Jim, it looks like you're using a thumbless grip (left hand) on that barbell bench press. I know that it feels good, but I hope you're being VERY careful with that lift, especially when training by yourself (which I assume is virtually all of the time). Needless to say, if the bar slips out of your hands, you could be toast. YouTube is loaded with clips of just that happening to all kinds of trainees, and when it happens, it happens frighteningly FAST. Be careful, my friend!
When I bench heavier I'll use my thumb, but for light sets like this I don't.
