"The more muscles you work, the more calories you burn," says B.J. Gaddour, C.S.C.S., owner of StreamFIT.com. Instead of splitting up your workouts by individual body parts -- like legs or chest -- train your entire body at once. Done at a high-speed, these three total-body exercises from Gaddour will blast more calories per minute than a typical weight-training exercise or cardio drill. Swap them into your current routine for bigger strength gains and a smaller waistline in less time.

And if you want more fat-loss moves like these, enroll in The Ultimate Boot Camp Workout. Designed by Gaddour, the routine contains a series of 10 intense exercises that will help you torch belly fat, pack on muscle, and sweat your way to a six-pack.

DIRECTIONS
Starting with the dumbbell hot potato squat, do as many reps as you can in 50 seconds. Then rest for 10 seconds as you transition to the next exercise. After you’ve done all three moves, rest for 1 minute and repeat the moves one more time.

Dumbbell Hot Potato Squat
The hot potato squat may sound like a kid's recess activity, but don't be fooled -- it’s also a cutting-edge fat-loss exercise that will get your heart pumping and your muscles burning in almost no time, says Gaddour. It starts with one of the most effective exercises invented: The squat. When done correctly, a squat trains a lot of muscles, particularly big ones like your quadriceps, hamstrings and glutes. In fact, it burns more calories per rep than almost any other exercise.
