Kat,
to answer you in my opinion, YES, working out is very very crucial. I don't think I would be where I am at without all the hard gym workouts I have done and am still doing. (In fact I am leaving for an appointment with my trainer right after I post.)
Shelby, I have read that before that the band will do about 40% of the work, but in all the times I have seen my doc, he said that the band might, and that is a big MIGHT, have done 25% of the work, but the rest was all me. From the moment I was given the OK to get back in the gym, well, I did.
Lindsay, LOL... you made me laugh too, especially when I so understand where you are coming from. You are really a wealth of information and I really hope one day I have great ripped arms like yours.
I am striving for it.
Hugs,
Kristi
