Not a template.
A real plan.
Tell exrsz your goal, deadline, level, schedule, equipment, and injuries. It generates a fully periodized program — proper phases, the right volume for your level, progressive overload, deloads where you need them, and a taper into your event. Then it keeps rewriting it as you train.
✓Runs, lifts, and hybrid in one coherent plan.
vsRunna is running. That's the whole menu.
✓Builds a real arc: base → build → peak → taper.
vsMost apps loop the same week or roll dice daily.
✓Adapts to your recovery and performance.
vsA static PDF reacts to nothing. Ever.
✓Knows lifting and running interfere — and spaces them.
vsTwo separate apps fighting over your legs.
✓Grounded in real coaching science (RPE, HR zones, volume landmarks).
vsA random workout spinner with a subscription.
It answers at 4am. Try it on day one.

Same science. Same plan. You just choose the bedside manner — from gentle to legally questionable.
Yes, you really can wake up to this every morning.

How it works
Three steps. No spreadsheets.
You've overcomplicated this for years. Here's the whole thing.
Tell us your goal
Goal, deadline, experience, days you can train, equipment, injuries. Takes about two minutes. Be honest. The plan is only as good as your answers.
Get your custom plan
Watch a real periodized program build itself — base, build, peak, taper. Volume and intensity for your level. Not someone else's.
Train. It adapts.
Log your work. exrsz reads your performance and recovery and rewrites next week accordingly. The plan keeps up with you. Novel concept.
Two minutes to set up. Then it does the thinking.
Everything in one app
One app. Fewer excuses.
Fourteen reasons your other six fitness apps can be deleted tonight. Plus one we haven't shipped yet.
AI program builder
Tell it your goal. Get a full, periodized, multi-week plan built from scratch. Not a template with your name pasted on top.
Adaptive plans
You were always going to miss a session. The plan reshuffles and moves on. Like an adult.
Readiness score
Pulls HRV, sleep, and resting HR from your watch into one number that tunes today's session. Train hard when you're ready. Not when a calendar says so.
Run AND lift, one plan
Stop running two apps with two plans that hate each other. exrsz spaces your hard legs day away from your hard run. On purpose.
Coach personality
Slide from Friendly to Ruthless. Want a hype man? Done. Want to be verbally destroyed at 6am? Tick the waiver.
Adaptive + readiness
Your plan changes
when you do.
exrsz pulls HRV, sleep, and resting heart rate from your watch into one daily readiness score, then tunes today's session to match. Slept four hours and your HRV tanked? It backs you off — so you don't turn a hard week into an injury and six weeks off.
Train hard when you're ready. Back off when you're not. Progress faster. Break less. Wild idea, we know.

Train with everyone.
Accountability works because letting people watch you quit is embarrassing. Feed, leaderboards, streaks. Use them shamelessly.

FAQ
The questions you were
already typing.
Still stuck? Your AI coach answers faster than this page does, and it's nicer than the FAQ.
Runna is running only. Fitbod is a daily generator with no real arc. Strava tracks what you already did — it doesn't coach. exrsz is the actual coach across all of it. One plan instead of three apps arguing with each other.
Stop following someone else's plan. Get one that's actually yours.
