Damn computer addiction
But... just got a Weider 9400 full gym system for $400, and will get a few odds & ends to suppliment what that can't do. It's been too long since I've worked out, and I've become weak & have a nice "computer desk gut" - similar to beer belly, but due to differing circumstances, lol.
I'm pretty strong over all, but being 6'6", I just don't show it as easily as the shorter guys.
