Knowing your 1RM will help you know how much weight you can lift for a given number of repetitions, it can also be used to check changes between measurements to know if the training is being effective or not.

To calculate your 1RM you need to know how much weight you can lift and how many reps you can do in a particular exercise, it is advisable to perform the calculation with less than 12 repetitions, because from there the calculations become less reliable.

User Reviews

There are not many exercises to chose from. For example I do dumbbell bicep concentration curls and on the list of workouts there is not a single one that includes using dumbbells. Developer please see this and change it!
