 Has anyone tried the p90x exercise program?
jakecarpenter: Does anyone know of an open-source alternative? I don't mean "lift up heavy shit until you get tired, don't eat bad food" either, I mean a tested, regimented, and focused system?I participated in the 911 Fitness Challenge http://www.911fitness.com/ a few years ago and it was particularly helpful to have everything spelled out for you, but it was expensive to implement, given the gym membership and dietary requirements.
