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. AND ONE MORE THING... My 1 Rep Max will never interrupt your workout to ask you for a rating or review. If you enjoy using the app and would like to support it, you can leave a rating or review anytime from Settings.
