2. DONKEY KICKS

Start with your knees and hands on the floor. Make sure that your back is straight and you look right in front of you. Personal trainers point out that if your back bends in any way, it may lead to serious backaches. Now, take a breath and straighten one leg back. Hold it in the upper position for five seconds and then put it into the starting position while breathing out. Repeat for both legs.
