[quote=zk]Anybody tried or know much about p90x? I’ve always been skeptical about stuff like “muscle confusion.” It always seems like a gimmick to sell something. But a guy at work did it and he swears by it. He’s been running 30-40 miles a week for years (still does) and still, he says the p90x transformed him.[/quote]
Kind of opposite of the direction Walter is going. More of an aerobic type burn rather that getting strong.
