I have heard great things about your videos and have been looking at the different videos on your website to purchase. My question is probably a simple one . . . is it really necessary to work a different body part each day? I have used the "Firm" workout videos in the past two months that combine both aerobics and total body weight training in the same workout and I'm wondering if I should not have been doing those every day either (especially considering I haven't seen hardly any results with them . . . which is why I'm here!!) Basically, is it more effective to do separate strength training and cardio workouts on opposite days as opposed to doing the videotapes that combine them in the same workout? Considering I only have about an hour each morning to work out, I don't think I could do BOTH in the same morning after looking at your tapes, unless I'm missing something? How often would you suggest weight training as opposed to cardio for a "beginner" and could you suggest your favorite "beginner" tapes?
