I know this is an old thread but could not read it without entering my input 🙂
I’m a CPT & Crossfit L1 trainer. I’m very lucky to coach at a gym where the priority is safety (attained by adhering to good form). We’ve had our share of mild injuries but what gym doesn’t! Each member completes a very through orientation course ( 4 wks 3x wk) before they can jump into the reg classes. they also have an assigned mentor coach who helps them with the transition. Our members range from 20 – 65 yoa and the movements are scaled to their ability. Everyone works at the same intensity but the variables are individual ( not a cookie cutter program).
As far as Rhabdo, this can happen in any environment with any level athlete if the conditions are there. Crossfit has actually a lowever incident rate than other modalities because coaches are educated on it and gauge their clients. I know alot of PT’s that don’t even know what it is.
I don’t want to write an editorial on the pros and cons of CF so I’ll end with this; there are risks in all fitness modalities however the key is teaching clients to maintain focus on safety and form while they challenge their bodies.
