Two-layer waist protection system provides firm trunk support, reducing pressure on the waist and spine and delivering robust lumbar protection during lifts. Increases lifting efficiency: helps you lift heavier and perform more reps, overcome plateaus, and boost overall training volume while ensuring muscles are trained effectively. Efficient power transfer: applies pressure to the waist and abdomen to stabilize the core, enabling steadier force application, improved movement efficiency, and better posture. A stable core helps prevent injuries and enhances gym performance. Comfort and protection: Double-Fit design lets you adjust the fit for a personalized feel. The waistband is made of EVA and contours to your waist curve to provide protection, comfort, and durable performance. Durability and comfort: good rebound and softness ensure a comfortable, long-lasting lift experience. Use scenarios: - For squats and deadlifts to stabilize the trunk during maximal or near-maximal lifts. - During strength blocks to push max weight, more reps, and higher training volume. - In long training days or competitions to maintain core stability and proper posture.
