A NOTE ABOUT SAFETY One-rep max calculations are estimates, and accuracy can vary based on training experience, technique, fatigue, individual physiology, and other factors. Attempting a true one-rep maximum can involve significant risk. Use appropriate safety equipment, have a qualified spotter when necessary, and never attempt a weight you do not feel prepared to lift safely.
