Blocking your phone at the gym and on runs
The gym is the case where the phone has a real job. Music, a timer, a programme to follow, a set to log. You cannot simply leave it in the car.
It is also where rest periods create a perfectly shaped hole: sixty to ninety seconds of nothing to do, a phone already in your hand because you just logged a set. A ninety-second rest becomes four minutes and the session runs an hour long or gets cut short.
What to block, and where the key goes
Four decisions. The last one is the mechanism rather than a flourish: unlocking means holding your phone against the key, so put it somewhere you have to walk to.
Block the feeds, not the tools
You pick what to block, so put every feed and messaging app on the list. Music, your timer and your training log stay open because you never pick them, and calls always get through. Anything else you leave off the list is a negotiation with yourself between sets, at the exact moment you are most bored and least invested.
Lock before you walk in, not at the first set
The changing room is where the scroll starts. Lock in the lift, in the car park, at the door — one tap, no key needed and no signal needed, which is the whole reason locking has no gate on it.
The key goes in the locker or the car
This is the one use case where the distance is naturally solved: the key stays with your bag, and the bag is already somewhere you cannot casually get to mid-session. One thing to check on the first visit is where the lockers are. If they are beside the rack, fetching the key is a few steps rather than a walk — use the car instead.
For runs, take the phone and leave the key
You want the phone for safety and for tracking. Leave the key at home and unlocking means running back to it, so the phone becomes exactly one thing — a tracker that can still take and make calls — for the whole run, whatever you decide about it at kilometre four.

The car park is a walk by construction, which is what you wanted from the locker.
Take the phone for safety and tracking; leave the key behind, and unlocking means running back to it.
The failure mode: the rest period
Nothing about your intent changes between sets. What changes is that you have ninety seconds, the phone is already unlocked in your hand because you logged the last set, and the feed is one swipe away. Blocking is more effective here than in almost any other use case precisely because the trigger is so mechanical: remove the swipe and the rest period goes back to being ninety seconds.
Doesn't blocking get in the way of my programme?
Not if you leave the app you follow it in off the block list. The mode is meant to leave your training tools completely untouched — if it does not, it is set up wrong. The purpose is to make the phone able to do only the thing you took it out for.
Questions about training
How do I stop scrolling between sets?
Block the feeds for the length of the session and leave your music, timer and training log unblocked. The behaviour is mechanical rather than motivated — you scroll because the phone is already in your hand and the rest is empty — so removing the route works better here than resolve does.
Can I still use Spotify and my running app?
Yes. Blocking is per-app and you pick what to block, so anything you rely on during training simply stays off the list.
What about safety on a run?
Take the phone — calls always get through a block. Leave the key at home instead: that gets you a phone that can call for help and open none of the apps you blocked, which is the right shape for a run.
Where do I put the key at a gym?
A locker is the obvious answer and usually the right one. If your gym has none, the car is fine — the point is that the key is a walk away rather than in the bag at your feet, which is a reach and therefore no barrier at all.
Will a block interrupt my music mid-set?
Not if your music app is off the block list. You choose what to block before the session starts, and anything you did not pick keeps working exactly as it did, audio included. The apps you did pick simply do not open.

Putting your phone away for family time, and keeping it away: three apps, two hours, and why a phone face-down on the table can still cost you something.
Read the setupIf what you want is the method rather than the situation, the guides go deeper, and how it works covers the part that makes all of this hold — unlocking means holding your phone against the key, so where you leave it is the whole design.

A mode you configure once and stop thinking about.
Locking is one tap and never needs the key. Unlocking means walking to wherever you decided to leave it, back when you were thinking clearly, and holding your phone against it. The app is free; the key is the one-time buy.
