One of my favorite lifts is weighted pull ups. That being said, I have a question about technique. When i was in high school working with a body builder on strength training for wrestling I made incredible gains. The exercises that i did where squats, pull ups, dead lifts, and power cleans. The guy I worked with said that when doing weighted pull ups, it is more beneficial to only go down to 45 degrees then back up. He said that 90 percent of the lats are worked in that range, and the extra reps you can pump out are more beneficial then going down till your arms are straight. I have been getting a lot of flack from people then, and now about not going the whole way down. I usually just let it go, but i would like to know your opinions on this. Should I stick with what I'm doing, or go down till my arms are nearly straight?
