Tidal Qi
Read full descriptionHide full description
Every champion performance begins with breath. Tidal Qi is the precision breathing companion built for athletes who know that how you breathe is as important as how you train. Designed with ice skaters in mind — where breath control shapes artistic expression, sustains endurance through demanding programs, and steadies nerves before the moment that counts — Tidal Qi is equally at home with runners, cyclists, swimmers, gymnasts, and any athlete for whom rhythm and breath are inseparable. What Tidal Qi does: Track your breathing rate, depth, and rhythm in real time during training and performance Visualise your breathing patterns across a session to identify where breath control breaks down under exertion Set personal breathing targets tied to specific phases of a routine or race Review session history to spot trends and measure progress over time Guided breathing exercises to build capacity, calm pre-competition nerves, and accelerate recovery between efforts Built for the ice. Ready for everywhere. Whether you're landing a triple axel, holding a layback spin, or pushing through the final lap, Tidal Qi gives you the awareness to stay composed, stay powerful, and stay in control. Your breath is your foundation. Train it like everything else. The name — "Tidal" from tidal volume, the breath that sustains you; "Qi" from the life force that flows through it. Together, the rhythm that drives performance.
