But for the woman who wants to get a sleeker physique, weight training can help develop long lean muscles. Why
do you want to do this? Well muscles are fat burning machines. The stronger your muscle is, the more fat it will burn.
How it works: When you work a tiny little bicep muscle that hasn't been used in a
while, the muscle breaks down. This is what you want to happen, because during your rest period when you have stopped all
weight bearing activity, your body will use calories already stored in your body to build this muscle back up. This
new muscle will be stronger than it was before. When you next do more weight lifting exercise, you will break it down again,
causing it to again build up into an even stronger muscle. By doing this you are training the muscle to get stronger. As it
takes calories to build up muscle, your body will be using up calories from your fat deposits. The end result is that lean
muscle forms and the fat deposit becomes thinner.
From this explanation, one might think you can do weight training and completely skip the aerobics part of exercise.
While weight training is beneficial to those who need to exercise less or whose weight loss efforts are hindered by chronic
ailments such as epilepsy, weight training only helps you gain stronger muscles. It does not necessarily help you climb those
stairs better or walk long distances. For this you need to exercise your heart, which can only be exercised through aerobic
activity. When the two types of activities are used together, you can be rest assured you are getting the benefits of both
worlds.
