I do a weekly yoga class during my lunch break. It’s great.
I seem to be the exception on this thread, as I never fart (there’s the odd occasion when I have to stop one popping out, but it’s not like as soon as I get in the class I start uncontrollably farting.
I also don’t generally end up sort the next day – I might be a little stiff in certain areas if we’ve been concentrating on a particular area, like hips….
You’ll probably end up ‘glowing’ rather than sweating.
Water bottle & a towel is a good idea – I mainly use my towel as padding under my knees, or for putting under my head when lying down.
Don’t feel like you have to ‘touch your toes’ or any other nonsense. If you get into a stretch, but have actually barely moved, then it is still an effective stretch for you….
If you keep going, it’s actually quite interesting as it teaches you a lot about your own flexibility and how different everyone’s bodies are.
