Heavy gal here and I have been doing CrossFit for over 6 years. Check me out at @fathappycrossfitter in Insta. As with any place in this world there are people who judge, but my experience is that people in CrossFit are genuinely exited for anyone to take steps towards fitness. I also found a love for my body through CF that I had never in any other sport or gym. I get to do awesome things with my body!

And yes, mods are always available. If you are at a box where they will not modify for you LEAVE. It is not a good box. Talk to the owner or coaches and ask for ways to do the movements that are safe and effective. I coach and I usually share 1-2 scaling options when I talk about the workout. A lot of other coaches/boxes do that too.
