1 Rep Max Calculator - All Exercises

Ever wonder how much you COULD be lifting for any given exercise, including: the Bench Press, Squat, Deadlift and many more?

While we all know that how much weight you can lift isn't everything, but it is a BIG factor in your gains and your progress in the gym.
Use our 1 Rep Max Calculator by setting the sliders below to the best set aka the highest weight you can do for any give rep amount.

For example: If your "best set" is 200lbs for 5 reps, then you would set the WEIGHT slider to 200lbs and the REP slider to 5. The number shown below the slider is then your calculated theoretical 1 Rep Max. Now that you know your current max - you can start working towards increasing it!
