I have a very physical job and these pants are not only comfortable but actually energizing. The stretch is amazing, I wear an XS and my sister who wears M tried them on. Not only was she able to put them on but after she took them off I was still able to wear them without needing to "was the stretch" out of them. They went right back to normal size. I have a pair for every day of the week and a couple pairs of the Sculptor leggings as well just to be able to change it up.
