Can agents run this deterministically?

Yes. The engine is a pure function with zero randomness. Given identical inputs, every run produces byte-identical JSON output suitable for automated pipelines.

How to use it

Open Strength Standards Calculator and enter your current baseline accurately.
Adjust one variable at a time so changes are easy to interpret.
Review the headline output first, then inspect supporting metrics.
Run at least one conservative and one aggressive scenario.
Use outputs to set your next training or nutrition action for the week.
Save or share this setup if you want to revisit it later, then check one easier and one harder version before you change your plan.

Agent playbook

Resolve Strength Standards Calculator from /agent-tools.json and open its contract before execution.
Validate inputs against the contract schema instead of scraping labels from the page UI.
Open the browser page only when a person wants to review charts, assumptions, or related tools.

Agent FAQ

Should ChatGPT, Claude, or another agent click through the UI?

No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.

When do tools show Quick and Advanced?

Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.

When should an agent still open the browser page?

Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.

Questions people usually ask

What are the strength standards based on?

Standards use widely published bodyweight-ratio benchmarks from strength training communities, normalized across Beginner to Elite levels.

Should I enter my actual 1RM or estimated?

Either works. If you don't test true 1RMs, use our One-Rep Max Calculator to estimate from a working set.

Why are male and female standards different?

Biological differences in muscle mass distribution mean different absolute strength benchmarks. Both scales use the same Beginner-to-Elite progression.

Is this tool free and private to use?

Yes. All calculations run locally in your browser. No data is sent to any server, no account is required, and no cookies are set.
