More of Sara Armanius. She actually quit CrossFit a few years ago because the workouts were too tough on her body, as we can see clearly in many photos over the years
Most of this is probably not pain. It's fatigue. In CF you burn a tonne of calories each workout and it all always depends on wether you can still breathe and if you have the strength to snatch those 80 kg for the millionth time.
If you're in pain, it means that you're injured. And if you're injured you shouldn't be working out.
It's not all pain you see, it has more to do with perseverance to go as far as they think they have to.
I love seeing them in pain during/after their workouts. The dedication to making their bodies as ripped as they are required a lot of sweat and tears. I’ll start the thread with Sara Armanius and Alison Scudds. Bonus points to posters who post a girl screaming in pain.
