If I was going to bench press twice my bodyweight, I should have done it a long time ago. At 68 years, this isn't likely to happen any time soon. My excuse, besides being old is that my arms are 36" long (sleeve length). This is a heck of a long ways to push up that weight when you are only 5'11" tall. I see guys at the gym lifting amazing amounts of weight in the bench press all the time. Invariably, they are stubby little fellows with short arms.
I gave up trying to be the strong man at the gym a long time ago. I am consistent, I don't take 500 trips to the drinking fountain, I don't chew the fat with my friends for 20 minutes between sets. I come to the gym to workout. That's what I do, get in and get it done....boom!
