I didn't think these guys really existed until Friday past.
There was on at my gym, about 5'9" or so, maybe 160 lbs. TapOut shorts, hoodie, hat... Took off hoodie to reveal, you guessed it, Tapout tank top.
And, I almost think he did it just so I could contribute to this thread, he was shadowboxing between sets of 45 lb. incline BD presses...
It was more sad than funny.
