Estimates, not guarantees
The calculators and charts on this site use published formulas to estimate what you might be able to lift. An estimate is not a promise. Your real strength on a given day depends on your technique, your training history, your sleep, your health and many other things a formula can't see. Your true max may be higher or lower than the number shown.
Not medical advice
The content on this site is general fitness information. It is not medical advice, diagnosis or treatment, and it is not a substitute for a doctor, a physical therapist or another qualified health professional. Talk to a doctor before you start or change a training program, especially if you have an injury, a heart condition, high blood pressure, are pregnant or have any other health concern.
Lifting carries risk
Strength training, and heavy or maximal lifting in particular, can cause serious injury. If you choose to lift, you do so at your own risk. Use a spotter or safety equipment, warm up, use sound technique and stop if you feel pain, dizziness or anything unusual.
No coaching relationship
Using this site does not make RepMaxLab your coach or trainer. We can't see how you move, and nothing here is tailored to you. For personal guidance, work with a qualified coach in person.
Accuracy
We work to keep the formulas and the writing on this site correct, and we fix errors when we find them. Even so, we can't guarantee that everything is complete, current or free of mistakes. If you spot a problem, email contact@repmaxlab.com.
Ads and outside links
The site may show ads and link to other websites. A link or an ad is not an endorsement, and we aren't responsible for products, services or content on other sites.
Your responsibility
By using this site, you accept that you are responsible for your own training decisions. See the terms of use for the full terms.
