Terms of use
Updated 26 October 2026
What SlowStrong is
SlowStrong is a fitness app with home workouts, gym programs, a Heavy Duty training program, a logbook, nutrition targets and an AI coach. By using the app, or by creating an account, you agree to these terms and to the privacy notice. If you do not agree, please do not use the app.
Your health and safety
The app is general fitness and nutrition information, not medical advice, and it is not a substitute for a doctor, physiotherapist or dietitian. Talk to a doctor before you start or change an exercise or eating plan, especially if you are over 40, pregnant, have a health condition, an injury or take medication. Heavy Duty training asks for one set taken to true muscular failure; stop any exercise that causes pain, dizziness or loss of control. You exercise at your own risk and are responsible for choosing weights and movements that are safe for you.
The AI coach and meal plans
Answers from the AI coach and AI meal plans are generated automatically. They can be wrong, and calorie and nutrient numbers are estimates. Check food labels and do not rely on the AI for medical decisions. Use of the AI features is limited per minute and per day to keep the service available for everyone.
Accounts
You can use the app as a guest, with your progress saved on your device only, or create an account to keep it on every device. Keep your sign-in details to yourself and give accurate information. You are responsible for what happens under your account. You may stop using the app at any time and can ask for your account data to be removed (see the privacy notice).
Free beta and any future prices
While the app is in beta, all programs are free and nothing is charged. Features can change, move or be removed during the beta. If paid features are introduced, the price, what is included and how to cancel will be shown clearly before you pay, and nothing is charged without your action.
Using the app fairly
Please do not misuse the app: do not try to break, overload or get around its limits or security, do not use it to harm others, and do not copy or resell its programs or content. We may limit or stop access to protect the service or other users.
Content and your data
The programs, text, images and design of the app belong to SlowStrong or its licensors and are provided for your personal use. The workouts, measurements, foods and notes you enter stay yours; you allow the app to store and process them to provide the service, as the privacy notice describes.
No affiliation
The Heavy Duty program is based on the published training principles of Mike Mentzer. SlowStrong is not affiliated with or endorsed by Mike Mentzer or his estate.
Availability and changes
The app is provided as it is, without a promise that it will always be available or error free. We may update it and these terms; the date above shows the latest version, and continuing to use the app means you accept the update. To the extent the law allows, SlowStrong is not responsible for injury, loss or damage that results from using the app or relying on its information. Nothing in these terms limits any rights you have under the law that cannot be limited.
