Execution:
- Set a submaximal weight for your patient that he can lift for more than 1 time (80kg in the example)
- Count the times your patient was able to lift the weight (for example 10 times)
- Look at the percentage on the left that the number of repetitions correlates with (for example 10 times means 80% of the 1RM)
4. Calculate the 1RM: Take the chosen (e.g. 80kg) and multiply it by (100/percentage) in our example 80kg x (100/80) = 100kg
The further you are away from our 1RM in terms of repetitions that your patient performed, the less accurate this calculation becomes.
Knowing your 1RM for a certain exercises in turn gives you different options:
- Tracking progress in terms of strength over time
- Choosing intensities that you want your patient to work with
