Infinity Circadian 4D DualFlex
Circadian 4D DualFlex combines dual massage mechanisms with a flexible track and extensive arm, calf and foot work. Infinity’s AI description starts with a thumb scan of wellness indicators, then recommends a program; the manual also describes intensity and technique adjustment. Saved routines and voice commands add convenience, while the underlying AI and fatigue-score validation remain undisclosed.
