# Heatsy

> Heatsy is a strength-training log that shows you what you actually trained. Not a number. Not a chart. Your body. This site is its public exercise catalog: for every exercise there are names and synonyms, body region, muscles by role (main, helping, holding), equipment and step-by-step technique with cues and common mistakes.

## About the product

- Heatsy is an iPhone app (iOS 27). There is no web version; this website is the exercise catalog, support and legal pages.
- Every logged set heats up the muscles it worked on a 3D anatomical body, male or female. Plans are built from rules for exercise selection, volume and progression.
- AI is optional and asks for consent first; the user's name and email are never sent to AI services.
- The app requires a subscription (yearly with a free trial for new subscribers, or monthly); the price is shown in the app before purchase.
- Made by Heatsy. Data is stored on servers in the EU. Contact: support@heatsy.app
