You need a yoga mat if you are going to do yoga a regular mat or towel won’t work- you need something non-slip. If you are heavy you especially need extra hell keeping you hands and feet in place.

Yoga Mats are typically about $20-30.00

XS Cargo Stores have yoga mats on sale for 9.99
Giant Tiger Stores also have for 9.99- not sure if this is sale or rgulaer item

Loblaws/Fortinos/Zehrs have nice yoga kits- mat + 2 blocks + strap + yoga dvd + eye mask ( not sure what for! ) for 19.99. This is a great deal. I biought for blocks and have extra mat for kids to do with me…
