This is truly an art form of exercise that is much more than a fad. In whatever manner current yoga students, teachers etc. happened to stumble upon the wonderful philosophy of yoga - the philosophy of combining the sciences of a type of exercise which connects the physical as well as the mental components of the individual - their collective praise of it is virtually always consistent. This is a type of exercise that can truly improve your life overall! If you are trying to decide what sort of exercise will be best for you, consider yoga - and you may never turn back.
