MAT OR NO MAT

office auntie jio J to join yoga class
and J jio-ed us.......
i did not want to join actually, coz hor, last time, well, yoga too slow for me
cannot take it
too much stretching and dun know what am i doing
ended up sprained my back lor
anyway, still not sure whether the back pain is due to tt or not

anyway, since nothing to do after work
might as well do something healthy rite?
hahaha
so i spend $138 and enrolled myself in a 12 lessons yoga class

gg to buy a yoga mat tomolo.........
=))
should i invest in a good one? or just get one tt can used, afterall, after this class, doubt i will continue bah
