The most surprising thing was the food - it's quite tasty and satisfying. I was never hungry and did not experience any cravings. The fitness trainers are excellent. Having seen the TV show, I was really nervous about the physical element but there is no one screaming in your face. You are challenged to do your best, but in a positive, encouraging way. I was very pleased with the results I was seeing and decided to stay for an additional week-the timing of this Groupon was perfect!
