@expressforsuccess I've been doing CrossFit for 5 years. In that time I've had 2 surgeries- 1 on my hand from a cross country ski accident (of all the sports to get hurt doing...) and 1 on my foot for a bunion that had become very painful. After the first surgery, when I was new to crossfit and just starting to be able to Rx a few things, I stayed out of the gym way longer than I needed to (3-4 months). Why? Because I'd worked hard to get to Rx and didn't want to go if that wasn't going to be possible. After the foot surgery, I was back in the gym as soon as I could drive (5-6 weeks) and for the first few weeks I. Modified. Everything. Within 3-4 months, I was back to most movements, but it took almost a year to run again. I learned during that time that 1) no one, including me, cared if I went Rx on a workout, 2) going to the gym and doing something, anything, was huge for both my mental and physical health, and 3) my coaches are really creative with awful ways to change things up and happy to help work around physical limitations to make sure I still got the best workout possible.
Now? I have 0 hangups about needing to Rx- If I can and still get the right stimulus, cool. If not, that's fine too. And my coaches purposely coach in way to encourage that kind of behavior. When explainging the workout they often give some criteria of what you need to be able to do if you want to Rx. For example, we might be doing something with strict pullups and they'll tell us that if your max is less than 5 strict, you should us a band (or another modification). I also really like that unless we're doing a named workout, the "prescribed" weight is a % of your 1 RM.
