I have always walked briskly 30 minutes a day outside when the weather permitted, and on my treadmill when it was crappy outside. Been doing it for years. My weight never really changed, just kind of stayed the same. This summer, at the end of June, I stepped up my game. I started jogging a mile every other day(just a light jog, I am not a distance runner by any means), and rather than 30 minutes, I jumped up to an hour walk per day. Twice a week, I started doing a half dozen 40 yard sprints. I guess it is kind of my own version of interval training. I take off one day a week from the exercise, usually mow the lawn on that day so I am still getting steps in, though I don't really count steps. I also started eating a little better, more veggies, smaller portions, etc... I'm not depriving myself, but have really cut down on things like soda, sweets and fast food. Since June 23rd, I have lost 15 pounds. First 10 was super easy, last 5 not as easy, but I am still pointing in the right direction... I wasn't really overweight at 5'11" and 190 lbs, but I was soft. lol Dropping that 15 lbs, I feel so much better, and look way better, just thinner in my mid section and face most notably. Lots of my clothes I was wearing in the spring fit me a lot looser now. I don't have to replace my wardrobe, but another 5 lbs, and that might be the case. I don't feel that I need to drop anymore weight, but we'll see what happens. That old 30 minute walk a day was good for me, but it just didn't seem to be doing anything, so I made a change, and it worked...
