I think htese are probably all good videos but I'm wondering if there is anyone out there who has completed STS, CLX, and P90X. Are all three worth while? What would you say the biggest differences are between them? I've done P90X and am wondering where to go from here. STS is so tempting but I'm just curious how it compares to all the others. Again I know they are all good but am really looking to see if anyone can give me some good comaprisons between them. Thanks so much!!
