Hi belle I do a khai bo class that is meant to burn 600 calories!!! A days food, I still took it easy though and afterwards I actually thought I was going to die! I felt so light headed and sick, but it leads to a tough call dosent it! Don't eat and don't go or eat and go! Don't know the right answer to that one! Had to go on a food break check my thingy for why! Week 4 belle your doing amazing! You can do it!!!!!!!!
