VO2 Max Training vs The Magic Apps Interval Timer

PEAKVO2 is a VO2 max training app built around the interval protocols that actually move the needle: Norwegian 4x4, Tabata, HIIT 30/30, and more. Pick a workout, press start, and the app guides you through every phase: warm-up, work intervals, recovery, and cooldown. Why VO2 max? VO2 max is the single best predictor of cardiovascular fitness and long-term health. Improving it doesn't require guesswork, it requires the right intervals, done consistently. PEAKVO2 gives you both. What's included: 24 science-backed interval protocols, including the Norwegian 4x4, Tabata, and HIIT 30/30 Build your own custom interval workouts Color-coded workout timer with automatic phase transitions Activity tracking with streak, year in review, and training minutes Works with running, cycling, rowing, and indoor cardio Free to start. 4 workouts are yours forever — no strings attached.
