Werking for the weekend

He also did calenstetics for 30 minutes.  Then I went home, made my 2nd shift snack+food pack and the second client wanted to go hiking.  so we hiked a mile and a half.  I burned about 600 calories before I was able to even get 967 into my belly.  I may need to start doing bigger breakfasts and more snacks (lean protein types)   My legs hurt e that I aglad or ompression ks.
