Can you ask your friend to spot you when you are lifting those db's. When they get to be that heavy it is nice to have a buddy back there. Give the camera to a bystander.
PH, when I get spotted I feel as if I was cheating. I knew I could handle the dumbells, if anything I would simply drop them.
Louden, yes lockouts are very good. I had two people come up to me and ask me why I was "cheating". I wonder peoples reaction if I were to do floor presses.`
