One Leg Oblique Abdominal Crunch with Balance Ball

Video Transcript

" Hi! This is Manny Castro, Exercise Physiologist. Another variation of the crunch with the ball under the legs and also stimulates the balance is to raise the leg off the ball and that will also force you to use different muscles and I will explain. Use the same position as we use previously in the previous exercise and we raise one leg off. Right when you lift this leg off the ball, you are already feeling a little more pressure on this side. What that does is that engages the obliques also. So anyway, in keeping consistent with the form you need to use for your crunches, what you would do is cross your hands over and notice that in all these exercises I am not putting my hands behind my neck or my head. The reason for that is, once you do this you tend to pull up on your head, which all it does is just stimulate cheating. What I’ll do is put my arms across my arms forward. Also, if you want to use on all of these exercises for crunches, if you want to use another variation you can put your arms back and it puts more resistance also on the abdominals. So any ay, to keep it simple, what we’ll do is we’ll cross arms over, keep your leg up and we are going to focus on one spot on the roof and bring your chin up towards that spot. If you want to put more variation into this, you can also do an oblique exercise where you are going opposite shoulder to opposite knee, in other words. You stimulate the obliques."
