I’ve twisted up my fingers skateboarding. Been underwater in the rapids outside Munich. Been put to the ground with electricity. Fallen off a roof replacing shingles. Gotten chemical poisoning while casting urethane at work.

But I think the worst thing I’ve done for my health in the last ten years is working at a computer every single day.

Last week I did seven hours of work one day without moving. My hands moved but the rest of me was rather statuesque, either sitting or standing at my desk.

My current client work has me spending a lot of time doing agentic development. I’m researching, designing, building, and reviewing work with agents.

But it’s not like I’m now some 1930s manager in my leather office chair, cigar smoke billowing around my office as I call out orders to my new AI friends.

That idea that AI frees up time for other things — kinda not true.
I love creative problem solving that’s what got me into design and building in the first place. So now that I get to see what i’m building so quickly, I lean in more not less. I’m sucked deeper into the work— ‘cause it’s fun to see what you’re making come to life.
But this comes with its own problems

Building with agents can kinda feel like scrolling through TikTok.

It gives you a hit every few minutes so you keep at it. Only with agents you're building something, not molding into your sofa scrolling social media.

We read about the AI labs saying AI would free up time. But i don’t recall anyone mentioned it would also make the work harder to put down. This is addictive.

My colleague and I were catching ourselves becoming aging statues that were directing AI. So we made a rule: every pull request — basically you sliding your piece of work to the middle and saying “I’m done, someone check this”. We have to do 10 reps of an exercise. Push-ups, sit-ups, you name it.

It got fun. We spent the day co working on a call doing excerise and building.
The day was filled with “don’t forget your push-ups!” and “Damn I owe 20!”

It was so fun, that of course I coded it.
I built a Command line interface(CLI) app that runs in a Claude skill to prompt us into moving. Something to work with Claude Code because… why not?

Your first PR of the day you choose the exercises

My thinking is if we are going to be pushing and pulling (code) all day, when not do the same with some physical activity?

Last Wednesday I did 85 push-ups while working. The day before, I hadn’t moved more than to refill my coffee and use the bathroom.

I’m spending time to build something really high quality for clients but unlike projects in the past, I also want to get really fit in the process.

What I built is very simple.

There’s a two step step-up where it asks It asks if you have any equipment: weights, pull-up bar, bands, etc. and permission to watch for pull requests.

That’s it — it runs silently in the background. Every time you create a pull request with Claude Code, it prompts you with an exercise and a suggested rep count, asks “How did you do?”, and logs everything so you can check in throughout the week.

it’ll log all of the exercises you’ve done so that you can ask it throughout the week how much exercise you’ve been doing.

Is this a personal trainer and going to give you a well-balanced workout? No. Is this fun and going to get you moving? 100%

I’d love for you to try it.

If you want to use pr-fitness, I’ve made this all open source.

The normal and classic way.
Open your terminal and run:
npm install -g pr-fitness

then
pr-fitness setup

Or Lazy tell an agent way:
Paste the Github link below into the terminal when you have Claude Code running. Tell it you want to install and set up pr-fitness. https://github.com/DomGme/pr-fitness. While you’re at it include the link to this essay for more context.

P.S. If you know anybody who’d be interested in using pr-fitness. Or who you think would enjoy what I write and make, please send this essay to them. I’d love to meet more of you.
