Disclaimer

Medical Disclaimer

The 1RM Calculator and its results are not intended to diagnose, treat, cure, or prevent any disease or health condition. Before beginning any strength training program or attempting heavy lifts, you should:

• Consult with a qualified physician or healthcare provider
• Obtain medical clearance if you have pre-existing health conditions
• Discuss any medications that may affect physical performance
• Be aware of cardiovascular, joint, and musculoskeletal limitations

Estimation Accuracy

All calculations provided by this tool are estimates based on mathematical formulas. Your actual one-rep max may differ significantly from estimated values due to:

• Individual biomechanics and leverages
• Training experience and technique proficiency
• Current recovery status and accumulated fatigue
• Psychological factors and confidence under heavy loads
• Equipment differences (bars, plates, machines)

Safety Warnings

Strength training carries inherent risks including:

• Muscle strains, tears, and overuse injuries
• Joint and connective tissue damage
• Cardiovascular stress and blood pressure spikes
• Acute injuries from dropped weights or loss of control
• Chronic injuries from poor form or overtraining

Always use proper form, appropriate warm-up protocols, qualified spotters, and safety equipment when attempting heavy lifts.

Professional Guidance

We strongly recommend working with qualified professionals when pursuing strength training goals:

• Certified strength and conditioning specialists (CSCS)
• Certified personal trainers with strength training experience
• Experienced powerlifting or Olympic weightlifting coaches
• Sports medicine physicians and physical therapists

No Liability

By using this calculator, you acknowledge that:

• You use this tool entirely at your own risk and discretion
• We are not liable for any injuries, damages, or losses resulting from use of this calculator
• You are solely responsible for determining appropriate weights and training loads
• Results should be verified through proper training and supervised testing

Not a Substitute for Testing

While this calculator provides useful estimates, it does not replace proper 1RM testing protocols conducted under safe, supervised conditions with appropriate warm-up, spotters, and safety equipment.

Age Considerations

Maximum strength testing is generally not recommended for individuals under 18 or over 65 without specific medical clearance and professional supervision. Youth athletes and older adults should focus on sub-maximal training with appropriate progressions.

Updates and Changes

This disclaimer may be updated periodically. Continued use of the calculator constitutes acceptance of any changes to this disclaimer.
