This simple workout is based on a classic scissors move, but is modified here to extend the exercise’s benefits to upper-body elements of the arms, abs, and obliques.

1. Lie on your left side with legs stacked and left elbow down.
2. Use your left hand to support your head. Position your right palm flat on the floor at chest level.

   

3. Push off the floor with your right hand to lift your upper body while simultaneously raising your right leg as high as possible.

   

   

4. Return to your original position and do a total of 12 reps.
5. Reverse position to lie on your right side and repeat with the same 12 reps.
6. Cycle through three sets of this fat-burning workout.
