They even organised free personal training for me during this time (enter the 'Enforcer!'). During the 12 week challenge I lost 13.7kg, 4.2% body fat and 37cm! December 30th 2005 my interviews, progress and before and after photo's were published in the WHO special issue "Half their size".As so many readers wrote and said they wish they were able to do something similar I decided to run an 'online 12wk challenge' for them where I would record their progress on my site each week. Unfortunately I was unable to keep the complete stats from this challenge due to some technical issues.What I do have listed below is my own stats for the 12wk period and the total that the group as a whole lost.
