Placing the hands of patients who are survivors of spinal cord injuries in ergonomically correct positions around the ball grips has enhanced their neurological recovery and improved self esteem in those without grasp patterns."
