It supports a wide range of sports, including the big three (squats, deadlifts, bench press), powerlifting, bodybuilding, physique, and CrossFit. Compared to conventional gym belts and power belts, the stability and support for the lower back are significantly improved. This belt is ideal for trainees from beginners to advanced users who "want to handle heavy weights safely." [Revolutionary 4-Stage Fine-Adjustment Lever Action System] This innovative lever-action system achieves precise "4-stage fine-adjustment function," which was impossible with conventional pin-type belts and buckle-type training belts. Until now, lever-action belts could only be adjusted in one stage, and many users were dissatisfied with the fit. ALLOUT's new lever-action training belt allows for "4-stage fine adjustments." It achieves the optimal fit for the sport and exercise, such as tightening it firmly to fix the lower back during squats and loosening it slightly to secure the range of motion during deadlifts. Furthermore, it can be tightened and released with a single touch, eliminating the hassle of searching for hole positions like with conventional pin-type belts, making it easy to use even for beginners. It is widely used as a squat belt, deadlift belt, power belt, and gym waist belt. [High-Durability Lever & Double Stitching | Tough Design That Doesn't Break Easily] High-durability specifications for peace of mind even with daily hard use at the gym.

Furthermore, reinforcement with double stitching makes it less likely to fray even after long-term use, and the durability is significantly improved compared to conventional training belts. It boasts powerlifting-level strength and is a genuine specification recommended for those who feel uneasy about their lower back.
