I feel my bench is very weak but I am unsure as to the reason why. In the last few weeks, my squat and my clean have gone up 5-10 pounds per week. My bench though is lucky to go up 5 pounds in a week or even two. My squat is between 280 and 300. My clean is 180 and my bench is only at 150. I weigh almost 170. I'm not sure if the problem is my form or if I just naturally suck at benching.
Is there a great bench press form video somewhere that I can look at? What other problems could there be?
Also, do you think I should be benching with my back mostly flat or with an arch?
