Where is the soreness?

Day 29
Luke did his Chest, Shoulders, Triceps day as planned this morning - on the other hand, I slept until 8 am and did the workout this afternoon at 2:30 pm.  It was a great time to do the workout.  There were two girls in the studio and one guy on a cardio machine.  Tony and I practically had the place to ourselves!

I was really looking forward to getting back to resistance training and feeling sore again.  I was definitely struggling to keep up with this one.  This workout was the hardest for me so far in the program - my arms were shaking almost the entire time.  Also, my core was shaking when I would try to do all the different kinds of push ups (slow, fast, wide, one arm-what?!).

I was hoping to be sore by the time I went to bed, but no luck.  I hope I wake up with that aching feeling, is that weird?
