That's terrific! Getting exercise in is my biggest challenge...
As for the person who said it gets easy and routine... unfortunately, that has not been my experience.

I have been exercising regularly for almost a year and have been doing an avg of 30 min/day (or more) for months now. But on MANY days I still have to fight with myself to go and exercise. I do it, because I know I should, but it is a struggle. Most days, getting my shoes on is the hardest part. Once I'm dressed for it, I do it.
I know lots of people do get in a groove, and find or rediscover a love of exercise, but not all of us do! For your sake, I hope you're not like me! But if you are, know that you can struggle with it, but still do it!
