The Slimmer in 7 Days Workout

How It Works

Need to get fit fast? We asked top instructors from 24 Hour Fitness club's sweatastic 24 S.E.T. class to give us their favorite toners for this one-week, whip-you-into-wow plan. "The results you get from the combination of strength and endurance training [S.E.T.] that's built into these total-body moves are far superior to anything else I've seen," says veteran instructor Jill Aucoin in Arvada, Colorado. No wonder: You'll burn 300 calories per 35-minute session -- as much as by jogging -- and firm every inch of flab.

Perform this circuit twice -- start over after completing the first round -- in the order shown, alternating the faster-paced cardio endurance bursts called Movers (using 2- to 5-pound weights) with the sculpting strength exercises called Shapers (using heavier 6- to 10-pound weights). Keep your rhythm as snappy as you can for the Movers while maintaining good form; take it slow for the Shapers and try not to pause between exercises. Beginners can use one set of the lighter (2- to 5-pound) dumbbells throughout or perform the Movers without weights. Do three Mover-Shaper workouts during the week on nonconsecutive days. On days in between, pick one of our Faster Calorie Blaster sessions or do 30 minutes of your favorite cardio.

What You'll Need: Two sets of 2- to 10-pound dumbbells.
