Just when you thought your stomach was done for, we came up with a way to fight those calories you've gained from a home-cooked meal. Plate-ups! They're sit-ups with a set of plates as a substitute for weights. Simply take five plates, small or large (just not plastic), find a spot on the floor and do 5 reps of 20 sit-ups. Repeat until your stomach feels just as thin as it did when you first woke up (you know what I'm talking about!).
