About VO2 Max Trainer: Fitness Age
Your VO2 max is a number. VO2 Max Trainer turns it into a training plan. Start from your current level, choose a goal, and see a realistic path forward.

START WITH YOUR NUMBER - Import Cardio Fitness readings from Apple Health. - Enter a result from a lab, watch, wearable, or previous test. - Get a starting estimate from your age, profile, and activity history. - Run a guided Cooper 12-minute, 1.5-mile, or Rockport 1-mile field test. FOLLOW A PROGRESSIVE PLAN - Choose from beginner, intermediate, and advanced programs lasting 8 to 12 weeks. - Set a VO2 max goal and see an estimated time to reach it based on your current level and weekly training dose. - Follow the next scheduled session or choose any workout when your week changes. TRAIN WITH 38 PROTOCOLS - Norwegian 4x4, 5 x 3, 8 x 2, Seiler 4 x 8, Billat 30/30, Ronnestad 30/15, Tabata, and more. - Dedicated packs for VO2 max intervals, short intervals, threshold, Zone 2, sprints, beginners, and field tests. - Switch sessions between running, walking, cycling, rowing, SkiErg, stairs, swimming, elliptical, Air Bike, or bodyweight. - Build a quick session or create and save your own interval workout.
