HERE IS THE CATCH: You can't cheat. You take pictures in the beginning and the end of the challenge, of yourself in "airport attire" and they also give you a keyword to place by the scale while you stand on it. Snap those pictures and submit it to be reviewed by official referees. I did the 4% challenge a while back ago when ShayCarl (Youtuber; Shayloss) did one and I lost because my Aunt Flow decided to visit me during my last weigh in; Needless to say I was so excited for her visit.
This time, I'm doing the 6-Month, 10% challenge. Same rules apply but you are to lose 10% in 6-Months with a $25 monthly bet. So, if I don't win this one, I'm a schmuck and lose a lot of money; And if money isn't motivation enough to keep up with physical exercise and my running goals, I don't know what is… *cough, cough* Ryan Gosling…
