Common myths about fitness and health include beliefs such as lifting weights makes you bulky or that cardio is the only way to lose weight. Another myth is that you need to work out for long hours to see results. In reality, strength training can boost metabolism and help with weight loss, while short, high-intensity workouts can be effective for fat burning. Additionally, fitness is not solely about aesthetics but is fundamentally linked to overall well-being and health. Understanding these myths helps individuals set realistic goals and adopt effective strategies.
