How we verify

Evidence: Screenshots or logsThe source shows screenshots, a transcript or the agent's output.

Outcome

Claude Code read four weeks of the poster's workout logs, found where lifts stalled, wrote the next training cycle with a reason for each starting weight, loaded the routines into the tracking app, and noted where the app would suggest the wrong weight.

Agent

Claude Code

The source didn't share its exact prompt, so we wrote this from what it describes.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Look at my last four weeks of workouts, find where I've stalled, and write my next training cycle.

Check with me first: What's my main goal right now, for example strength or muscle?

What I'll give you:
- My workout logs for the last few weeks
- My current plan

Rules:
- Point out the exercises where I've stalled, with the numbers.
- Give a reason for each new starting weight.
- Flag anything my tracking app might get wrong.
- If something is missing or unclear, ask me instead of guessing.
- This is a training plan, not medical advice.

Output: The new cycle, reasons for each weight, and notes on what to watch.

You'll know it worked when: I have a clear plan that explains why each weight was chosen.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Review four weeks of workout logs, find stalls and write my next training cycle.

Quick check first: tell me if anything below is missing or unclear.

Inputs (fill in or confirm):
- Workout logs
- Current plan
- Main goal
- Injuries or limits
- Days per week and session length

Rules:
- Show stalled lifts with numbers.
- Explain likely causes.
- Write a 4-week cycle with sets, reps, load and progression.
- Include deload rules.
- Use the logs' actual weights and reps; don't assume a 1RM unless you show the formula.
- Keep exercise swaps minimal and explain each one.
- Add a simple way to log the new cycle so stalls show up early.
- Note warning signs to stop or see a professional (pain, not just fatigue).
- Keep weekly volume changes gradual.

If you get stuck: If data is missing, ask. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Check the plan fits my available days.

Output: Analysis and the new cycle.

Done when: I have a clear plan addressing stalls.
