Hybrid athletes lose strength to the wrong training mix. Koncur sequences your week around the concurrent-training literature — strength and endurance in the right order, with recovery you can actually see and a methodology you can actually read.
Concurrent science · Recovery-aware · Every formula cited
A 12-week macrocycle built from three 4-week blocks — Base, Build, Peak. Strength and endurance share the week without blunting each other: PM sessions slot at least six hours after morning lifts, the way the concurrent-training research says they should.
Two channels, both measured, both budgeted. Mechanical load in kilojoules from the bar; cardiac load as TRIMP from your real heart rate. The drift between what was prescribed and what you actually did feeds straight into next block's prescription.
A daily readiness score that decomposes into four parts you can read — Sleep, HRV, resting heart rate, and strain debt (acute : chronic load) — pulled continuously from Apple Health. Train hard when you're ready, deload before you break.
A real AI coach with your full programme and recovery in context. Ask why your readiness is what it is and it cites the formula with your numbers plugged in. Ask it to move tomorrow's run and it actually re-sequences the week — cap an RPE, shorten a session, swap a lift.
0.35·Sleep + 0.30·HRV + 0.20·RHR + 0.15·Strain → 67.
I've capped today's squats at RPE 7.
Koncur's load model, recovery scoring and programme logic are published openly, with a peer-reviewed citation behind every decision. If you want to know why your Tuesday session looks the way it does, the answer is on the page — not buried in a black box.

No. Your programme and load model are rule-based and published. The AI coach reads that logic and explains it — it cites the formula behind every number rather than inventing one.
No. Programmes adapt to what you have — barbell, dumbbells, bike, rower, run. Some tests go deeper with extra kit: the FTP test needs a power meter, for example.
Koncur reads HRV, resting heart rate, sleep stages, VO₂ max and workouts from Apple Health, and pairs directly with Bluetooth heart-rate straps in-session. Your data stays on your device and your account.
Four components: sleep (hours + deep/REM), overnight HRV, RHR drift from your 30-day baseline, and strain debt from acute:chronic load. The weighting is published — 0.35·Sleep + 0.30·HRV + 0.20·RHR + 0.15·Strain.
Koncur is the rebrand of FXV Performance. Your subscription carries over seamlessly through the rename — no action needed, no price change.
iOS first, because the recovery model leans on Apple Health. Android is on the roadmap once the methodology is fully proven on one platform.
