How to learn to rock climb
It made me 
"Totally worth the experiences because it challenged me both mentally and physically."
How I did it: The rock wall @ my gym. I joined a group of other people that met once a week and they helped me learn the basics and then every time I would go to the gym I would hit the wall first before doing other things.

Lessons & tips: If you get really into it, get your own pair of rock climbing shoes because it totally makes a difference than using regular sneakers.
