Strength training...

Muscles are active tissue which require constant calories to produce energy, even when at rest. Fat, on the other hand, does not. In fact, in the entire body, muscles are the main users of energy, as muscles need energy to maintain themselves every hour. The conclusion to this is simple, the more muscle a person has (lean body mass), the greater their basal metabolic rate will be.
The moment that you tell any woman that the best way of losing body fat is to increase their percentage of muscles they all say the same thing with a look of total horror on their faces, "Ohh, no chance, I don't want to end up looking like those women bodybuilders who all look like men!". This is the biggest misconception that women have with regard to weight training. One of the most important hormones for muscle growth and strength development is testosterone. Although there are women who have higher levels, most women only have one tenth of the androgens ( male sex hormones ) that men have. On top of this, women also have much higher quantities of oestrogen ( female sex hormone ) than men, which interferes with muscle growth by increasing body fat. The conclusion to this is very simple. Unless you take copious amounts of testosterone, you will never, ever, end up looking like these half man, half woman bodybuilders and that's a fact.
