Talk about Bi-Stretch™

At the core of Bi-Stretch™ is the industry-first split calf intelligent control system. Like giving each leg its own “control center,” it analyzes differences with precision and delivers truly asymmetrical stretching. Powered by dual-core processors and ultra-fast algorithms, this intelligent network achieves a ±50 ms response time with trajectory-level accuracy of ±0.1° and ±1 mm—ensuring every stretch is precise, smooth, and efficient.

  • Split-Calf Independent Control

    Independent leg guidance supports precise, side-specific stretching to help address imbalances over time.

  • Dual-Core Motion Control

    Powerful processing enables ultra-fast response times of up to ±50 ms, keeping every stretch smooth, precise, and consistent.

  • Dual Signal Adaptive Sensing

    Continuously monitors position and tension, adjusting force and angle in real time to deliver a more personalized recovery experience.

  • Iliopsoas Stretch

    Targets hip tightness caused by prolonged sitting or core training, relieving lower-back pressure while improving posture and core stability.

  • Cycling Stretch

    Simulates cycling motions to dynamically extend the lower-body muscle chain, boosting leg circulation, reducing stiffness, and enhancing endurance.

  • PNF Stretch

    Uses professional “contract–relax” methods to improve muscle elasticity and flexibility by over 30%, while enhancing muscle control.

  • Recovery Stretch

    Gentle static stretching that helps the body shift into recovery mode, deeply relaxing muscles and easing post-workout soreness.

  • Full-Body Stretch

    Gently and smoothly stretches major muscle groups throughout the body, relieving tension in the shoulders, back, and legs while promoting deep relaxation.

  • Lower-Body Stretch

    Systematically targets muscles such as the quadriceps after high-intensity training to improve flexibility, accelerate recovery, and help prevent injury.

  • Piriformis Stretch

    Precisely releases the deep piriformis muscle to ease glute soreness and sciatic discomfort, increasing hip mobility.

  • Vitality Stretch

    Light, dynamic stretching to quickly activate the body, awaken muscles, boost blood flow, and increase neural readiness for exercise warm-up.
