Last night, I managed to pull something in my shoulder so that means I cannot do a full shred until it is better! I did some cardio and abs. I did a full 20 minutes still but it was more abs and more cardio to replace the strength. It was still invigorating, but not a shred. Hopefully after a warm shower and some Icy Hot I will be good as new tomorrow for day 7 of the Shred.
