## Description

Strength + aerobic in one programme. AI coach that reads your HRV, sleep, and load — and adjusts tomorrow's session before you wake up.

FXV is an AI-coached training app for athletes who want to know why their programme says what it says. No black-box scoring. Every
  number ships with its formula.

  THE PROGRAMME
  A 12-week macrocycle, three 4-week mesos, written from your training history, equipment, and benchmarks. Strength + aerobic concurrent.
  PM sessions slot at least six hours after morning lifts so you don't blunt your own adaptation.

  The plan adapts every morning. HRV down 18%? The engine drops the lifting volume before you wake up. Sleep under 6 hours? Z2 instead of
  intervals. Cycle phase? Each one shapes the week's load. You just open the app and train.

  THE LOAD MODEL
  Two channels — mechanical kilojoules from the bar (mass × ROM × reps × set × eccentric multiplier) and cardiac TRIMP from your real
  heart rate. Both are saved per session. Both have a budget. The drift between prescribed and actual feeds back into next block's
  prescription. Per Banister 1991 + Plagenhoef 1983 segmental masses for gymnastic movements (toes-to-bar, sit-ups, etc.) so accessory
  work isn't double-counted.

  THE COACH
  A real LLM coach with full programme + recovery context. Ask "why is my readiness 67?" and it cites the formula plugged in with your
  numbers. Ask "can I move tomorrow's run earlier?" and it actually adjusts the schedule. Six tool actions: cap RPE on a lift, shorten a
  session, swap an exercise, skip a session, set tempo, pair supersets.

  HEALTH TAB
  Six surfaces: Recovery (4-component readiness, RHR drift, HRV trend, sleep stages), Training Load (ACWR, polarization, strain budget),
  Sleep (4-axis score + 14-day debt), Body (weight, VO₂, body composition, wellness check-in), Tests (FTP, 5K, 2K row, Cooper benchmark
  protocols), Trends (longitudinal VO₂ + strength PRs).

  IN-SESSION
  Strength: full lifts list, current set highlighted, tap-and-log, slide-up rest timer with RPE prompt. Aerobic: pace hero with
  green-when-on-target, live zone bar, screen-on outdoor mode for sunlight running.

  DEVICES
  Apple Health for HRV / RHR / sleep / VO₂. Direct Bluetooth pairing for Polar / Garmin / Wahoo HR straps in-session. GPS run tracking
  with background updates.

  NOT MAGIC
  Every formula is from peer-reviewed research, citations published at fxvperformance.com/methodology. Confidence flags surface where you
  have less than 14 days of data — Coach refers to them when prescribing.

  Free during beta. Bring your bar, your strap, and twelve weeks of intent.
