DAREBEE Workout: What it Works
Mr Grumpy is a workout designed to make you feel good on the days when you just feel low and grumpy. It activates your muscles, works your cardiovascular system, gets your aerobic system going and, because it won't drain your batteries, it will only leave you feeling much improved both physically and mentally, afterwards. 
Extra Credit: 1 minute rest between sets.
