Can someone explain this to me...

how come you lose weight and get toned if your heart rate is higher?

i mean like biking for example... how come you can loose overall weight from all parts of your body, but the only part getting exercise are your legs?

because you burn energy to move your legs, adn the body can't choose to only burn fat from the legs.
