Plus Sized Gym Bottoms for Apron Belly?

Hello all! I have a bit of an apron belly - my stomach sags down to the top of my thighs. I’d love a good pair of workout pants that supports the stomach & keeps it away from my legs. (I am trying to use some seated cardio machines, and my stomach is constantly knocking against my legs. It’s very annoying!)

USA. I’m generally a Size 20. Not petite or tall. No specific price point. Thank you!
