I have never felt compeled to write a review before but these dvd'd are FANTASTIC. i have been using them only for two weeks and used them about 4-5 times a week and can already see results!! although two of the dvd's in the set are the same just with different titles i find using the 30 min active dvd for cardio burning and the abs and glutes dvd for toning is a really good workout. but don't expect the toning to be a gentle session like on other fitness dvd's because it's almost the same speed as the cardio!! it's absolutley exhausting!! but you feel great for having done it and once you've got your breath back you feel energised and as previously said i can see results already after only 2 weeks.
