Starting yoga - should I be worried?

As you are going to start yoga, I would suggest you to read this out blog.bootybands.com/2018/07/13/5-things-you-must-know-before-starting-yoga/

As a Christian I would not practice yoga since the intention of yoga is a path to attain salvation through union with a false deity.

I have had 2 yoga teachers who are Christians.

Its a great thing to do.

I can’t do yoga because I can’t do the head down positions- I suffer from postural vertigo. I do Tai Chi instead. I credit my classes with improving my balance and posture.

I do pilates and Tai Chi. I find Tai Chi excellent. I have poor balance so I rest my hand lightly on a chair back for some of the exercises. All the exercises are done standing up so there is no need to get down to floor level or cross your knees.

Perhaps you could do it for six weeks or so to give it a fair trial. If you're still not keen, give it up.

No, you don't have to worry about anything. Just start with a normal pace to check if it suits you. If it does then well and good otherwise you can opt for some other exercise. Nowadays there are different exercises for each and every thing.

Nothing to worry about. Just do what you can during your classes. Most likely, this will rather improve your mental strength as well and give you peace of mind for your doubts.

I couldn't even manage the seated yoga! - there was a lot of moving the head about and I got mega-dizzy.
