Yesterday I saw some old man walking around the gym in some semi-loose fitting tights with no shorts
Personally, I wouldn't wear tights without shorts at my gym, but I been wearing long tights
under my shorts since around 2009. They're mandatory for me on squat and dead-lift days.
The closest I came to it is when I wore a pair of my football pants to the gym if I couldn't find anything else, and even that was rare.
One of my boys tried rocking the T.O. to football practice...
Coach sent him back to the locker room so fast
