Estimate your one-rep max for any lift based on a submaximal set. Free, instant, and accurate for your strength training.
Estimate your one-rep max (1RM) for any lift based on a submaximal set. This helps you plan your training intensities and track strength progress over time.
No calculations yet. Calculate your 1RM and save it to see your history.
This tool is essential for strength athletes, powerlifters, and general gym-goers who need to program their workouts based on precise percentages of their max, or for anyone wanting to track strength progress without constantly performing maximal lifts.
Accurately estimating your 1RM is crucial for effective strength training programming, allowing you to set appropriate weights for working sets, track long-term progress, and minimize the risk of injury associated with frequently testing your true maximum. It's a foundational metric in powerlifting, bodybuilding, and athletic conditioning.
