1. Decompression Waist Belt: Improper posture and overstretching can slowly cause lower back problems. Stretching for 2-3 minutes a day can help improve back pain, relieve nerve pain, and increase flexibility. 2. Multi-posture stretching: no longer suffering from handstands. Lifting or dangling your legs stops the decompression because your core muscles tighten. Lowering the feet allows the body to relax and increases the stretch in the back. 3. Underarm Pad Design: When stretched, the downward pull can cause underarm pain. The underarm pads are designed to reduce some friction to relieve underarm discomfort and improve comfort. 4. If you do not feel improvement after one treatment, do not panic. Just give your body more time to adapt. Experiment a lot to find a stretch that works for your body. 5. Material: nylon + diving material 6. Only the straps are included in the package, you need to prepare the pull-up bar by yourself.
