Since you like sports, try skipping rope. You sweat a lot and lose weight well. Many of them say that skipping rope for 20 minutes equals running for 30 minutes. I lose weight by skipping rope. I used to weigh about the same as you, but now I've lost dozens of J. I take a rest after school every day and then jump rope. I wonder how much you can dance every day. It varies from person to person.
