I just finished the 6-week challenge this past Sunday. I was very excited that I surpassed the goal weight of 25lbs (I was -26lbs in 6 weeks). The trainers are amazing and made working out fun (and tough). It takes a lot of self-discipline to not fall back into your old eating habits but totally possible. The workouts were challenging but can be modified for you if needed. I was able to get my money back since I hit my goal and completed tasks required along the way :) much recommended!
