A workout regimen is a structured plan that outlines specific exercises and activities designed to improve physical fitness. These plans can vary widely based on individual goals, such as building strength, increasing endurance, or losing weight. Common components include cardiovascular exercises, strength training, and flexibility workouts, often tailored to fit a person's lifestyle and fitness level. Many people follow workout regimens to stay healthy and achieve personal fitness goals. Popular methods include high-intensity interval training (HIIT), yoga, and weightlifting. Consistency and progression are key elements, as they help individuals track their improvements and stay motivated over time.
