How to calculate your one rep max Your exercise programmes may contain references to your 1 rep max, this is the maximum amount of weight a specific muscle group can lift for 1 repetition.
Calculating your one rep max is important because it allows you to work with the correct weight to enable you to achieve your long term goals.
Attempting to assess your maximum one rep max by trying to lift your maximum weight on a fitness machine is not recommended.
The best method by which to select your one rep max is to select a weight you know you can lift more than 5 times and gradually lift it. Repeat until you feel you can lift no more. You can then use this assessment to select a heaver weight and gradually work towards discovering your one rep max.

Rate of self perceived exertion (SPE), SPE's are easier to calculate than heart rate training zones, so they're often easier to use on a day to day basis.
