I know this question has been asked before, but I cant seem to find it. For those who are runners, how should I add sts as a total body workout for my cross training days? I will officially start my 1/2 marathon training, next week, for a marathon in Feb of 2011. I want to add sts as a total body work, working each body part twice a week. I know the program is designed to work each body part once a week, but I get the best results when I work each body part twice. Or should I even use the sts program and maybe use another series by cathe. I just love the results from the sts and dont want to give it up. Working each dvd, as it is designed, twice a week is overkill. Not to mention the time to complete the dvds in a single day...yikes! Any ideas or suggestions would be greatly appreciated, Thanks, V
