I explained it incorrectly. We are up and out of the saddle for about 2 or 3 minutes at a time. But after a few of these intervals, along with some sprints mixed in, I start to feel the pain.
I think I may be attempting to 'hover' too much and I'm trying to keep my head and shoulders too low, thus putting an unnatural and uncomfortable arc in my lower back. I'm going to keep working on it.
Just out of curiosity, why are the 'popcorn jumps' not good?
