It s a chore, but a valuable one. Aerobics burn calories. Though aerobics are a necessary part of an effective weight loss program, it is generally overrated by instructors and enthusiasts. In the simplest terms, we know the body is an extremely adaptive organism. Fat storage is the secret to the body s survival.
Muscle is metabolically expensive for the body to maintain as it consumes far too many calories.
Thus, our bodies naturally gravitate towards fat, not muscle. Putting everything together, individuals who overemphasize aerobics encourage the loss of lean tissue. In addition, as an adaptive response, your body endeavors to make any repeated activity easier. If you continuously lift heavy objects, your body will get stronger. Continuous running will increase aerobic capacity and encourage your body to lighten the load , promoting muscle and fat loss.
