You can do P90X Pull-ups!

"The Women's Health Big Book of Exercises" taught me a cool trick for doing assisted pull-ups! I cannot do even one pull-up on my own, but author Adam Campbell suggests using superbands for assistance.
I've never really been good at using a chair to assist with pull-ups during my P90X workouts. I always end up using my legs to push me up instead of pulling up with my arms. If your like me, you probably don't want to invest in a big, bulky pull-up machine so superbands are the way to go. Superbandsare flat resistance bands that are looped and basically look like giant rubber bands.
Steps for doing assisted pull-ups:
1. Loop the end of your band around you P90X pull-up bar and through the other end of the band securing close to the bar.
2. Place your hands in position for the type of pull-up you'll be doing and then place your knees (or feet of you have a long band)in the bottom of the superband.
3. Proceed with pull-up exercise.

Now your doing pull-ups! And eventually, with some practice, you'll be doing them on your own!
