An exercise regimen is a structured plan that outlines specific physical activities to improve fitness and health. These regimens can vary widely, including activities like cardio, strength training, and flexibility exercises. They are often tailored to individual goals, such as weight loss, muscle gain, or overall wellness, and can be adjusted based on a person's fitness level and preferences. Typically, an effective exercise regimen includes a mix of different types of workouts, scheduled throughout the week. For example, a balanced plan might incorporate aerobic exercises on certain days, followed by resistance training on others. Consistency and progression are key components to achieving desired results and maintaining motivation.
