Well, I often tense up my neck muscles, especially under the chin. Any exercise is simply tensing and relaxing. Why wouldn’t it work for the chin?
After my two pregnancies I started doing 80 – 100 sit ups a day. I had the flattest tummy ever, well into my late 40., I didn’t necessarily work out the rest of my body in any particular exercise, either.
I quit doing them about 8 years ago and I’m getting disgusted! So in the last week I’ve started doing lazy, funky tummy crunches while watching TV. I’ll lean forward on the couch, kind of pick my feet up off the floor, then tense my stomach muscles down tight, and hold them for a count of 20. I’ll do that 4 or 5 times an evening, just whenever. It’s easier to do than forcing yourself to sigh sit down on the floor, then count sigh…SO boring. I’d devise different ways to count just to take my mind off of the tedium.
Anyway, since I started that lazy tummy crunch a week ago, there is a difference already, a difference in my overall strength.
Go for it. Take some pics now, and again in a month.
