Workout Update: Insanity Max 30/Chalean Extreme/Body Beast/P90X Hybrid Day Round 2 Day 4

Day 4 was the second time doing the Tabata Power workout this week. I probably modified more than I indented to, especially with the power jumps, which caused me to hurt my back on Tuesday. I did as many unmodified moves as I could, but definitely not as many as I would have liked. But, I made it through without further tweaking my back, so that was a plus.
