Wear sleeveless shirts
Yell with every rep
Imaginary lat syndrome
Taking pics of yourself
Walking around with a gallon of water
Wearing sun glasses
My thoughts:
Better than wearing a sleeveless shirt, wear no shirt at all.

Rather than yelling with every rep, folks should sing Hallelujah! with each successful rep.

If you really want to show off your lats, hold your arms over your head while spinning around every so often so folks get the full impact from all sides.

I prefer to ask others to take my picture or better yet a video....especially when I am shirtless, holding my arms over my head and singing Hallelujah.

Forget the jug of water and either walk around with a gallon of Vodka martinis and a pocket full of green olives or skip to the drinking fountain between each and every set, leaving your sweaty towel on the equipment to save your place until you get back.

I've found wearing either swimming goggles or the kind you wear when you tan is better than wearing sunglasses. Sometimes wearing a monocle is more appropriate.

If you must wear street clothes, wear them in the Sauna.

Most of all, don't go to the gym to lift and get fit, go to have fun while chatting it up with everyone you can.....especially when you are naked in the locker room. Folks really love that.

I'm being serious....really.
