Arm strength Bar, Chest Expander Adjustable Power Twister Bar, 2 Way Arm Pull Bar Arm Muscle Exerciser with 4 Springs Strength Trainer, Portable Spring Resistance Exercise Gym, 30-80 kg

Built with 4 pair 8 pieces super-tough, steel springs. These high grade springs can withstand even the most intense workout sessions. Four groups of double-layer springs are freely combined, with one inner spring and one outer spring in each group. The resistance of the inner spring is 8 kg/ root and the resistance of the outer spring is 12 kg/ root. The resistance bar is detachable through the knob at the top. You can freely disassemble the number of springs to combine different resistances, and you can freely carry out full-body training from 30 kg-80 kg.

Two-way training mode, you can change the combination direction of spring and handle, one is from outside to inside and the other is from inside to outside. Different training modes aim at training different muscle groups. The springs are compressed, which is different from the power twister that required users to twist the springs. Our improved design provides a better longitudinal operation range of motion, and eliminates any risk of rebound and breakage. 4 pair 8 pieces springs work together to make the resistance output more uniform, and therefore stimulate muscles more efficiently.

Sculpt and engage all muscle groups in the body with this multi-functional, portable workout equipment – all-in-one, at home back workout, shoulder workout, bicep workout, ab trainer, arm & chest workout equipment for men & women.

Is compact and easy to transport, making fitness accessible to everyone, regardless of space, time or budget constraints!
