I'm in high school.
I want to get better at gymnastics because I'm jealous of a kid in my class. So far I've made solid gymnastics-wise progress for ~5 weeks.
I wanted to run a 1500 in ~5 minutes becuase it was something most of my friends couldn't do. I joined the athletics club and got injured ~
Lots of people want to exercise to get bigger muscles, lose weight, six-pack abs popping, impress their friends, impress girls/boys, etc.
Something in me tells me this is stupid and unsustainable, that this is silly and will end badly. If these reasons weren't mine, I would laugh. It's really unglamorous when it's boiled down. Since I don't know how to phrase this, this voicing of insecurities, into a question, I will end with
thoughts, anyone? What's a good reason to want to exercise?
Ps. Please add good tags.
EDIT: What are some good motives to exercise. Looking big and beating your classmates, I know they are not good reasons.
