1.Controlled Resistance: Progress in unsupported pullups with adjustable resistance bands. The range 75225 lb supports the adjustment to the graduated force, helps users ly reduce support while improving back, arm and basic muscle strain 2.Safe resistance training: Minimize muscle tension with weight support technology, while the double foot pedal stabilizes posture. Reduces the risk of slipping and potential for injury and promotes confident pull progress through balanced force distribution 3.Activation of the whole body muscles: Designed to activate multiple muscle groups simultaneously, these resistance bands improve the effectiveness of training for accelerated muscle building 4. and skinfriendly support: Highdensity latex tubes provide lasting elasticity for constant resistance, while skinfriendly surfaces prevent irritation. The heavy Dring enhances stability during training
