Hi Shhambo!

Congratulations on your wonderful progress!
There's actually a scientific rationale for the new government recommendations. Studies show the vast majority of successful losers exercised for a hour a day, every day, while they were losing and that's why the government is recommending an hour per day for weight loss. It sounds like you're right on track with that exercise recommendation - good for you!

But, as you note in your post, even more exercise - 60 to 90 minutes a day - is recommended for weight loss
maintenance. The reason for the increase in the recommended time is because other studies, such as from the National Weight Loss Registry, show that's what successful maintainers have to do to keep the weight off.
And somehow most of us maintainers do manage to fit in those 60 - 90 minutes of exercise a day. It's something we've talked about a few times here in Maintainers - you might want to check out these threads about exercise:
My personal exercise schedule is 45-60 minutes of cardio - bike, crosstrainer, or elliptical - about six days a week. Plus I lift weights 4 - 5 days a week for about an hour at a time. So I average anywhere from 510 to 660 minutes of intentional exercise a week, which is between 73 and 94 minutes a day. Plus I have a fairly physical job in a gym but don't count that

. Those numbers aren't unusual for many of the maintainers - maybe some of the others will stop in and talk about what they do every week.
I think it's not a big deal for most of us to do that much exercise because it's become a very natural and normal part of our lives. We all had to exercise a lot in order to lose the weight and it truly became a lifestyle for us. In addition, most of us have discovered that exercise makes us feel upbeat and energized.

Exercise is so much a part of my day, every day, that it would be like skipping my shower not to go to the gym. It would just plain feel WRONG!
If I ever start feeling like my motivation for exercise is flagging, all I have to do is think about going back to being that miserable, unhappy, exhausted 257-pound woman who was convinced that she hated to exercise. Those painful memories always get my butt out of bed and off to the gym at 6:00 AM!
Don't be surprised if the 60 - 90 minutes of exercise just happens naturally for you. You might not even need to think about it once you reach goal - it just may have already become a permanent part of your life.
