Hello to you both. Yes, yoga is very good for body and soul. For beginners, i would say it's essential to find a class. You need to see how the positions are done and have a trained eye watch that you are doing them properly.
Once you have some basics, you can start doing them on your own at home or to video. But classes are good for the social and motivational aspects too.
I find if I do yoga and meditate daily, my body really tones up and I am much calmer in my daily life. It sort of makes you look inward to what you are putting into your body and mind and things like wanting to eat healthier often come with it.
I've been lazy and not doing it and am feeling fat and sluggish!
