There are many kinds of yoga.

Slimming and stovepipe yoga, /programs/view/0tfgmfi _ m3s/
You can watch it online or download it for study.
To wear sportswear, there are special yoga clothes on the market, which are very nice and enjoyable with relaxing music.
However, for those who have just come into contact with yoga, don't force it, that is, don't push it too hard, but stretch it slowly step by step, otherwise it won't be enjoyment and fitness if it hurts.
I hope it works for you.
