VO2 Max Trainer vs Zenith

Boost your VO2 max, one of the strongest predictors of endurance performance and of how long and how well you live. Measure your true VO2 max in 15 minutes or less, raise it with Zone 2 and HIIT workouts, and beat the rest of the world on a verified global leaderboard. iPhone and Apple Watch. NEW: GHOST RACE Race a ghost during your Cooper test, Balke test or 1.5 mile (2.4 km) run. Pick your best run, your 12-week goal, the athlete 10 places above you on the leaderboard, the #1 of your age group, an Olympic record, or any VO2 max you choose. The gap shows live in meters or yards, green when you lead and orange when you chase, with voice cues when you pass or get passed. Follow the race on the Lock Screen, in the Dynamic Island and on your Apple Watch, even without your iPhone. The result saves as a normal test, and you can share a "Me vs ghost" card. MEASURE YOUR VO2 MAX - Beep test 20 m and 15 m (bleep test, PACER test, multistage fitness test, Leger shuttle run) - Yo-Yo Intermittent Recovery test, levels 1 and 2 (YYIR1, YYIR2) - Cooper test (12-minute run) - Balke test (15-minute run) - 1.5 mile / 2.4 km run test Results are compared with age and sex norms. FIND YOUR TRUE MAX HEART RATE AND LACTATE THRESHOLD The 220 minus age formula can be off by 10 to 20 beats per minute. Run a beep test with a heart rate monitor and the app records your real maximum heart rate and estimates your lactate threshold from how your heart rate responds as the pace rises, with no lab and no blood test. Your Zone 2 and HIIT zones are then built from your own threshold. TRAIN TO IMPROVE IT - Zone 2 training with personal heart rate limits and Apple Watch haptics when you drift out of zone - HIIT and interval workouts: Norwegian 4x4, Tabata, Gibala, 30/30, EMOM, Myoreps - Free mode to log any session - Custom workout builder: work, rest, repeat blocks, warm-up and cool-down - A 12-week training plan built from your current fitness level - An AI coach on the Plan tab that tells you what to do today and why GLOBAL LEADERBOARD WITH VERIFIED RESULTS Compare your VO2 max with athletes worldwide by age, sex, country and job. A score only reaches the leaderboard after anti-cheat checks: GPS, heart rate (Apple Watch or a chest strap), cadence and vehicle detection. Verification badges show how each result was checked. O2 POINTS AND RANKS VO2 max moves slowly, so O2 Points show the work you put in every day. Every minute with heart rate earns points, harder zones earn more, and 80/20 training, following your plan and retesting give boosts. Climb 7 ranks, from Reserve Duty to Norwegian Cyborg.
