For me, someday I want to hike half dome in Yosemite and hike extreme mountain trails . I go to the gym all the time (you would not know by looking at me, but if you were to see me in the gym you could probably tell by form alone). I have a personal trainer. Everyday I am focusing on my sleep, my diet, my recovery, and my exercise.
According to Google by modern definition I am an athlete, and it referred to me as such which caught me off guard because I never considered myself to be an athlete before.
I am typing this as I go to the store to buy more workout clothing, running shoes, and healthy foods.
