I have a yoga mat I want to use to exercise in my room but it moves around on the tile floor and isn't as firm as I'd like.Any ideas on what I can do?

Get a good hammer drill with appropriate sized mason bits, 4 bolts, sinks and washers. Drill the holes, Hammer in the sinks and with the washers bolt that yoga mat down! 🙃😈😁

Get a thicker mat. They’re more expensive but worth it

two sided velcro??

Duct tape
