Hey Bernie,
I may have taken something too literal when I understood it was best to do Yin cold, rather than warmed up.
Before my Ashtanga practice I have learned to do a 15 minute warm up to help prevent injury, especially to the lower back because of all the up-dogs. So when I heard it was most effective to do Yin before body, muscles, and all, warmup, I jumped right in cold. Well after 10 days of everyday non-warmed up Yin, I can't get out of bed due to lower back issues. Having had these problems in the past, I know how how to recover from it, I also know how to prevent the problem from occurring, however if warm-ups in Yin are not suggested??? you get my drift... I think I know the answer to my delima, but since I'm so new to this particular yoga style, I feel I need an authoritative opinion.
Please advise...
As always, thank you for everything you do,
Cheers,
Daniel
