Great form on the OHP. I like how you shove your head forward as the bar goes over your head. You're supposed to do that. Good job.

As for delt raises, I mention in a completely different thread (unless it's this one, lol) that I don't like rear delt flys/raises like that because I have a hard time hitting my rear delts with them. So on my part, if you can really feel it in your rear delts (it's a small muscle, so believe me any stimulus there is going to be very recognizable) then you're probably doing it right.
