  1. All you guys hating on this technology are missing the point. If you are an athlete that trains explosive movement, this seems like an excellent tool. Its not for regular people just looking to be fit and healthy.

  2. Speed is not the key to bodybuilding because you’r actually relying on your momentum rather than your own muscle strength.

    There are only 3 factors that will help you to build muscle:
    1. Dynamic contraction of muscles
    2. Metabolic stress
    3. Muscle Damage

    So, all you need to do is to increase your rep and do it SLOW to put more stress on your muscle.
