I have been practicing yoga for a year - approximately three times per week. I was looking for videos to use for the days I can't make it to my yoga class.Like many others who have commented on this video, I worked out in a gym, took aerobics, step class, etc. for many years. I checked into yoga after suffering a knee injury.If you're looking for a fitness type workout and have never tried yoga, you will probably enjoy this video. If you know anything about yoga and practice with a good yoga instructor, you will hate this video. Not enough time is spent on proper form, and I found the instuctor to be annoying. Don't push yourself to do the advanced postures unless you have stretched beforehand. Not enough information on form is provided to make this a safe workout for beginners.
