How I upped my gym game with Claude Code and you can too
I’m training in the gym for 7 years now and was regularly missing a personal advisor I could always reach out to. Trainers had limited capacity, I didn’t find proper nutritionist and searching through youtube (and validating what was said) was tiresome. Then I used something different.
🤖I started playing with Claude Code agents since last year and built my own fitness advisor which is also a skill in my Claude Code. I use it regularly since few months now and it helped me survive through injury and plan leaner growth, among many.
🔎 When iterating on it I focused on:
* Science based knowledge - it uses peer reviewed papers and tells you when data is not sufficient to answer your question. It also gives you the research details and a link (if available). It skips youtube, reddit and other noise. Only proven science.
* Connecting with my app of choice (Hevy in this case but also supports others) in order not to copy-paste data I already have.
* Reading my measurements, pdf’s from Tanita, Inbody or other body scan devices to know where I am and adjusting training.
* Structure - it’s well structured in terms of folders and commands I can use.
* Always checking my background and history before giving answer so all recommendations are always tailor-made.
🏃🏼💨So, what can it do?
-> When I got an injury it helped me which exercises to avoid so I could keep on training muscle groups that were safe.
-> It adjusted my nutrition according to my age, weight and recent measurements.
-> It debunked lots of myths based on proven scientific knowledge.
-> It helped me recover post-illness so my body and diet could adjust slowly to training without a negative effect on my organism.
Of course, it can make mistakes. This is not a bulletproof solution and consulting a professional trainer or dietician is a solid choice. I have trained for a a couple of years with a personal trainer and this does not substitute for a professional support. That said, it helps in steering things in the right direction and on the spot assistance very well.
❓Why Claude Code and not a standalone app?
- Claude Code does not teach Anthropic models on what you use it for.
- Everything is on your local drive and in your custody in .md format - no vendor lockdown.
- Claude Code always asks you what to do so it won’t mess anything up without your permission.
I update it regularly, it’s free to use and you can find it on my GitHub. Install it, use "/fitness setup" for the first time and it will guide you through the rest. 🧘🏼♂️
It helped me a ton, maybe it will help you.💪 DM me with your thoughts once you tried.
