Leg Aside Abs

To do Leg Aside Abs all you have to do is to put into the Static Hold Abs position (put your elbows and your hands closed on the floor parallel to your body in order to sustain it, then, put just the tips of your feet on the floor with your body completely straight and your arms doing a 90º angle). Once you're in the Static Hold Abs position raise one of your legs, put it aside and thrust it forward as much as you can, and then, do it with both legs alternately as much times as you can.

A good variation of this exercise is the Leg Aside Push-ups.
