Simply said, cardio will only burn muscle if you don't give it any other option. Muscle loss may be avoided by balancing your workout and nutrition. A balanced balance of strength and cardio exercise will allow your body to function optimally, allowing the two systems to complement rather than compete. Strength training builds muscle, which increases your metabolism and helps you lose weight. Cardio exercises get your heart rate up, which is great for burning fat but doesn't build muscle. It's important to understand that muscles burn calories, even when they're not being used. So by building muscle with strength training and then exercising to use it or lose it with cardio, you'll keep yourself looking slimmer longer. The best type of exercise for weight loss is one that makes you feel exhausted after you finish. This means a combination of strength training and high-intensity cardio workouts are most effective in reducing waist size. However, both activities can be done separately as well. Strength training increases your metabolic rate, which means more calories are burned day-to-day. Cardio gets your heart rate up, which is great for burning fat but doesn't build muscle. So by adding more cardio to your routine and taking it easy on the joints with less intense activities, you can still have healthy results. You should try to work out every other day instead of every day.
