hybridAF: Hybrid Training

Lift heavy. Run fast. hybridAF turns both halves of your training into one number. The Hybrid Score combines your strength and your cardio engine using a harmonic mean, each side graded against published population standards. Being good at half of it does not move the number, and the number falls when you stop training. Built for hybrid athletes: people who lift and run and refuse to pick one, including anyone training for HYROX or a race while holding onto their strength. WHAT YOU GET One score you cannot fake by being good at half of it Strength and engine are graded separately on the same ladder, then combined so a weak side pulls the total down. Six qualities sit behind it: upper strength, lower strength, VO2, speed, stamina and grind. Recovery that changes the plan Connect Apple Health and hybridAF reads your HRV, resting heart rate, sleep and strain, then tells you when to push and when to hold back. A week that fits your actual life The planner puts sessions in the real gaps in your calendar, shaped by your goal and pulled back when your recovery is low, then writes them into Google Calendar. Reschedule by chat. Every session, mapped Splits, heart rate zones, power curves, estimated 1RM and PRs, from your own data. Import your lifting history from Strong or Hevy, and your runs and rides from Strava. A coach that knows your numbers Atlas reads your training, recovery and plan, then answers in plain language: what to do today, why your score moved, what to fix next. See where you stand Optional leaderboards rank you against other hybrid athletes on the metrics that matter. SHOW YOUR WORK Every metric is documented at hybridaf.app/science, with the research behind it and a plain statement of which parts are our own design choices rather than published science. hybridAF runs on the web and on your phone.
