Review: Great belt for the price - Sizing seems weird .. according to the chart I wear a xl … it feels very secure and supportive without digging in to my torso and thats even with it pulled tight . The quality feels top notch compared to my harbinger belt I have had for years . So far very happy with this belt . Great price and provides core support when lifting heavy . Just in case you want to know this is not to support your lower back but to stabilize it in heavy lifts . Still use proper form .
Review: Great support for heavy lifting - This lifting belt feels very strong and supportive during workouts. It gives great lower back support when lifting heavy weights and feels secure without being uncomfortable. The quality is really good, easy to adjust, and perfect for squats, deadlifts, and other heavy lifts. Definitely a great gym purchase!
