I started P90X the day after my 40th birthday - March 15th- at the time I played hockey once a week and tried to get to the gym 2-3 days. I was 192 lbs on a 5'-9" frame. After my first 90 days I was 172lbs - shredded with a bonified 6 pack. This program is awesome. Since then I have done P90X+ and now on insanity. I am going back to P90X program next week as I found it was the best of all programs.
I highly recommend it to anyone as there is minimal equipment needed. As they say Decide, Commit, Succeed.
OK off my soap box for the morning. Have a great day!
