All content on The Rep Max Calculator — including the one-rep-max calculator, Wilks and DOTS score tools, warm-up and plate calculators, strength standards, and every guide article — is provided for general informational and educational purposes only. It is intended to help you understand common strength-training concepts and to make rough estimates. It is not a substitute for individualized professional guidance.
This site does not provide medical, health, nutritional, physical-therapy, or personalized training advice, and no content here should be interpreted as such. We are not your physician, coach, or trainer, and using this site does not create any professional or client relationship. Reading or using anything on this site is not a replacement for consultation with a licensed medical professional or a certified strength coach.
Before beginning, changing, or intensifying any exercise or training program — especially resistance training or maximal-effort lifting — you should consult a physician or other qualified healthcare provider, particularly if you have any pre-existing condition, injury, or health concern. You should also work with a qualified, certified coach (such as one holding a CSCS or equivalent credential) who can assess your technique, leverages, and readiness in person.
One-rep-max figures produced by this site are calculated estimates derived from published formulas applied to submaximal sets. They are projections, not measured results, and they can differ meaningfully from what you could actually lift on a given day. Your true performance depends on factors these formulas cannot see — sleep, fatigue, technique, nutrition, injury history, and daily readiness.
Actually attempting a true one-rep max, or training at loads near your estimated maximum, carries an inherent and significant risk of injury. You should never treat an estimated number as a target you must hit. If you choose to test or train at high intensity, do so only with appropriate warm-up, a qualified spotter, and proper safety equipment under professional supervision.
Exercise and strength training involve inherent risks, including but not limited to muscle strains, joint injury, and other serious harm.
