swiss ball intermediate exercise

In every gym I've been to, a swiss ball is always presence. Of course u could do more than just sitting down on it. While performing any exercise on a swiss ball, its best to keep your mid section tight therefore you do not feel any pressure on your lower back. 
This two exercise is a little tough but challenging nonetheless, try it at the end of your workout, 3 sets of 10 slow and controlled repetition.bam
