This is the low-impact vibration trainer that provides the benefits of a 30-minute workout in just 10 minutes. Used by professional sports teams and medical rehabilitation and fitness centers, you simply perform a variety of exercises while standing or sitting on the broad 27" L x 23" W vibrating platform, or holding onto the vibrating handles. The trainer's vibration causes muscles to involuntarily contract 30 to 40 times per second, stimulating circulation, strengthening bones, stretching tendons and deep-lying pelvic muscles, resulting in faster recovery after workouts. Medical studies conducted over a 20-year period have shown that Whole Body Vibration causes less microtrauma to muscles than conventional weight training. The trainer's platform is made of durable fiber-reinforced plastic supported by a sturdy steel frame, enabling it to support up to 300 lbs. The platform oscillates at a frequency of 30-40Hz, has 30- and 60-second exercise intervals, and has two intensity levels. A remote control allows you to use any of the four exercise presets to focus on strength, stretching, massage, or relaxation. Plugs into AC. Silver. White glove delivery includes delivery into house and removal of packing materials. Please consult your physician before using this equipment. 59" H x 27" L x 35" W. (200 lbs.)
