I honestly won't hurt you to take a day off. I know we beat ourselves up if we miss a day of working out, but it will give,your body time to restore and repair from the previous work out. Plus, the mix up in routine will keep your body guessing, which will further pent a plateau of weight loss.
With this day off, keep with your usual eating routines and caloric intake. Tomorrow, get back on that horse and work out.
