AGS: Two Core Functions to Alleviate Shoulder Fatigue 🩸 Restoring Blood Circulation: The repetitive rebound mechanism creates dynamic decompression intervals, preventing the compression of muscles and blood vessels to maintain optimal blood flow. 🦴 Reducing Intervertebral Disc Pressure: Through periodic decompression, it allows the intervertebral discs to expand, continuously pumping in hydration and essential nutrients to maintain structural integrity. Four Core Benefits ⏱️ Delaying Fatigue: Facilitates the efficient removal of metabolic waste, thereby sustaining muscle strength. ⚡ Mitigating Soreness: Prevents the accumulation of metabolites, extending comfortable load-bearing time by 50%. 🛡️ Preventing Chronic Strain: Preserves muscular and spinal strength, enhancing the body's resilience against impact forces. 🏃♂️ Conserving Energy: Minimizes muscular compensation, significantly reducing overall energy expenditure. 🔬 Scientifically proven to reduce pressure by 30%.
