The dark horse of strength training

Your workout,
in your ears.

Hear two sets

Gym Jockey isn’t another logger with a timer bolted on. It starts from one observation: the gym is no place to read, and under the bar is no place to think. So you build the workout beforehand, and at the gym the app talks you through it set by set, with your reps, your plates and your own cues. Between sets you hear your playlist; during the set, the best part of the song you picked for that lift.

For iPhone · free during the TestFlight beta. What's TestFlight?

Two sets, as you'll hear them.

Demo, stripped down to a single exercise. Imagine yourself at the bench with your headphones on and your phone on the floor beside you.

Why it exists

Gym Jockey was born out of six frustrations. You may recognize them.

Try it: drag the knobs, or use the arrow buttons (‹ ›), to find the moment, then Play Clip.

01 / Music

You name the place.
We name the time.

Gym Jockey starts the clip you chose the moment you start the lift, so the music hits when you do — not three minutes into the track. And if what you need isn’t music, use that instead: your own voice, a cadence, whatever works.

  • Heavy squat? Save the killer 32 seconds that get you psyched.
  • High-rep set? Pick something relentless.
  • Need cadence? Record yourself: “And up! 3, 2, 1, hold…”
  • No idea? Browse what other lifters swear by.

Clips are optional. Without them, the app still talks you through every set.

How clips work

You always know where you are.

02 / Orientation

You focus on the lift.
We focus on the rest.

You shouldn’t need a screen to know where you are. Under the bar you’re locked in: you know what you’re chasing, and your song is already pumping. Between sets you can drift off. Gym Jockey keeps your place, and when it’s time, it brings you back and tells you what’s next. Nothing to watch. Nothing to hunt for. Nothing to remember.

  • Missed something? Tap Back on your headphones and hear it again.
  • Still not sure? A glance at the Watch or the phone says the same thing.
A set, start to finish

Good intentions by design.

The note library for an exercise, with the cap on how many you hear at once A note set to be spoken after the first set, once a month: “Record yourself from the side for this next set”

03 / Notes

You write the cue cards.
We deal them.

Maybe you want one reminder, now and then. Maybe you’ve broken an exercise down properly and there’s a lot to say. Write as much as you like: Gym Jockey feeds it back on your terms — in your own voice, if you want — and never more at once than you asked for.

  • The machine you can never remember how to set up.
  • That last set of deadlifts, when your form starts to go.
  • The mobility work you promise yourself you’ll do while resting.
  • And if you’re the one who forgets to wipe the bench — Gym Jockey is happy to mention it.
How notes are configured

The clock doesn't know how you feel.

One exercise, four sets, four rests
  1. Set 12:00
  2. Set 22:30
  3. Set 33:00
  4. Set 4♥under 130 bpm, then 30 s more, typically between 2:00 and 5:00

In your ears: tones as the rest runs down, subtle at first, more insistent near the end

04 / Rest

We mind the gate.
You catch your breath.

Rest has two jobs, and counting down the seconds is only one of them. You want enough rest — the right amount for this set, not the average of five. And you want to be under the bar when it’s time, not just starting to notice. So you set the rest, and Gym Jockey counts it down in your ears: tones, subtle at first, more insistent near the end. You’re rested and ready to roll straight into the next set. Add it up over a workout and it’s minutes back — without cutting a single rest short.

  • Same rest every set, if that’s what you want. Nothing wrong with the classic.
  • Or give each set what it actually needs — the fifth one isn’t the first.
  • Or stop guessing: rest until your heart says you’re ready, read from your Apple Watch or a Bluetooth chest strap.
Heart-rate rest

Faster than you can forget it.

The routine screen with two memos waiting at the top The same memo, recorded from the Watch Recording a memo mid-session: tap and hold the mic, speak

05 / Memos

We hold the thought.
You hold the bar.

The thought arrives mid-set and it’s gone by the next one. Writing it down means unlocking the phone, finding somewhere to put it, typing with chalk on your fingers — and then remembering, days later, that you wrote it at all. So just say it, while it’s still hot: the mic is right there, on the phone and the Watch. Tap and hold, get it out, get back under the bar. You don’t have to remember to go back to it. It comes back to you.

  • That grip felt wrong. Say it now, fix the exercise later.
  • The bar moved too easily. Say it now, add weight next time.
  • Shoulder twinged on the third rep. Say it now, decide later.
  • It comes back before and after every session, until you deal with it.
Memos, on phone and Watch

Tracking is the effort. This is the payoff.

Recovery time and heart-rate range, session by session Set-level insights: set 1 flat while set 4 climbs Estimated one-rep max for the average and sets 3 and 4, with sleep and the cut drawn beneath

06 / Tracking

You track it.
We connect it.

Tracking is the easy part. Tying it to what you lifted is the hard part. Here, whatever you choose to track is drawn against your sets, so you can see why it happened, not only what happened.

  • Rough month? See whether it lines up with the cut, the cold or the travel.
  • Sleeping badly? Watch what it does to your numbers, week by week.
  • Only watching the average? Open any exercise set by set — the first set can stall while the last one climbs, and the average hides both.
  • Changed programs? The line through the chart says when.
  • Years of history elsewhere? Bring it with you and look before you lift.

How you run it

More time in the zone.
Less time on your phone.

If the app talks to you through your headphones, the buttons on those headphones are the natural way to answer. Everything else is for the moments three buttons aren't enough, and the screen comes last.

Headphones
Play, back, forward. Back replays your targets when you've already forgotten them. Forward ends a rest that's dragging on. Most sets, that's all you touch.
Watch
When you need more than three buttons: log a set with the crown, skip an exercise, mute the music, hold the mic for a memo. The next-set call lands on your wrist.
Siri
When your hands are full: the reps you did, how hard it felt, play and pause — said, not typed.
iPhone
Everything the Watch does, for when you don't wear one or want a bigger screen. If the rack is taken, Up Next lets you start another exercise now and come back to this one after.
Lock Screen
In a pinch: the countdown and the controls, without unlocking the phone.

The workout

You've heard two sets. A real workout is longer: the check-in before it, the wrap-up after it, and everything the app does in between that you didn't hear.

Walk through a whole workout

For coaches

Your voice in your clients' ears — cues and notes spoken mid-set, at the moment they're needed. And their sessions come back to you: every set they logged, their check-ins, their memos, in your own reports.
