I have been doing yoga once a week for the past two years. This has helped my balance, core strength and keeps my back happy. I too enjoy watching the younger ladies clad in spandex. I have had the fact that I have tight hips pointed out at least each session with some of the poses I try to get into. My instructor says that we practice yoga and it is a 50 year journey. As long as I work towards the pose and feel the strain that is good. I recommend it for anyone over the age of 30. I just wish I would have started it much earlier.
