On Deck FitnessOn Deck Fitness
Your next workout. No decisions.
On Deck Fitness is a workout app for iPhone and Apple Watch that programs your training for you. It knows what equipment you have, what injuries you’re working around, and whether you want to lean toward strength, conditioning, or somewhere in between — then it hands you your next complete workout, scaled to your fitness level and how recovered you are. Hit start, and the built-in timer runs the rounds, reps, and rest so you never have to watch the clock.
The mystery box
No endless program browsing, no planning paralysis. One workout is on deck at a time — and you can’t peek ahead until you’ve earned it.
Built around your body
Tell it about your injuries and it programs around them. A recovery engine tracks muscle-group fatigue behind the scenes, enforces cooldowns, and picks work your body is actually ready for.
Your equipment, your scale
Register what you own — a full rack or a single kettlebell. Every workout is built from your inventory, and early calibration workouts tune it to your real capacity.
Strength, conditioning, or in between
Set the dial toward getting stronger, building your conditioning, or a balance of both. The programming follows your goal, not a one-size-fits-all template.
Just hit start
The whole workout is loaded into a built-in timer — rounds, reps, rest periods, all of it. Press start and you’re off and running. No stopwatch, no counting in your head.
The Mercy Rule
Having a rough day? Scale a workout down without shame — the engine adjusts and keeps you moving instead of quitting.
How it works
Vibe Check
A quick, funny onboarding that captures your stats, equipment, injuries, where you want to sit between strength and conditioning, and how you like to suffer.
Calibrate
Your first workouts are calibration probes that measure where you actually are — not where you say you are.
Open the box
Your next workout appears, fully programmed. Hit start, let the timer run the rounds and rest, and the engine percolates the next one while you recover.
Repeat
Fatigue-aware programming keeps every session productive — and every next box a surprise.
About On Deck Fitness
On Deck Fitness is a fitness application for iPhone and Apple Watch, published by Kickstep Inc. Its purpose is to take the planning and decision-making out of exercise: rather than browsing workout programs or building your own routine, you are given your next complete workout, chosen and scaled for you automatically.
You register the exercise equipment you own, note any injuries you are working around, choose whether to bias your training toward strength, conditioning, or a balance of the two, and complete a few short calibration workouts so the app can measure your starting capacity. From then on, a recovery-aware engine tracks which muscle groups you have already fatigued, enforces rest between hard sessions, and selects the next workout your body is ready for. Each workout is delivered inside a built-in timer that tracks rounds, reps, and rest periods, so you press start and follow along. If a workout is too much on a given day, the Mercy Rule scales it down instead of leaving you to quit.
Accounts and sign-in
On Deck Fitness uses an account so that your workout history, calibration results, and equipment profile stay in sync between your iPhone and Apple Watch. You can sign up with an email address, or sign in with Apple or Google. When you sign in with Google, we receive only the account identifier and email address that Google shares with us, and we use them solely to create and sign you in to your On Deck Fitness account. We do not use that information for advertising, and we do not sell it.
Your data
With your permission, the app also reads and writes workout data through Apple HealthKit to record your sessions and estimate recovery. Our use of artificial intelligence is deliberately narrow: it is limited to natural-language translation in our backend API, running on user-agnostic models inside our own private cloud — never used to advertise to you, and never trained on your personal data. Our Privacy Policy describes in full what we collect and how it is handled, and our Terms of Service covers the terms of use. You can delete your account and its associated data at any time from within the app, or by contacting us through our Support page.
