Things You'll Need:
- an exercise ball
-
Step 1
Start by positioning yourself correctly on the exercise ball. You want the ball to rest right on your lower back, not touching your behind (puts stress on your back), but also not up near your shoulder blades (makes crunches too easy). Plant your feet about shoulder length apart with both feet completely touching the floor. Place your hands onto your opposite shoulder, creating a criss-cross pattern. Never do crunches with your hands behind your head, as this will put stress on your neck and shoulders
-
Step 2
Begin the crunch by slowly lowering yourself down. The slower you move, the more of a workout your abs will get. Make sure you are completely in control and take a quick hesitation before coming back up again.
-
Step 3
Make sure you are contracting your abs as you begin to move back up. Think only about contracting your abs and trying to crack an invisible located in between your abs. Move slowly upwards until you get to the top of your motion and then begin to move slowly back down again.
-
Step 4
Do a set of 15-20 controlled crunches and then take a break. If you feel your abs beginning to exhaust themselves and feel new pressure on your back, stop and consider it the end of your set. Do two to three sets throughout the day and your abs should be looking great in no time
