I never watched Biggest Loser, but saw an interview with Jillian, and she was tough, but she also seemed to be sensitive and care about people, so that won me over and I started getting her videos. Many of them were above my skill or tolerance level, but I drudged on. This video is great because it gives me a sense of accomplishment. I am now 42 & pregnant and this gives me a great workout without putting my highrisk pregnancy in any danger. Overall I reccommend this for the people who are new or not lovers of exercise.
