Some of the most common ones are powerlifting belts and bodybuilding/traditional belts.
Velcro belts can be easier to put on and remove than leather ones, and thicker belts can be more supportive of the spine.
BENEFITS OF BELT
A weightlifting belt has two main purposes. It reduces stress on the lower back while the person is lifting in an upright position, and it prevents back hyperextension during overhead lifts.
When Don't You Need a Weight Belt
Weightlifting belts are not necessary for other types of weight training exercises in which the spinal erectors do not work against heavy resistance.
How to Wear a Weight Belt
A belt must be worn tightly to maximize its usefulness.
– When performing maximal or submaximal lifts.
– While performing exercises which may cause the back to hyperextend.
