Any suggestions for a great (preferably thick) fitness mat that doesn't slide?

Hey Lizzie, if you head to "How To Get Started" I have a shopping list for all my favorite equipment. I have the mat listed in there, it doesn't slip and is relatively thick. You can always double-up your mats, I do that a lot when I take group X classes with bad mats 🤪
