Man, I did this my first two years of marriage and PACKED on the weight.
I had terrible depression that kept me from leaving my home. I finally got my junk together with the mental help I needed and started working out and got a job. 40 Lbs lost and I stopped. I've maintained my weight since then (probably due to my job), but I'm attempting to get back into the swing of things.
Right now my routine starts in the kitchen with keeping my daily calorie count under control. I'm attempting to get into a schedule of walking my dogs regularly also (to help stengthen them in their old age).
Once I get my eating habits and daily walks with my dogs down, I'll begin adding an actual workout routine to that.
Small steps for big goals! I have about another 15-20Lbs to lose! Diabetes and heart disease runs in both mine and my husband's family. We are refusing to let that happen to us.
