Terms of Service
Free strength calculators. No account required.
This release offers free calculators only. Accounts, cloud storage, subscriptions and paid training plans are not available.
Results are estimates for general training information, not medical advice. Use safety equipment and seek qualified guidance before attempting heavy lifts.
Use the tools lawfully. Do not disrupt the service, bypass security controls or misrepresent calculated results as verified performance. Availability and accuracy are not guaranteed; nothing here excludes rights or liabilities that applicable law does not allow us to exclude.
