I am currently trying to get fit. With 2 kids at home this has not been easy. So I decided to try the 30 day shred. I can say I do feel fitter but I am only on level 1. Have watched level 2 I already feel pain without doing it. I am still waiting for this extra energy people talk about but it has not come. This could be to bad sleep. But there has been another side effect I did not see. That is my son increasing his imaginary play. He now stops watching his movie to go and play with his Legos. My boy would watch stuff on Netflix forever if he got his way and after I have had no sleep he gets more than I would like. So him choosing to do something else while I work out is an add motivational bonus.
