If you think that avoiding drinking during the workweek but spending per night from the party at weekend drinking so much is no matter, your idea isn't true. You can consume over 1,000 calories from drinking (wine, beer, soda, etc) and eating (chicken wings, pizzas, peanuts, etc). It means you may get extra unexpected pounds. Yoga still plays crucial role during my life. Unfortunately, lot depends on the teacher. My present teacher will be the least experienced as being a teacher and I find difficult she will not correct us to enhance our poses and our posture. This is a restorative class where I go now to gradually get back after my back problem. Her sequencing along with the structure with the class is very inconsistent. However, in the past I was extremely fortunate to do business with very experienced yogis both as practitioners and teachers.
