P90X

I have ordered these workout videos called the P90X and I am excited to start using them. My boyfriend and his son got me introduced to them. They have been using them for four weeks now and I have noticed changes in there bodies. As I get older my body seems to be getting soft and I do not like that at all. I definately am in need of a change. I truly believe if I can stick to this I will be on an upward climb out of the softness. I can only hope.
