Good job on the workout Emma!!!
Sunnykells.......I can't say I know anything about the dvd's, but I would add them in after your weight training circuits. Unless, its her helping you with the weights or is it just cardio? The book really is key though to jumpstart your metabolism. Good luck.
Just for us......the lat pulldown is different from day 1 and day 2 (wk1). I made the same mistake also. Day 1 has your hands in a position of the end of the bar, while day 2 has your hands in the position of in the middle of the bar working your triceps. This way it works 2 muscle groups. Hope that helps.
As for jumping jacks, I sub in a very fast minute of skipping rope.
