This isn't the 1st time that have heard the numbers 60 - 90 minutes of exercise. All my life I had heard 30 min. Now I know 30 min is better than nothing, but I think our goal needs to be 60 min. I have also heard that you need more exercise to maintain if you have been heavy before.
I guess this means I had better adopt an active lifestyle as well as going to the gym to get that 60 - 90 min.
