Here
we work the oblique and intercostals. Side leg raises work the entire side
of the torso
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.
