TL;DR
What did Veselin Stoyanov (@st0yanov) use ChatGPT for?
Someone who has logged every exercise, set and rest period for three years connected the Caliber workout app to ChatGPT and asked about patterns in their history, and came away with a concrete plan to break some plateaus. They called the insights impressive: things they had not noticed started to make sense, and they now have a concrete plan to try.
What they did
For three years they have logged every workout in the Caliber app, down to each set and the rest between sets, but were stuck on certain exercises. When Caliber released a way to connect to ChatGPT, they hooked it up and asked about their training history, looking for patterns, inefficiencies and reasons their progress had stalled.
How it went
They called the insights impressive: things they had not noticed started to make sense, and they now have a concrete plan to try.
Worth knowing
- This only works if you have been logging consistently and your app connects to ChatGPT or lets you export your data. ChatGPT's training advice is general, so check big changes with a coach or doctor if you have an injury.
- Price check: ChatGPT: free plan; Go: US$8/month (checked Nov 1, 2026).

Here is my workout history. Look at the exercises where my weights or reps have not improved in the last few months. For each one, point out patterns in my sets, rest times and how often I train it, give two likely reasons I'm stuck, and suggest one change to try for the next four weeks.
