1-RM 1.1.0

Whether you're an avid competitor in weightlifting or simply aiming to enhance your strength and overall fitness, understanding your one-rep max (1RM) is an indispensable tool. Our user-friendly calculator allows you to easily and safely determine your max and keep track of it over time for any exercise you desire!

In the most basic terms, your 1RM indicates the maximum weight you can successfully lift for a single repetition on any given exercise. It is generally beneficial to know your maximum for key lifts such as the squat, bench press, and deadlift. However, even if you don't plan on training with heavy weights, knowing your 1RM remains crucial.

Many training programs are designed with a certain percentage of your rep max in mind. For instance, you might come across recommendations like using 65% of your 1RM for a specific exercise. In order to follow these guidelines, it is necessary either to test your 1RM or make an estimation. Testing your 1RM can be a highly intensive process that requires great caution to prevent injuries.

Thankfully, you can estimate your 1RM without undergoing actual testing! Exercise scientists have developed a formula that offers reasonably accurate results for most individuals, and this is precisely what our calculator employs. With our tool, you can effortlessly calculate and monitor your 1RM as well as various percentages of it for any lift imaginable.
