Open 11.6 Workout

This is the sixth workout of the 2011 Reebok CrossFit games open. It is a 7 minute AMRAP of two movements--a 100lb thruster and chest-to-bar pull ups.

The rep scheme is as follows:
3 thrusters
3 c2b pull ups
6 thrusters
6 c2b pull ups
9 thrusters
9 c2b pull ups
and so on and so on, as high as you can go within the allotted time.

I made it through 15 thrusters and 4 chest-to-bar pull ups before the seven minutes expired.
