ad astra per aspera
Yes. I'm no trainer but from what I've seen you would be much better served by splitting up your training sessions (focus on one thing at a time) than by half-arsing everything and getting yourself hurt.
In all of the universe there is only one person with your exact charateristics. Just like there is only one person with everybody else's characteristics. Effectively, your uniqueness makes you pretty average.
Not everyone who does CrossFit half-arses everything.
Our coach is very focussed on form, and we spend a lot of time working on things before a WOD. And he also walks around during it to make sure we are doing it right.
Originally crossfit was designed by elite athletes to challenge themselves. Then it became a fad and succumbed to marketing, bullshit etc and has slowly devolved into fuckarounditis (a chronic disease, suggested cure is swift termination of infected host). Most crossfit gyms are mass marketed, hyped up bullshit...same as most gyms, personal trainers, exercise classes, martial arts classes, mma classes etc, but there are still some good ones. You just have to find them.
