Don't rely on your pants size: S (fits waist 70-80 cm), M (fits waist 80-90 cm), L (fits waist 90-100 cm), XL (fits waist 100-110 cm). Make sure you measure your size using the size chart and measuring instructions in the size chart. Measuring based on your pants size can result in the wrong belt size. If your waist measurement is between two sizes, choose the larger size for an optimal fit. Durability and flexibility: genuine cowhide leather is used in these 7 mm thick weightlifting belts for men and women to maximize pressure absorption and control. By helping users harness their inner strength, these belts are useful in various fitness and training programs, including deadlifts, squats, Olympic lifts, and cross-training. Optimized lumbar support: We offer belts in 10 cm and 15 cm, both with a wider back support for superior lumbar support and to help you strengthen yourself for lifts. This unisex weightlifting belt is perfect for intense training with various exercise machines. We offer different colors and sizes so you can choose the belt that best suits your style and preferences. Enhanced reliability: The adjustable roller buckle is made of high-quality industrial steel and features a double-pin design to prevent the belt from slipping. Reinforced rivets work together with the roller buckle for maximum support. Improved adjustability: The double-pin buckle can be adjusted using 10 precision-drilled holes for a perfect fit in your training belt, while an attached leather flap prevents direct contact between the buckle and your body, minimizing discomfort.
