When I was in Highschool I was able to jog 7 miles a day and even in College I was pretty active doing 4-5 miles every other day. Now that I just turned 29 Ive been sick with myself and the way I looked so I said it doesnt have to be this way. I went back to my old ways, Im jogging 5 miles a day and eating clean now. Its much harder to lose the weight now that Im older but I know its still possible, I just have to do that much more. It all depends on how bad you want it when it comes to weight loss.
