We've all seen "that guy" or "that girl" at the local gym. It's that guy, the A.C. Slater look-a-like, who sports the spaghetti-strap tank top to show off those huge biceps. And it's the girl who wears the one-piece leotard underneath the 10-year-old tie-dye shirt.

Even though you shouldn't worry too much about your looks while you're at the gym, at least be respectable!

Here's a few tips to get you on your way:

Guys, wear a fairly new and clean t-shirt. Trash those shirts with the yellow pit-stains -- it isn't exactly going to attract that cute girl on the treadmill beside you.

Girls, instead of distracting "that guy" with your good looks and low-cut tank top, try simply wearing something comfortable to exercise in -- a fitted t-shirt and yoga pants.

Guys, make sure to only wear tennis shoes to the gym (and clean ones, at that!). It's not symbolic of your manhood to wear cowboy boots or those muddy construction boots ... not to mention it's unsafe.

And girls, the black dress socks with the white tennis shoes will have every person snickering -- go with white or grey socks.
