Wow! You've taken the first steps (clique!) and gotten some results of *just moving* your body! Congratulations!
I think (IMHO) that its harder for women to start exercising and stay with it...we come up with 'grand' excuses! Use your hubby as a motivator, you are hanging with us on the forum (great motivator), check out other things that interest you and see if you wanna investigate further...just do it (as Nike says).

I am a facilitator at my facility for containment exercises when folks lose their control. It makes me sad when there are women & men who cannot get down to the floor (due to weight & lots of inactivity) and they're half my age (40). And this is just for training....I cannot certify them as fully competent for all the containment exercises simply because they have no range of motion (except standing upright or sitting down).
