I'd probably have to stop at 2 since I can't lift heavy objects like I used to. When I was a techie, I'd haul 90 lb monitors around no problem. Now I have trouble moving my tv set a short distance. As for the 280 - there would be no way I'd be able to budge that, considering that it's well over my body weight...although I'd be able to push myself away from the weights. LOL!
I've got about 200 lbs more to go before I'm back to where I was on my bench. I may be too old now to do so. I guess we'll find out. I'd always wanted to break 500 on a flat bench. Gotta have realistic goals after all... ;-)
