2011 Double-T Sports Transformation Challenge!

[angelajones]

To Double-T:

Enos Jones was a contest winner in the Double-T contest last year in Nov. 2010. It has almost been a year and the $450 check + supplements have never been mailed. Muscle Chick and others haven't received their prizes either. Despite promises, your company hasn't sent anything to us. I would like to be told the truth for once. When can Enos and others expect our prize money?

Muscular endurance is very important for people playing sports and who have to sustain an activity for long periods of time. Muscular endurance is determined by how well your slow twitch muscle fibers are developed. In case your wondering what slow twitch muscle fibers are, I will explain. There are generally two types of muscle fibers in your body, slow twitch and fast twitch. Slow twitch muscle fibers cannot exert as much force as fast twitch, but can sustain an effort over a much greater period of time. Fast twitch muscle fibers can exert a great amount of force but for a very limited amount of time. Therefore, slow twitch equals endurance, while fast twitch equals strength.
