Some people think they can turn fat into muscle.
That is a myth just like turning straw into gold.
They are entirely different substances.
As you become more toned, your body burns off the fat that was covering the muscle and turns it into the energy it needed to create muscle growth.
The fat simply gets used up and disappears.
You will lose fat as you build muscle as long as your diet doesn't include a lot of calories from high fat foods and carbohydrates; its part of the natural process.
The best way to ensure you lose lots of fat while you build muscle is to do both cardio and strength exercises using either weights or body weight resistance.
The strain you apply to the muscles during weight training forces the muscles to grow.
Cardio workouts burn calories at an increased rate than most types of exercise.
The best cardio exercise method is HIIT (High Intensity Interval Training).
You perform the exercises at a normal rate, increase the rate, then return to the normal rate at regular intervals throughout the exercise period.
This cycle burns fat at an increased rate.
As with any exercise program, you need to watch your diet and ensure you eat well balanced meals that don't contain a lot of excess fat, carbohydrates and "empty calories" from sweets.
You must also ensure you get adequate amounts of sleep.
Following these simple guidelines will help you tone up as you lose the extra fat none of us wants to carry with us.
