The so-called yoga mat is generally a foam mat with a width of 35 cm and a length of 1.5m (there are also sizes), which is not very thick and lasts for 1cm.

The main thing is not to be dirty when doing various yoga postures!

You can do yoga on the bed, sofa (if Simmons is too soft, otherwise the movements will be out of shape) and carpet. If your floor is clean, you can also practice directly on the floor!

The crawling mat you said should be ok, simple things!

I wish you a good figure!
