I was attempting to perform some front-lever pullups the other day when I realized that I don't know what the proper form for the movement is. Specifically, I'm not sure how close the hands are supposed to get to the hips. I can get my hands to within 3-4 inches of my hips, but not quite to the point where they touch. Is this improper form? Should I do an easier exercise until I'm able to touch my hands to my hips on the FLPU? If not, how high up should I pull in order to do a 'correct' FLPU?
