Hello!
You are not the only one who modifies the hi/lo section of MIC. In fact, I do the first two sections of the hi/lo with the tape, returning to low impact when things get too uncomfortable and then COMPLETELY fast-forwarding over the third section. Believe me, by the time you do the first two section of MIC and the stepping section, you certainly aren't going to miss that ten or fifteen minute section in between.
I finally told myself I am not proving anything to myself or anyone else by forcing my way through that third section of hi/lo, and I certainly won't prove anything by getting myself hurt with all the endless jumping around!
Good Luck!
Susan G.
