If you like group workouts, I think it’s good. I’ve done CrossFit for about 5 years...it’s the only way I’ve been able to consistently get to a gym. To me, it’s a similar feel to the football workouts I did in high school so I enjoy it quite a bit more than solo work.
There’s a wide variance between gyms and it’s really up to the coaches as to how safe it will be. You get a bunch of moms and meatheads doing Olympic lifts at high intensity, and you’re asking for trouble without proper coaching.
That said, the two gyms I’ve gone to, the coaches were great at teaching and enforcing form, monitoring load to back down the meatheads asking for an injury, and varying programming to ensure you’re not overtaxing one muscle group. They typically focus on intensity over hitting prescribed weight/movement, so encourage scaling often. If you can’t do a movement or lift well, you’ll have a worse workout and you increase your chance of injury.
Biggest complaint is pairing heavy deadlifts with box jumps (or heavy dl in a time based workout period). That’s dumb and seems to be designed to fuck up your shins. My injuries have been limited to shin and hand tears.
