It sounds like you're enjoying crossfit, that's great, our cult is getting bigger, lol. I've been working on going really deep on squats lately too. I can do it up to 125 lbs but have a harder time at 135 lbs. and up.
My weight is staying the same just like you, but I've definitely noticed improvement in the shape of my body so I'm sure I'm gaining muscle. So I guess we both need to stop worrying about the scale for now and focus on getting stronger and faster.
