I compiled a few points below – if you’re interested in reading more, I have included full article links below the points. Have a great rest of your week!

• Exercise naturally stimulates your metabolism. All types of cardio can significantly raise your metabolic rate, at least in the short term. Cardio increases heart rate, which stimulates your metabolism to produce more energy. Even after your heart rate returns to normal, your metabolism remains stimulated because your body has an increased need for energy. 
• Metabolism is boosted by increasing the body’s muscle mass and heart rate. Regular exercise increases your heart rate, strengthening your heart. Muscle is the biggest contributor to our metabolic rate. Building muscle mass through our strength training in class is a huge contributor to boosting our metabolism.  
• The body naturally burns more calories each day to maintain a pound of muscle than it does to maintain a pound of fat. Therefore, the more muscle you build, the more calories your body will naturally burn each day at rest. So, just by building muscle, you’ll  increase your metabolism and more effectively burn fat.
• Building muscle mass through strength training is required to speed up your metabolism. Your glutes and thighs are two of the biggest muscles in your body, which make lower body exercises involving these muscles some of the most impactful for boosting muscle mass and shedding fat. 
• Strength training is a type of anaerobic training – breaking down and building back up muscle tissue, which means your body burns calories for 24-48 hours after each session. 
• Cardio plays a part in metabolism, too. Respiratory function is a component of metabolism that you need to work on increasing. Cardio generally burns more calories than strength training. Combining both methods in True40 classes gives clients that balanced, well-rounded workout. 
• Mixing cardio and weights maximizes your workout’s efficiency. It ramps up your after-burn following class due to increased oxygen uptake, and the more oxygen you consume the more calories you burn, resulting in a quicker metabolism.  Doing cardio in the middle has the most impact on your metabolism – meaning that doing combo in the middle of class significantly boosts your metabolism after class.
