One of my motivations for taking yoga is exactly what you mentioned...the only things you really need to practice are yourself and gravity! Since I'm on the road a lot I'm hoping that I'll learn some good yoga routines that I can do in a hotel room.

I'll be 44 in a few weeks...my back is starting to give me some problems - especially on long steep climbs. So I'm hoping that the yoga will help with that a little bit.

Cheers,

traveller
