Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 12

On day 12, since it was the HIIT legs workout in Lift 4, I switched up the morning workout to do the Legs workout in Shaun 20. That one is all squats and lunges and does use a medium-weight dumbell for a couple of the exercises. The Legs workout in Lift 4 had some brutal exercises (triple bear and catchers jumps). I still mostly have to hold the bear position as I find even stepping hard in that one.
