Side Static Hold Abs

In this exercise all you have to do is to stay static. It may seem easy but it's not as easy as you think, and the fact that you have to stay static it's the hardest part of it. First you have to put one of your hands closed and the elbow of the same arm on the floor parallel to your body and then, with your body sideways and completely straight, put your feet also sideways one the floor (one over the other one), and with your other hand in your waist you'll have to stay static in that position as much time as you can. Then you'll have to do the exactly same thing but turned to the other side.

Details: Try to find something fluffy to put under your elbow.
