Discreet Desk Exercises for an Open-Plan Office While Claude Code Runs

Most advice about moving during agent runs quietly assumes you work from home. Drop and do ten push-ups while Claude Code refactors the auth module; a set of squats while Codex runs the test suite. That is fine in a spare bedroom. In an open-plan office with forty people, a glass meeting room behind you and a sales team that notices everything, it is a different proposition. Nobody wants to be the person doing lunges by the printer, and so the movement break that was going to happen never does, and the eight-hour sit wins again.

This post is the open-plan version of our desk exercises for programmers and the follow-up on sitting too long and posture: the same idea, that every agent run is a free gap, applied to a room where you would rather not be watched. It sorts the moves into three tiers by how visible they are, matches each tier to how long a run usually takes, and is honest about the etiquette and about where an app like NotchFit does and does not help.

The social problem, stated plainly

The obstacle is not the exercise; it is the audience. Three things make office movement awkward: it is visible, it can be audible, and it can leave you sweaty in a room without a shower. The fix is not to stop caring what colleagues think, which is advice nobody follows, but to pick moves that clear all three bars for the situation you are in. A seated calf raise under the desk clears every one. A set of burpees clears none. Most useful moves sit in between, and the trick is knowing which to reach for when the terminal says Claude has started a task that will take a while.

Tier one: invisible at the desk

These can be done while apparently reading the agent’s output. Nobody across the desk can tell, and they fit the one- to three-minute runs that make up most of a day.

• Seated glute squeezes. Squeeze hard for five seconds, release, ten times. Wakes up muscles that go to sleep in a chair and nobody will ever know.
• Calf raises under the desk. Heels up, hold two seconds, down. Fifteen to twenty. These move blood out of the lower legs, which is the whole point of breaking up sitting.
• Ankle circles. Ten each way, each foot. Trivial, silent, and good for anyone whose ankles feel stiff by four in the afternoon.
• Shoulder blade squeezes. Pull the shoulder blades together and down, hold five seconds, ten times. The direct antidote to the rounded-forward hunch of reading a terminal.
• Chin tucks. Slide the head straight back as if making a double chin, hold three seconds, ten times. Counteracts forward head posture; looks like you are thinking.
• Wrist and forearm stretches. Arm out, palm up, gently pull the fingers back with the other hand for twenty seconds; then palm down. Typing-adjacent and completely unremarkable.
• Seated spinal twist. Hand on the opposite knee, turn gently, hold twenty seconds each side. Reads as stretching in your chair, which everyone does.
• Isometric core brace. Sit tall, brace as if about to be nudged, hold ten seconds, breathe, repeat five times. Invisible and surprisingly tiring.

Tier two: low-key standing moves

Standing up at your desk is normal in any office that has sit-stand desks or a water cooler. Use that cover for moves that are obviously movement if someone stares, but not odd enough to be noticed. These suit the five- to ten-minute runs: a build, a test suite, a multi-file refactor.

• Standing calf raises while you wait for the kettle or the coffee machine. Twenty, slow.
• Hip hinges. Feet hip-width, soft knees, push the hips back with a flat back as if closing a drawer with your backside, stand tall. Ten to fifteen. Looks like stretching your back, which it is.
• Sit-to-stand squats. Lower yourself to the chair slowly, hover a centimetre above it, stand. Eight to ten. Every office contains people standing up and sitting down; nobody counts.
• Doorframe chest stretch on the way to the kitchen: forearms on either side of a doorway, lean through gently for twenty seconds. Pick a doorway people do not need to walk through.

Tier three: go somewhere

For the long runs, the twenty-minute migration or the agent working through a backlog of lint errors, leave the desk. Take the stairs two floors down and back. Walk to the far printer, or to the kitchen on another floor. If there is a free meeting room, five minutes of proper stretching with the door closed is the best movement you will get all day, and a meeting room with the blinds down is the one place in an open-plan office where the social cost drops to zero. If your office has a bike store or a quiet stairwell, that works too.

Etiquette: noise, smell and timing

Three rules keep this sustainable. First, nothing that makes noise: no jumping, no dropping into a plank beside someone on a call, and if an app speaks to you, mute it. Second, nothing that makes you sweat before a meeting; tier three is for the morning or the end of the day, not the half hour before a customer demo. Third, read the room. Some teams will join in and some will not, and the quiet version is the one that survives a room that does not. If you want company, say what you are doing once, lightly, and let people opt in.

Matching the tier to the run

The point of tying the move to the run is that you stop deciding. The agent starting a task is the cue; the length of the task picks the tier. Over a day of twenty or thirty runs that adds up to far more movement than one gym session you were going to skip anyway.

A quiet week

If you like structure: Monday and Thursday are lower-body days (calf raises, hip hinges, sit-to-stand squats, stairs). Tuesday and Friday are upper-body and posture days (shoulder blade squeezes, chin tucks, wrist stretches, doorframe stretch). Wednesday is the long-walk day, where every run over ten minutes means a lap of the building. None of it requires equipment, a change of clothes or anyone noticing. The companion post on standing desk exercises has more for the days you are at a raised desk.

Where NotchFit fits, and where it does not

NotchFit is a $20 one-time macOS menu bar and notch app for developers who use Claude Code or OpenAI Codex CLI. When your agent starts a task, the MacBook notch expands into a panel with a guided animated exercise on the left and the agent’s live progress on the right, and it tells you when the agent is done or needs permission. In an office, three details matter. The library is 239 animated exercises, 198 of them photo animations of real athletes and about forty illustrated moves, so there is plenty to choose from that does not involve jumping. The weekly plan is written by Claude Code (/notchfit:plan) or Codex ($notchfit-plan) after asking about your goal, equipment, fitness level, injuries, days per week and minutes per day, which means you can ask for a plan built from quiet, seated or standing moves and no equipment; there is no dedicated office mode, but the plan prompt is where you steer it. And the optional spoken alerts use on-device macOS voices with a mute button: mute them, and the notch stays silent while the rep ring counts down.

The rest of the design suits a shared room. Sets start only when you tap Start set, so nothing launches while a colleague is at your desk, and a “Claude is done” alert that arrives mid-set waits until the set ends. There are streaks, a history heatmap and confetti when you finish, an offline quick-plan generator if you do not want the AI to write the plan, and a Hide workout toggle that turns the notch into a pure status panel for days when movement is off the table. It runs locally on your Mac with no account, no telemetry and no microphone, the hooks run asynchronously so the agent is never slowed, and it needs macOS 14 or later on Apple Silicon or Intel; Macs without a notch get a top-centre pill instead. It is sold on Whop as a signed and notarized DMG, with no trial and no license key.

Where it does not help: it cannot make the office less open. The animation on the notch is visible to anyone standing behind you, so the panel itself is a small giveaway; if that bothers you, the quietest tier-one moves need no app at all, and the Hide workout toggle exists for exactly that mood.

When not to do any of this

If you have an injury, pain that changes with movement, or a condition your doctor has given you rules for, follow those rules and not a blog post. If your workplace has policies about exercising at desks, or your role involves being camera-ready at short notice, pick the invisible tier and leave it there. NotchFit is a workout guide, not medical advice, and the moves above are the ordinary, low-load ones that most people can do; the moment one of them hurts, stop.
