I'm 5'8", 166 lbs today. 2 days ago I pressed 100 lbs, after I had been stuck at 95 lbs and resetting twice.
What helped me was getting some 1 lb ankle weights so that, after I reset back to 85 lbs, I could microload. Before my jumps were 5 lbs instead of 2 - 3 lbs.
My body goes a little forward at the top, too. I think it's supposed to at lockout.
I had the same problem with my presses, and I asked a general programming question in this thread in the Programming sub-forum:
Mixed novice / intermediate program?
Rob Is had very good advice for me in posts #3, especially #8, and see the last paragraph is #24.
