Thoughts on crossfit?

Hi, Having a mini debate with my friend on whether crossfit is trash or not. I said it is; she said it's not. I've never done it because some people on here say it's bad; she's done it before and says it's great. I said most bodybuilders don't do crossfit because it's trash and she said it's because crossfit is too hard for them. So...thoughts on crossfit? Please help. Thanks! I didn't find the right solution from the Internet. References:https://forum.bodybuilding.com/showthread.php?t=172905561 Product Design Video
