Confession time. My wife just started Crossfit and I gave it a shot. I went to a introductory session and one private lesson to learn some of the lingo and exercises. I like it...and my wife looks pretty good in those leggings.
I think I'll give it a go.
Good luck. No shame in giving it an honest try. So long as you get a good coach, focus on form and avoid injuries, it should be nothing but positive.
It's not my thing but I'm going to be objective.
