Powering
Performance.
FXV reads your body every morning — sleep, HRV, resting heart rate — and writes the day's session to match. Strength & aerobic, GPS run tracking, live heart-rate zones, cycle-aware. Twelve weeks. No guesswork.
Twelve weeks of progressive overload — squat, deadlift, press, pull. Loads scale to your 1RM, reps to your RIR, sessions to your readiness.
PM sessions slot at least 6 hours after morning lifts. Zone 2 base builds across the block — intervals added when the phase calls for them. Concurrent training rules baked in, not bolted on.
HRV, sleep stages, resting heart rate — pulled from Apple Health overnight. Score under 40? The app drops volume. Over 80? It pushes intensity.
Miss a session, feel wrecked, smash a PR — tell the coach. It rewrites the rest of the week to match what your body actually did, not what the spreadsheet said it would. Every change shows its reasoning.
Polar H10, Apple Watch, Garmin, Wahoo — pair in seconds and FXV uses them all. Apple Health pulls overnight sleep, HRV and resting HR automatically. Live HR streams to the session screen during workouts.
Three 4-week mesocycles — accumulate, intensify, deload. Periodisation baked in.
RPE-anchored, science-backed. Strength and aerobic blocks built to match your goals and modality.
HRV, sleep stages and resting HR scored every morning. Today's session bends to it.

Most training apps ignore the menstrual cycle. FXV reads where you are in yours and shapes the day's session — heavy when your body's primed, lighter when it isn't, restorative when it should be. Optional. Private. Always under your control.
