Side Leg Raises

What exercise does: These work the oblique and intercostals. Side leg raises work the entire side of the torso and truly help give your waist a narrow look from the front.

Implementation:
(A) Lie on your side, your lower leg should be bent under and for you Should use your elbow along with it to support yourself.
(B) Having the upper leg straight, lift it in a controlled manner as high as it will go, then bring it down again just short of making contact with the floor. Finish your reps with this leg, then turn onto your other side and complete the set with that leg. Try not to move your hips throughout this exercise.
