days 5 and 6

Days 5 and 6 were a bit challanging.  The legs and back workout was hard.  I can't even do one pull up! What I like about the legs and back is that the instructor alternates between the two so that you don't get bored and so that your legs are shaking so bad that you can't keep going.  Yesterday was a cardio kickboxing like workout.  It was ok.  I think i need to put more effort into it because I was not really breathing that hard or breaking much of  a sweat.  Today is my day off and the I start week 2 tomorrow.
