Exercise ball combination crunch/pushup
by Jim Wordsworth
(Syndney, Australia)
Using the exercise ball I like to combine the two exercises - the prone knees to chest crunch and the pushups on the ball:
1. Lie forward onto the exercise ball and walk yourself forward so that your exercise ball is under your feet. This is the starting position.
2. Tighten your abdomninal muscles and pull your knees to your chest
3. Hold this for a second
4. Extend your legs again so that they are straight
4. Lower your chest to the floor and push back up.
5. Repeat 1 to 4.
You may want to start with 3 sets of 5 until you build up your strength and work your way up to 3 sets of 12. I would also advise that anyone trying this be able to do the knees to the chest crunches and the pushups separately before they combine the two exercise ball exercises.
I like to teach this to my more advanced clients at the gym where I work as a personal trainer.
