Hip Movements?

Hi everyone! I started beginner salsa a few weeks ago, and I’ve noticed that a lot of the people in my class have really nice hip movement. Mine feels pretty stiff in comparison. I’m not sure if I’m just too tense, if I’m overthinking it, or if it’s something that comes with more practice. Does hip movement develop naturally over time, or is there something I should be working on to improve it? Any tips would be appreciated!
