is released, just gets out of my body. my very first time getting to the top of the wall and looking down, i was scared to actually come down. i just do not like heights at all. i learned to overcome that fear because it's like you can't be scared of things in life. >> i have students that are 5 years old and i have students that are 65 years old. it was a full body workout, so not only are you working on core strength, leg strength. >> i'm starting to tone up more. the muscles, the shoulders, my legs. >> the movements of rock climbing force the body to adapt on a very frequent basis. the more varied these positions, the more the body has to adapt. what this does is create neural pathways that can enhance our movement, enhance our cognitive function. >> the critical thinking you do in nursing, saving someone's life is critical thinking when you're climbing up the wall to get to the top. i've converted other people to rock climbing and i'm so happy about it.
