Bodyblade Exerciser is unique, unlike any other piece of exercise equipment on the market today. Bodyblade is a reactive, oscillating device that utilizes inertia to generate up to 270 muscle contractions per minute. Most other systems work on the principle of the user attempting to lift a weighted item or stretch an elastic band. This fitness equipment however, works on the opposite premise: Once the ends begin to move, inertia wants to keep them in motion and it’s up to you to resist. Thus, the risk of injury through overexertion is greatly reduced. In addition, Bodyblade Exerciser will directly impact whatever sport you play by specifically targeting those muscle groups used in a particular sport. Many of the exercises you perform with this fitness accessory mimic the same movements athletes use in competition, allowing you to train your body to execute moves faster and with more force. With Bodyblade there are no weights or elastic bands that can break. You control the intensity and acceleration of the movement, which makes it safer and more effective than other equipment. Bodyblade is technically known as a dynamic reactive instrument, which means that it matches the force you put into the blade and nothing more. As it moves back and forth four and half times per second, it uses the principles of inertia to stimulate the muscles and make them stronger. The better conditioned the user, the more enhanced the workout will be. Yet since the user controls the movement, you can never injure yourself with Body blade. All of this is possible due to the patented technology and the inertial exercise principles built into every Body blade.
