WEIGHT LOSS TIP: Aerobics are usually the exercise of choice for any one wanting to lose weight however you will burn a lot more fat and lose weight a lot faster if you will perform some weight training before engaging in aerobics. The scientific reason for this is what is known as the glycogen sparing effect which refers to the body's preferred energy source of glycogen derived from stored carbohydrates.
Whenever you exercise your body will prefer to use glycogen as fuel however as your stored glycogen is depleted your body will start to use other sources for energy like fat in order to delay running out of glycogen. The key to burning more fat during your workouts is to perform exercises that use up your glycogen stores quickly so that your body is forced to start burning more fat. Unfortunately aerobics alone do not have a high enough intensity to quickly burn off your glycogen stores so you never really burn much fat unless you are doing aerobics all day long. This is why most aerobics instructors are lean while the average person in their aerobics class is not. Weight training, on the other hand, is a much more intense workout that will use up your glycogen stores rapidly. The way to get the greatest fat burning effect out of aerobics is to do thirty to sixty minutes of weight training and then perform your aerobic exercise. This way your body will have no choice but to burn fat as a source for energy which is exactly what you want when you are trying to lose weight. And remember if you need a little extra help with energy and fat burning then take a good thermogenic like Thermo Phen Phen about thirty minutes prior to your workout to increase the fat burning effect even more.
