I am a recent convert to yoga. The crazier extremes don't interest me, but it is helping to really balance things out after a year of right side, low back & hip issues. I'd take a couple of classes to get the idea and go from there. My teacher does private sessions where she will work with you to design an at-home routine based on where you are & where you need to be. Obviously the value depends on the teacher...
TV is highly over rated. Haven't owned one in 25 years.
