Re: joining a box
my story is far different from yours. Joined as an older woman aged 58.. started with a personal trainer who then moved to another state and recommended CrossFit... after watching CF on youtube it took a while to make the firt appointment.. I peeked around the roller door into the box saw all these sweaty fit "young" people working out doing stuff that i would never dream of.. tried to run away but fortunately had been spotted and so was obliged to at least talk with these people.. and so there my journey started and it continues.
celebrated my 60th with my first ever strict pullups!
