I haven't really thought about daily challenges but do think it is a good idea. It will change it up. For food challenges (30 days at a time) I was thinking things like: tracking everything honestly daily (even if you binge or over eat), not going over your daily sodium (or others such as sugar, carbs...) intake, cutting out certain things such as soda or fast food for 30 days, The exercise routines where going to be some of the 30 day challenges such as 30 day shred, 30 day squats, 30 days of not missing a workout things like that. A lot of it depends though on the previous month's winner. The winner will be choosing both a food and exercise challenges for the new month.
