I am so excited, I just had to let you all know. After doing Imax 2 for about six times now, I could not figure out how to do Interval 6. I always sort of ended up doing lunges off the top of the step, but I finally figured out.
That one had me stumped for a while too. Until I finally got the idea of tapping first and then switching feet and tapping with the other foot. (at least that is how I think of it)
