It might seem really terrifying to you as a women, but you need to build some lean muscle. Muscle is so important because it’s the engine of your body and with more muscle, the higher your metabolism is and the more calories your body burns naturally.
Keep in mind that there is no relationship between muscular strength and muscular size. Size is independent of your strength so you never have to worry about getting big because you can use work on strength. Size is almost completely dependent on how many calories you eat. The more calories, the bigger you are going to get.
The best fat burning exercises are those that not only get your cardio up and working but your lean muscle too. This is why I love weight training routines that use your body weight as resistance along with dumbbells.
As you continue to do workouts like these, you will naturally lose fat and weight. However, don’t expect your weight to go down in huge quantities. It really depends on how much fat you have to lose. But since lean muscle weighs more than fat, the scale can deceive you.
