From all I've heard about the benefits of Yoga I'd like to give it a try to increase my flexibility and improve my posture/core strength. I understand it can help a lot in these areas as well as with my breathing which I know I need to improve, I've also heard there are several different forms of Yoga. Which one would be most suitable and how is best to go about starting it? What equipment will I require?
Edit: I also meant to ask, are there any potential negative effects of Yoga? Can it be damaging to joints or could you cause yourself awkward strains?
