When you attend aerobics classes do you believe that you are getting slimmer and burning calories? Aerobics makes you feel out of breath and its hard work so you must be losing weight. According to the science world, they say that’s just not true, aerobics could be making you fatter.
Aerobics is a cardiovascular exercise that works out large muscles such as the legs. In order to flow more oxygenated blood to the muscles the heart needs to work harder. In turn the lungs have to provide the oxygen meaning they have to take in more air which is why it seems harder for you to breath.
Aerobics might sound great until this point but actually the calories you burn are very little compared to other physical activity. Image doing one hour of aerobics and burning fewer calories than are contained in a skinny latte and chicken sandwich. During an average hour of a good aerobics session you burn approximately 540 calories. You would need to burn 590 calories to burn off the latte and chicken sandwich.
A family and sports doctor, Dr Nick Krasner, states, “Once you start an exercise program you could begin consuming more calories than you’re burning simply because your body expects more food or calories.”
Also aerobics could in fact break down lean muscle tissue because the body is fighting to create energy. Losing muscle means you could be damaging your internal organs that are made of muscle and you’re slowing your metabolism. Your metabolism is the body’s natural way of burning calories using muscle. If your metabolism slows you’ll be burning fewer calories during the day.
Losing lean muscle tissue also could throw you into yo-yo dieting. You’ll lose the weight you want to but if you veer away from the diet and exercise you’ll gain the weight back. Some people gain back more weight than they started with making them bigger and feeling worse about the possibility of losing weight. Again, the decrease in muscle slows the metabolism in turn burning fewer calories making it harder to lose those unwanted pounds.
Aerobics exercise might also cause hormonal changes. According to Dr, Jeya Prakesh, an anti aging expert, an increase of growth hormones and the cortisol hormone can be seen when exercising.
Cortisol, a stress hormone, is intended to get our bodies ready for flight or fight which requires a good supply of energy. There’s also been evidence that excess cortisol is linked to fat storage. The stress hormone supplies the energy by increasing your blood sugar by generating new sugar called glucose from fat and protein in your liver. As your blood sugar increases your body starts to release a hormone called insulin which also leads to fat storage.
Birmingham University have done studies that show excess fat around the tummy area can actually create cortisol. This can lead to continued obesity or even worse type 2 diabetes.
If aerobics can make you gain more weight then what you started with, let’s see what you can do to lose weight without losing muscle and keep the weight off for good.
A good way to lose weight and stay thin is weight training. This doesn’t mean you’re going to start looking like Arnold Schwarzenegger but you’ll be able see real results. The key is resistance exercises that build lean muscle tissue and at the same increases your base metabolic rate (BMR).
Resistance exercises can be done by working out on weight machines or actually lifting weights. While you are doing this type of exercise you start to rev up your metabolism making it easier to burn calories all day. In essence, lifting weights will stabilize your weight and make it easier to sustain your shape by booting your metabolism even if you decide on a slice of chocolate cake.
Weight lifting gives you the exact combination of building muscle and burning fat. The best part is that a mere twenty minutes of resistance exercise is equal to entire hour of aerobics. By listing weights you will be performing a high intensity workout focusing on one group of muscles at a time in addition to strengthening and protecting your internal organs.
