If u increased the amount of muscle mass in your body what other changes will occur

ONE THING THAT INCREASES IS YOUR MUSCLE CELLS AND THE ABALITY OF NERVES TO ACTIVATE MUSCLES

You would begin to gain weight and become heavier. You would either become more toned on how your diet is or the mass of your body would begin to get bigger, again based on your diet. Also your circulatory system will be healthier and more blood would pump through your body. Last but not least the obvious answer you will begin to lift heavier objects.
