This application is a warmup sets and reps calculator for various strength training programs. You choose your working weight for each exercise in the program and the warmup sets and reps are automatically calculated, along with the weights you need to place on the bar. As you use it, it remembers preferences such as bar size, unit system, and the weights for each exercise when you come back for the next workout.


Programs are defined in JSON and placed in the programs folder. An example program:

  "title" : "My Program",
  "exercises" : [{
    "name" : "Squats",
    "max" : 500,
    "workouts" : [{
        "sets" : "2",
        "reps" : "5",
        "multiplier" : 0.5
      }, {
        "sets" : "1",
        "reps" : "5",
        "multiplier" : 1.0

Each exercise is defined with a name, a max weight, and an array of workouts that include sets, reps, and the multiplier for the working weight. For a more complete example, view starting_strength.json in the programs folder.
