Hi! I appreciate the two-week free trial to Total Access to look around the site. However, as I'm more of a DVD exerciser, I have the lower body (Ultimate Leg etc) and ab/core videos, and ordered the flexibility, upper body, and toned body videos. In regards to the lower body, do I complete all the exercises in a session? DVD 1 is separated into chapters and I don't understand how that relates to Level 1 Part A or Level 1 Part B that I've seen mentioned in your workout schedules. The abs workout video doesn't have the chapter breaks so I assume an exercise session would include all of it? Not having the other 3 videos yet I don't know if I'll have similar questions regarding their formats. My other question is: how long does exercising only one body area per week (as in the 5-day schedule) get those muscle groups toned? I'm not a "beast mode" exerciser but am more familiar with working body parts on a split schedule (I'm figuring to exercise M-F generally). I'm 64, walk about 10 miles per week but want to build strength and tone muscles, as wow, whatever muscle tone I coasted on before menopause definitely left afterwards, lol. Thanks!
