What makes the RX5 a "double belt" design and why does it matter?

The RX5 features dual nylon straps that create a double-layered closure system, providing greater stability and resistance to belt shift during maximal lifts compared to single-strap designs. This is particularly beneficial for heavy squats and deadlifts where maintaining consistent belt position throughout the lift is critical for both performance and safety.

What is the difference between the RX4 and RX5?

The RX4 uses polyester mesh with a single nylon strap closure — well suited for general gym training and moderate lifting. The RX5 uses premium polyester with dual nylon straps and a heavier-duty iron buckle — designed for powerlifting-style maximal compound lifts. If you regularly train squats and deadlifts at 90%+ of your 1RM, the RX5 is the better choice.

How do I choose the right size?

Measure your waist at navel height. S fits waists up to 30 inches, M fits 30–34 inches, L fits 34–38 inches, XL fits 38+ inches. The iron buckle and hook-and-loop closure allow adjustment within each size, so fit one size if you are between two.

Should I wear the belt above or below my belly button?

Position the belt so its centre sits at or just below your navel, covering the lower lumbar and upper hip area. This placement maximises intra-abdominal pressure support for deadlifts and squats. Some lifters adjust slightly higher for overhead press. Experiment with position during warm-up sets to find what feels most secure when bracing at maximal effort.
