Up until last week when I benched I went all the way down touched my chest and then went all the way to lockout. Then I was in the gym the other day and I got this guy to spot me on flat and he said that he only goes about 12-15 inches up. Not sure exactly about exact length. To just when the tri's start to take over. I did this and my chest was sore for four days after. I was watching the NFL combine the other day and saw some of them doing this also. Just curious if this was more of powerlifting or bodybuilding type of ROM.
