Day 4, Jillian Michaels' 30 day shred level 1

Today my knee was not as sore as yesterday so I was hopeful with the workout.  It hurt a little but not nearly as bad as it did last night, so yea!  I was able to complete the workout but I felt a little sluggish.  The good news is that my muscles were not as sore today as they had been every other day.  I think it's like Jillian says, my body is adapting.
