Well, I actually own a CF gym. I started out in weightlifting for sport as a kid, progressed to competitive bodybuilding and power lifting through my 20’s into my 30’s. I was a competitive MMA fighter and I loved all of it. CF to me was the best of them all. We
Lift heavy weight, learn some basic gymnastics and the intensity is like fighting but nobody hits you. Lol
As for injuries all gyms and coaches are different and yes there are injuries but that true in all sports. Look at the programming and see what it looks like. You obviously know how to train so make sure it makes sense to you. Proper warmup , 1-2 heavy movements, accessory work then conditioning . I’d be happy to answer any more specific questions.
Give it a try and form your own opinion. Don’t listen to people who have never tried it and say it sucks
