I love Yoga! I finally started up my practice once again a couple of weeks ago after a half year hiatus and it was amzing how out of shape I felt after my first class. (Long story short I could not afford Yoga classes and never felt motivated enough to do it by myself. I like the class environment because it challenges me. I know excuses, excuses. LOL) Our muscles are like elastic bands so the more we work on them, the more they will stretch and the easier it will be to practice postures etc. It's great that you're starting yoga as I have always found that it helped me not only in my strength and fitness factor but in my daily energy levels, sleep patterns and overall health. It's really a great form of exercise. I just need to be less lazy sometimes and do it more often (giggles and rolls her eyes as she once again finds herself on her lazy a$$ at the computer. LOL) But seriously, it really is great for you. Just don't worry about what you look like in class. I'm sure all of us have felt totally out of shape and extremely awkward at some point (I know I have countless times ) but the great thing about Yoga is that you are focusing on yourself and your own strengths and weaknesses and any good Yoga teacher will help you work thorugh your insecurities. So go forth and stretch! Namaste
