I just want to put this out there I'm a scientific evidence based Strength & Conditioning Coach based in Jackson WY. I work with some of the best endurance/ultra-endurance athletes in the world, mountain guides and former Olympians. If any of the fraternity here has fitness questions they would like answered from a sports science perspective I will gladly answer them. FWIW - Stuff like Crossfit, P90x or any "general program" with a name, isn't science based. I'm not interested "well it works for me" debates and they're purely a waste of my time.
