Some guys in my office started doing P-90X. They were talking about how excited they were to start getting back into shape. I went to check it out for myself and stumbled upon ATHLEAN-X. 90 days later my friends are in the same shape they were in when they first started P-90X. ATHLEAN-X has turned my body into a fat incinerating muscle building machine in about half the time. I look and feel better than I did 20 years ago.
