1.Development of graduated strength: Switch from assisted pullups to unassisted pullups through adjustable resistance levels ranging from 75 to 225 lb. The bands adapt to your growing strength and allow gradual adjustments in the challenge for continuous muscle building during bodyweight training 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 musculature: 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 ensure lasting elasticity for constant resistance, while skinfriendly surfaces prevent irritation. The heavyduty Dring enhances stability during training and provides , tearresistant performance for pull training across fitness levels
