Created by Physical Therapist Bruce Hymanson, Bodyblade pioneered vibration and inertia training in 1991. With its patented design, Bodyblade uses vibration and inertia to produce rapid muscle contractions up to 270 times per minute that will transform your body. No other training device or machine can offer the same quality core stability exercises, shoulder and pelvic stabilization, and overall vibration training benefits. As a unique reactive training tool, Bodyblade was created to strengthen, tone, and transform the shape of your body and the deep dynamic stabilizers of the spine and core. Bodyblade exercises can be used during rehabilitation to regain joint stability and core strength or incorporated into sports performance training, personal training, and fitness routines. There is nothing to put together, simply open the box and you are ready for a complete body workout in minutes.
