Terms of Use

1. Acceptance of Terms

By using this Site, you confirm that you are at least 13 years old and are legally capable of entering into a binding agreement. If you are using the Site on behalf of an organization, you confirm that you have the authority to bind that organization to these Terms.

2. Not Medical or Professional Advice

The calculators, charts, and articles on this Site are provided for informational and educational purposes only. Nothing on this Site constitutes medical, health, or professional training advice. Estimating your one rep max, attempting heavy or maximal lifts, and following any training program carries inherent physical risk, including the risk of injury.

Always consult a qualified physician before starting any exercise program, and consider working with a certified coach when attempting near-maximal or maximal lifts. You are solely responsible for how you use the information and estimates provided on this Site, and for assessing your own readiness and technique before any heavy attempt.

3. Accuracy of Calculations

Our tools use established strength-estimation formulas, including Epley, Brzycki, and Lombardi, to generate an estimated one rep max based on the weight, reps, and effort level you provide. These are mathematical estimates, not guarantees. Actual strength performance depends on many factors — technique, fatigue, recovery, and individual variation — that no formula can fully account for. We make no warranty that any result generated by this Site will match your true maximal lift.

4. Permitted Use

You may use this Site for personal, non-commercial purposes, including calculating training loads, tracking strength progress, and reading our guides. You agree not to:

• Copy, scrape, republish, or redistribute our content, calculators, or underlying code without written permission
• Reverse-engineer, decompile, or attempt to extract the source logic of our calculation tools
• Use automated systems (bots, scrapers) to access the Site at scale
• Use the Site in any way that could damage, disable, or impair its functionality
• Misrepresent your affiliation with this Site or its content

All content on this Site — including text, guides, charts, graphics, calculator logic, and design — is the property of OneRepMaxCalculatorz.com unless otherwise stated, and is protected by applicable copyright and intellectual property laws. You may reference or link to our content with proper attribution, but reproduction of substantial portions without permission is not allowed.

6. Third-Party Links and Advertising

This Site may display advertisements and links to third-party websites through partners such as Google AdSense.

Visiting those sites is at your own discretion and risk.
