Absolutely! In fact, you are the perfect candidate for yoga. Give it a try and over time you will notice that yoga helps you to become more flexible and stronger. Everybody is different, so never feel the need to practice poses exactly like the teacher: he is only there as a guide (and has been practicing yoga for over 15 years). Listen to your body, don’t force yourself and stay within your limits. Also, like any other exercise program, please consult your doctor before beginning to practice yoga.
