This premium freestanding punching bag is built for high-intensity home training, featuring a cutting-edge 4-spring shock absorption system that delivers 15-45degree(s) fast rebound and 360degree(s) shock/noise reduction. The dual absorber design significantly dampens impact force, reducing joint strain and floor vibration, making it ideal for heavy kicks and punches. It stands at 70'' tall, suitable for users from teens to adults (47-73'' tall), supporting full-body kickboxing, strength training, and stress relief. The 5mm thick Abs base with 12 strong suction cups provides rock-solid stability when filled with sand (up to 205lbs), preventing movement even during aggressive training. Constructed with multi-layer materials-including 2mm premium Pu leather, high-density Epe foam, and a stainless steel tube-it withstands years of repeated use. The kit includes a pair of 12oz boxing gloves with 7mm thick foam and pre-curved design for optimal protection.
