After my employer canceled our power flow yoga class (because of budget cuts), I've been at loose ends, wishing for a comparable workout. I've tried our local yoga studio, and none of their classes gave me the same kind of fast-paced, heat-generating session that I enjoyed previously. The good news is that I found it in this video! I'm very pleased with the purchase, and would recommend this video to anyone who wants to build strength and flexibility.To anyone wishing for a laid-back, meditation-type yoga, this is not the one for you.
