So, I gave up on shred. After day 2 of level 3, had a bit of pain in right abs & corresponding area of back. didn't think much of it. did day 3. still there. Then carried heavy bags thru airports, carried heavy kids on my right hip while in FL, pushed heavy cart thru Costco, came home & 13 days later did day 4 of level 3. I think I tore/strained something.
Pain is now basically gone, but not totally normal still on the right side of back & abs. Back muscles in that area ridiculously tight, especially when I first wake up, & when they are tight, the ab area aches as well.
I really think I overdid on the Jillian & the other stuff, as I can tell certain movements/activity make it worse, or at least more noticable. I'm hoping to start over with level 1 soon & see if it is ok, or not. Just a mild trial. It is just too darned ab intensive!! But I did love the results I was seeing! The ab/back stuff, was, however exactly as DD described her torn ab muscle from ab intensive Yoga. UGH!!
