WarmupReps

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

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. The Next.js app loads these files through src/lib/programs.js.

Development

Install dependencies with npm install, then run npm run dev for local development. Production builds use the standard Next.js server output via npm run build.

Deploying to Vercel

This app is now configured as a standard Next.js application for Vercel, not a static export. To publish it on Vercel:

1. Import the GitHub repository into Vercel.
2. Keep the default framework preset as Next.js.
3. Use the default build command npm run build.
4. No custom output directory is needed.

Vercel Analytics is enabled in the root layout using @vercel/analytics/next.

• Fork the project.
• Make your feature addition or bug fix.
• Commit.
• Send me a pull request.

New programs are welcome in pull requests. Add the JSON file to the programs folder, then register its filename in src/lib/programs.js. The app will generate the corresponding program and exercise routes from that data.
