What You Need: One or two sets of dumbbells (3 to 8 pounds), yoga mat, and supportive sneakers.
Warm-Up: For circuit workouts, march in place, do arm circles and half squats, and twist and bend your torso, all without weights, for 2 minutes. For your favorite cardio workout, begin at an easy intensity and build up to a moderate or vigorous level over 2 to 3 minutes. A warm-up is already built into the yoga routine. (Search: Best warm-up routines)
Cool-Down: Finish circuit and favorite cardio workouts by stretching the muscles you just worked for 2 minutes. A cool-down is already part of the yoga routine.
Days: 1, 2, 3, and 5; Do Circuit moves and Power Drill sequence 6 times. After each Power Drill, rest 20 seconds (easy march or side-to-side steps) before repeating.
The Expert: Certified personal trainer and yoga instructor Chris Freytag designed this workout based on her DVD 10 Pound Slimdown ($18; exercisetv.tv/slimdown).
