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.

Bi-Stretch™ vs. Ordinary Foot Rollers

Improvement Validated by Science

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.

Iliopsoas Stretch

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

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.

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.
