I asked a question along these lines before and got a really great, thoughtful answer, but now I have another more specific question! Okay, my training schedule (given to me by my Team in Training coach) is a 6-day-a-week schedule--during the week I currently alternate 30 and 50 minute running sessions, with a long run on Saturday (currently 8 miles, this and the weekday sessions will build obviously). I take Sunday as my day off. When should I do my strength training? On my light running days or on my day off? Any suggestions about what I should do? I like Cathe tapes (obviously!) and I have CTX and Pure Strength on DVD and the new set pre-ordered. Should I go heavy or light? A full-body workout once a week, or parts on various days? I have to add (to further complicate matters!), the marathon training is really eating up my time and since I work full-time and have three young children, I need to find a quick routine. Basically, my goal now is just to keep my muscles, joints, and ligaments healthy and supported while I do my marathon training.
