Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 28

Day 28's workout was again the 645 cardio routine, modified with different exercises. For this workout, I worked in the jump knee switches from P90x's plyo routine and switch kicks from Insanity while still doing soccer runs and speed skaters from Lift 4.  And, on the pulse squats I did the full jumps and not just lifting onto my toes.
