How To Use

One Rep Max

Each calculator extends AbstractOneRepMaxCalculator which requires the weight and reps as a constructor argument.

We have included a variety of 1RM calculators so you can use your favorite methods.

$oneRepMax = new BrzyckiOneRepMaxCalculator(100, 2)->calculate();

You can also determine the exertion amounts for a particular one rep max given that you provide an AbstractOneRepMaxCalculator

The following code:

$values = ExertionPercentages::calculate(
    new BrzyckiOneRepMaxCalculator(100, 2)
);

Will output

[
  {
    "percentage": 10,
    "value": 10.285714285714285
  },
  {
    "percentage": 20,
    "value": 20.57142857142857
  },
  {
    "percentage": 30,
    "value": 30.857142857142854
  },
  ....
  {
    "percentage": 90,
    "value": 92.57142857142857
  },
  {
    "percentage": 100,
    "value": 102.85714285714285
  }
]
