On hour cardio plus pullups

30 minutes on the stair climber (level 12) and 30 minutes on the elliptical. I went pretty hard on the elliptical. Heart rate was consistently above 160 and maxed around 170. Threw in two sets of 15 pullups. Moved up to level 13 on the pullup machine (level 14 yesterday). Just more 13 levels until I am doing 15 pullups of my own body weight :) That could take some time...
