I had to be at work at 3:45 AM on both Monday & Wednesday last week but had about an hour break from 6:30-7:30 AM so I actually worked out there both days doing Insanity on Monday & a cardio/strength circuit I made up on Wednesday. I'm glad I worked out because it helps me feel more awake so I don't fall asleep at my desk on those days! Also, my back pretty much feels back to 100% now.
Monday: Insanity Pure Cardio (40 min)
Tuesday: taught 1 hr Spin/TRX
Wednesday: 40 min Cardio/Strength circuit
Thursday: taught 1 hr Spin/TRX
Friday: 1 hr Clocked @ System of Strength
Saturday: 2 mi (9:52 pace) + Insanity Plyometric Cardio Circuit (40 min)
