1. Not Medical Advice

The content and calculators on ORM Calc are for informational and educational purposes only. They are not intended to be a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or another qualified health provider with any questions you may have regarding a medical condition or before starting a new exercise program. Never disregard professional medical advice or delay in seeking it because of something you have read on this website.

2. Assumption of Risk & Injury

Strength training, powerlifting, and lifting heavy weights carry inherent risks, including the risk of serious injury or death. If you choose to test your one-rep max, attempt a new PR, or perform any lifts suggested by the site, you do so entirely at your own risk.

Always use a spotter, use safety pins in a squat rack, and lift within your physical capabilities. ORM Calc is not responsible for any injuries sustained while training.

3. Accuracy of Calculations

While we have taken extreme care to implement accurate formulas (Epley, Brzycki, Wilks 2020, IPF GL, etc.), all calculators are mathematical estimates.

• 1RM Estimates: 1RM calculators provide an estimate based on submaximal reps. They are not a substitute for a tested, supervised 1RM.
• Competition Rules: Federation rules, weight classes, and scoring coefficients change over time. Always verify your calculations against the official rulebook of your specific federation (e.g., the IPF, USAPL, or USPA) before competing or submitting a record.

4. External Links Disclaimer

The site may contain links to external websites that are not provided or maintained by ORM Calc. We do not guarantee the accuracy, relevance, or completeness of any information on these external websites.

5. No Doctor-Patient Relationship

Use of this website does not establish a doctor-patient relationship or a coach-athlete relationship. The creators of this site are providing software tools, not professional services.
