I was quite a good sprinter at school, I was on the school team four years running. I was also fairly good at high jump, as well as gymnastics and I played volleyball.
You show it. In phys ed in high school (private school the public schools cannot do that with the enabled) we were worked really hard lifting weights and running. The coach told us that it would help us a great deal later in life, it has. I continued exercising since and weigh the same now as I did then, 40 years later.
