I think I'm going to tell my dad that I've been exercising when I really haven't.
Why are you going to lie about exercising?
I don't want my father to scold me.
It's not okay to lie to your parents, your father only wants you to be healthy. You can find some motivation to exercise. Exercising will keep you healthy.
It's only a slight lie and everyone does it. My dad won't know.
It's true that it's just a small lie, but instead of lying you could ask your dad for advice on how to get into the habit of exercising. Exercising is a great way to stay healthy, and it can be helpful to have someone support you as you get into the habit.
