So now my "butt wings" hurt.
What are butt wings? They are the fleshy pads over the back of your hips below where "love handles" like to hang. In other words the base of the muffin below your "muffin top".

I have a new Gym Partner. Best one I could find (heehee) but seriously is in it for the sweat, pain, loss of function, and humiliation that I am.
Yesterday we tried a new machine I never braved before. No idea what it's called but it requires a very large amount of coordination for which I lack. You stand on two round steps and push back with an angle away from your body. Kind of like Roller-blading or the push off when starting down hill on skis.
The resistance, I found, adjusts itself depending on what your heart rate is if you're working on the "fat burn" workout. So I started out with a level 2, pretty hard. But that forced the heart rate to jump up to target level, as well as send my thighs on fire. When the resistance dropped down (up) to 7 my feet felt as though they had hit the floor and was near in splits as the foot pads extended outward and down. So I found myself doing steps out to the backward-side of my torso with enough area open between my ankles to fit 2 of my shoulder widths.
YEAH OUCH!
Didn't notice until after the muscles in my body started to deplete of the extra circulation from exercise that my butt wings were very tender. I have to attempt walking up and down my stairs with as straight and closed legs as I can in order to not collapse in the stair well and cry. So now it's even funnier to my husband to watch me move from one floor to the next.
New goal: obliterate the Butt Wings!!
