Going to a yoga class is always more helpful to me than trying to do yoga on my own. I took a few yoga classes and thought I would be able to continue doing yoga every morning at home, but I forgot some of the poses. It's easier to follow a teacher through all the poses. Everyone can participate in the class, so don't feel intimidated if you have never done it.
Whatever it may, going to yoga class or meditation, all will be good for health and mind. But please make a use of yoga accessories as it is very supportive to you for doing yoga and also used for the meditation. There are lot of shops and please see the best like yogasuppliesonline.com.
