Leather Gym Bag

This is not to support the back, because that would be a weight lifting belt.
I speak during the day when they are away from the gym. I noticed that Hulk Hogan is still one of his clothes every day. What's inside the leather bag? All lifters are not diabetic, they are.

Maybe the pills Digitalis when they have heart palpitations all the efforts and lifting? Or one of these additional "thongy-things" they wear.

because they can

Probably because they are always wearing sweat pants without pockets.

So you have something you can put your car keys in the gym while your in shorts spandex.
