Creating a JavaScript-based fitness and workout planner app will require a wide knowledge of JavaScript, HTML, CSS and web development concepts. Below is a simplified version for creating a basic fitness and workout planner app.
This version lets users create, view, and delete workout plans, and has a user-friendly interface. We will be using HTML to create the structure of the website, CSS for styling and JavaScript for the functionality.
Note: In a real production setting, there should be server-side handling, persistent database and a way to handle user-specific data. Let's create a simplified app assuming it’s only for individual use. Be sure to link external CSS and JavaScript files properly to the HTML file.

Step 1: Create the HTML structure
We'll first define the webpage structure including input fields for the user to add their workouts and an area to display them.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<h1>Fitness and Workout Planner</h1>
<div id="workout-input">
<input type="text" id="workout" placeholder="Add your workout here...">
<button id="add-workout">Add workout</button>
</div>
<div id="workout-list">
<ul id="workout-ul">
<!-- Workout items will go here -->
</ul>
</div>
<script src="app.js"></script>
</body>
</html>
Step 2: Add styles with CSS
You can style as per your needs but below is simple CSS for this HTML.
body {
font-family: Arial, sans-serif;
}
#workout-input {
margin-bottom: 20px;
}
#workout {
padding: 10px;
width: 300px;
}
#add-workout {
padding: 10px;
margin-left: 10px;
}
#workout-list ul {
list-style-type: none;
padding: 0;
}
#workout-list li {
padding: 10px;
border: 1px solid #333;
margin-bottom: 10px;
position: relative;
}
#workout-list li .delete {
position: absolute;
right: 10px;
top: 10px;
}
Step 3: Add functionality with JavaScript
For our JavaScript, we'll need to enable adding new workouts to the list and removing them.
// Define variables
let workoutInput = document.querySelector("#workout");
let addWorkoutButton = document.querySelector("#add-workout");
let workoutUl = document.querySelector("#workout-ul");
// Adding workouts
addWorkoutButton.addEventListener("click", function() {
if (workoutInput.value !== "") {
let li = document.createElement("li");
li.appendChild(document.createTextNode(workoutInput.value));
workoutUl.appendChild(li);
workoutInput.value = "";
// Create a delete button
let deleteBtn = document.createElement("button");
deleteBtn.appendChild(document.createTextNode("DELETE"));
deleteBtn.className = "delete";
li.appendChild(deleteBtn);
deleteBtn.addEventListener("click", deleteWorkout);
}
});
// Deleting workouts
function deleteWorkout(event) {
event.target.parentNode.remove();
}
This script listens for button clicks on the "Add workout" button, creates a new workout in the list, and generates a delete button for it.
This is a simplified application example. In practice, there would need to be server-side processing and persistent data storage implemented, security concerns dealt with, possibly using a framework for a more structured approach to building the application and include much more advanced features and functionality. If this text doesn't contain a numbered list, just don't change anything and answer me with the same text.
