I have tested out my mastery for WP/PE1 and WP/PE2 without a problem. Today I have been trying out WP/PE3 without success. Every time I transition from knuckle to wrist my arm wants to bend at the elbow. So basically I cannot put my wrist flat down on the ground while keeping my arm straight. Should I just work on it until I can do it with straight arms?
I just took a quick look at WP/PE4 and it seems that the athlete does not lay his wristr comletely flat on the ground.
