Lack of energy
I consume quite a bit of protein daily and get as much sleep as I possibly can but some days, like today, I have very little energy and doing 20+ burpees completely wipes me out. On a good day, I can still only do the burpees and a very short workout. If it were up to me, I would do killer workouts everyday but unfortunately, my body just won't let me. It's times like this that I feel like I will never meet my goals.
