Katherine Roberts seems like a nice, well-intentioned lady, genuinely interested in helping golfers. Her PAR, BIRDIE, and EAGLE level Yoga for Golfers tapes and DVDs are minimalist at best. There really is very little there. I would highly recommend Yoga for Inflexible People or Vinyasa Flow Yoga. These programs are filled with VASTLY more help,information, and instruction at less cost. Or, if you are really serious about helping yourself, look up a local Yoga instructor and have them guide you for a few dollars more.
