I have been practisng yoga for 5 years, it’s a very good exercise, i love it so much. I just put on sports wear during the yoga lesson,the materiais of the clothing should be comfortable. There are some obvious effect seen after practising yoga, the pain is lessen during the menstrual period, the body figure looks much better than before, or looks very firm. During the yoga, especially in the beginning, whenever the poses make me feel painful, i wiill quit doing it , as wait for the next poses, as i do not want press myself too much. As time goes by, you will be able to do many poses, even the difficult ones. just don’t give yourself too much presssure, it’s just a body exercise, but patience is needed, as it will take time for you to see the result.
