The QVC number for The Works Fitness DVD with 1,024 Cardio Workouts is F5068. I tried to access the number online, but it says you must call and talk to a customer service rep. Maybe they're out of stock and waitlisted. The instructor is Sharon Mann, a four-time Canadian Aerobic Champ according to the bio included with the DVD. Just tried the hi/lo and kickboxing yesterday and got a good workout. I felt like I wanted more than just the 2 aerobic segments, but it's easy to program in another workout and keep on going. I'm 51 with knee problems, but I'm also an advanced exerciser, and I worked up a sweat. The choreography isn't difficult, but it's great for a small space. The insert says there are Yoga/Pilates and Bodysculpting versions of The Works DVDs available, but I don't think they were available on QVC yet. Well worth the money.
