Not medical or professional advice
The calculators on AthleticCalcs (including but not limited to the one-rep max, bench press, squat, deadlift, Wilks, powerlifting total, dunk, and vertical jump calculators) provide estimates only, based on established mathematical formulas and general population data. They are not medical advice, personal training advice, or a substitute for guidance from a qualified coach, physical therapist, or physician.
Accuracy of estimates
Rep-max formulas, Wilks scoring, and jump-height estimates are all built on general models that do not account for individual factors such as technique, limb length, training history, fatigue, or injury. Your actual performance may differ meaningfully from any estimate produced by this site.
Assumption of risk
Strength training and athletic activity carry inherent risk of injury. Do not attempt a heavy lift, jump test, or any physical activity based solely on a calculator result. Always use proper form, appropriate warm-ups, and a spotter or supervision when attempting maximal or near-maximal efforts.
No liability
AthleticCalcs and its operators assume no responsibility for injury, loss, or damage resulting from the use of any calculator, estimate, or content on this site.
Consult a professional
If you have a medical condition, injury history, or are new to strength training, consult a qualified coach or medical professional before beginning any new training program.
