Decent bench presses. You have a hell of an arch. It looks like your butt may be coming off the bench, but I cannot say for sure due to the lighting. Be more careful unracking the bar. Unrack with locked elbows and then pause briefly once the bar is in balance over the shoulder joint. Then, take a big breath in, hold it, and begin to move. Hold your breath for the duration of the lift. Right now you are breathing in on the way down and letting air out before your elbows are at full extension. Only breath at the top. Your grip is narrow, but if your shoulders are creaky, that may the width that works best for you.
