Dumbbell Squat + Push Press + Row

This combination is called a complex, but its actually quite simple. You’ll complete a set (10 reps) of one exercise, then move to the next exercise in the complex. Since each exercise begins in a similar position—standing with dumbbells, for instance—you don’t waste time setting up between exercises. The result: You accomplish more work in a shorter time, so your heart rate stays elevated, and you burn a lot of calories.

Stand holding dumbbells at your sides,

1. Lower your body until your thighs are parallel to the floor.
2. Then push back up and repeat 10 times. Without pausing, bring the dumbbells to your shoulders and hold them with your palms forward, dip down at the knees.
3. Then straighten your legs and thrust the weights overhead.
4. Do 10 repetition. Next, bend forward at the waist until your back is almost parallel to the floor.
5. Pull the weights up to your rib cage.
6. Lower them, and repeat for 10 repetitions.
