The energizing part is yoga moves done fast, aerobically. She talks fast and does yoga fast with very little (if any) attention to the movements into and out of the postures. She is not a certified yoga instructor, she is a trainer, (aerobics instructor). The energizing workout was much more of an aerobic workout than a yoga routine. It made me sweaty and left me with a sore neck and lower back strain. She says during the workout to keep going "for me". Really?? For you? I'm supposed to do this for you? The relaxation is not as driving, but it is the least relaxing routine I have ever done. It would make a fairly good morning yoga, wake up class. The lesson that I learned here is to look up the instructor when buying a yoga video and make sure the instructor is certified and knows how to teach yoga.
