Hi Debbie,
I've been practicing Yoga for many years, and came up with three DVD's that are extremely beneficial.
YOGA SHAKTI with Shiva Rea; This features a Yoga Matrix. You can choose any pose you would like hard or not so hard and put it in a routine just made for you. This is an Awesome DVD, and my favorite.
MASTERING THE SECRETS OF YOGA FLOW by Doug Swenson; This DVD covers ( in a flowing sequence), intermediate, and advance Yoga. Doug is an outstanding teacher, you can not go wrong with this DVD.
AEROBIC YOGA by Ganga White and Tracey Rich; This DVD is absolutely for a person who loves flowing YOGA, who already knows the basic poses, but want more. This is an intermediate to advance DVD. NOTE: There are several Yoga DVD's out there with Gango White and Tracey Rich, but this particular one is outstanding. Make sure your DVD says "AEROBIC YOGA".
Good luck,
Janie
