Terms of Service
Last updated: July 26, 2026
Introduction
Welcome to GymRec (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at gymrec.com and all associated calculators, guides, and services (collectively, the “Service”).
By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of them, please do not use the Service.
Acceptance of Terms
By accessing, browsing, or using GymRec, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated by reference.
We may update these Terms at any time. Your continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
Estimates for Planning — Not Professional Advice
GymRec’s calculators produce general estimates to help you train and plan. One-rep max figures come from standard formulas such as Epley and Brzycki, Wilks scores use the published Wilks coefficient, and protein and macro targets use common bodyweight-based splits. Results depend entirely on the numbers you enter — bodyweight, lift loads, reps, sets, target weights, plate and bar weights — and individual results vary. Nothing on the Service is medical, fitness, nutrition, or training advice, a diagnosis, or a coaching program. Always consult a qualified physician before starting a new exercise program (especially with any injury or health condition), a certified coach for lifting technique and loading, and a registered dietitian for nutrition. Lifting heavy carries a risk of injury: warm up, use proper form, and set up safeties and spotters before attempting a near-maximal lift.

Accuracy and Disclaimers
While we aim for correct formulas, we cannot guarantee that every calculation is error-free or suited to your circumstances. Results are estimates based on standard methods and the figures you provide; your actual strength, capacity, and nutritional needs may differ.

Limitation of Liability
In no event shall GymRec or its suppliers be liable for any damages (including, without limitation, injury, lost progress, or harm to your health) arising out of your use of, or inability to use, the Service, even if we have been advised of the possibility of such damages.
Third-Party Links and Ads
