Don’t wear anything heavy because that can limit your movements or hide mistakes in your posture.
Clothes that reveal
If you're working out a specific part of your body, it's worth it to wear something tight that will let you visibly see the muscles working out.
Sports shoes
When purchasing walking or running shoes, make sure they bend at the ball. If it bends at mid-foot you won’t get much support.

Protect your hands
Wearing gloves will give you a better grip by preventing your hands from sliding off barbells, dumbbells or handles. It will also prevent your hands from getting blisters and calluses that can occur when lifting heavy weights.
Heavy weights
To lessen the moisture on your hands and enhance your grip, try rubbing chalk in between the palms of your hands. This works particularly well when you’re lifting heavy weights.
