My 1 Rep Max is a straightforward and user-friendly iPhone app designed to help you calculate your 1 rep maximum weight and track your progress over time. It offers a range of popular 1 rep max formulas to estimate your maximum weight for different lift types.

Using the app is simple. Just select the type of lift, enter the weight and the number of repetitions (up to 10), and tap the Calculate button. The app will then display your 1 rep max, allowing you to track your strength gains and monitor your progress.

For users who want more customization options, the premium version of My 1 Rep Max enables you to create your own custom lifts and perform calculations using more than 10 repetitions.

It's important to note that one rep maximum calculators provide estimates and may not be entirely accurate for everyone. Factors such as experience with weight training and muscular composition can affect the results. If you're new to weightlifting, it's recommended to have a spotter present when attempting to lift your estimated maximum weight.

My 1 Rep Max respects your time and will never prompt you for a rating or review. However, if you enjoy the app and would like to show your support, you have the option to rate or review it from the Settings screen.
