My two favorite DVDs:
• Hip Hop Abs: 3 workouts– Fat Burning Cardio, Ab Sculpt, Total Body Burn (instructor: )Shaun T
• SHAPE Long, Lean, and Strong (yoga with instructor Teri Hanson)
The first one is great because it uses dance moves, so it's fun to do, and you work up a good sweat. The second one is my favorite yoga video (I have 5-6) and I use this one almost exclusively. Teri's style is very fluid, she gives you good warm ups and cool downs, strengthens and stretches your body. My mom loves this workout, too, and my brother uses the Hip Hop Abs.
I got them both on Amazon.com for a really great price (got used copies).
God bless!
