Yoga asana (postures) gives us a structure to allow connection with our individual requirements on a day to day basis by finding focus through breath. No matter which class style you choose to practice, from the moment that you start practicing yoga, you immediately feel better. Your yoga practice should be enjoyed, take it easy, practice your asana so that you feel good. Yoga and life is not about depravation or about forcing yourself to expectations beyond your abilities to maintain and achieve. Find that place in practice and life where you are free and enjoy who you are.
