Sometimes it may be tempting to just head over to the gym in whatever you're wearing, but don't make that mistake. This is especially important when it comes to footwear, because shoes that do not properly cushion your feet could lead to serious damage when running, jumping, or kicking. Don't wear earrings or other jewelry, as they could get caught in the equipment and cause a very painful situation.

Also, don't wear anything that is too tight, as you want proper circulation throughout your body while exercising.
