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.

8 Professional Stretching Programs

8 scientifically designed stretching programs tailored to different muscle groups and activity scenarios, delivering a comprehensive and effective recovery solution.

Cycling Stretch

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

Iliopsoas Stretch

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

PNF Stretch

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

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.

Recovery Stretch

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

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.

Lower Body Stretch

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