Dip belts are a commonly used form of weight training. They are named for the dip exercise, one of the few and best known methods of adding resistance to it. It is also commonly used to add resistant to pull-ups and knee/leg raises in hanging from a pull-up bar. Unlike most weighted clothing, dip belts are not affixed to the body, but rather the weight suspends semi-secured to the usually leather belt, suspending from the back and generally kept up by resting on the gluteus.
