^^^^ This! I can't imagine a life without working out and it keeps my sane. I run 3 miles every other day, no matter what is going on in my life (always first thing in the morning--best way to avoid procrastination). I weight train 2-3 times a week but am not as consistent as I am with running, plus I don't put in half of the effort. I'm trying to improve on this because weight training is just as important as running. I used to run 30 miles a week (5 days @ 6 miles each) plus weights but am in better shape doing just 3 miles every other day and the weights. It's not necessary to make it such an effort, just 30 minutes is perfect. I think that's the best way to become consistent--30 minutes is easy to scrounge up but an hour makes it seem insurmountable some days (and easy to skip).So, early AM and keep it it short and work hard during that time! Also, I have found it's easier to be consistent if you can workout at home rather than having to go to a gym.
I also walk a huge local bridge 3x a week at night while my kids are at practice, much better than just sitting around waiting. I got a little out of control last year and started running the bridge (in addition to my EOD AM runs) and blew my foot out. Now I am just back to a leisurely stroll at night--again, doesn't help to overdo things.
A great book is Body for Life, by Bill Phillips. He emphasizes 6 days a week of 20 minute exercise, alternating 3 days of 20 minute runs with 3 days of weight sessions and a day off. Excellent program that is easy to follow! My husband lost 25 pounds in a short time following that. The 'diet' shouldn't even be called a diet, but a way to eat properly. A protein carb and a vegetable--5-6 meals. Digging my book out!
