I had once before lost 80 lbs but gained back about 75% of that just because I was stubborn with not exercising AT ALL and eating whatever I wanted without being careful and now I am back on track, using the C25K again which worked for me before!!! It is truly a wonderful program even though I don't particularly love exercising and running but it DOES work! I add in some strength training and wa-la! I am getting married in June and HOPE and PRAY to lose at least 20 maybe 30 lbs by then! I've been at it since January non stop and am at week 7 right now! I go to the gym 2 sometimes 3 nights a week and spend an hour there. Typically while my daughter is at her sport practice. My fiancé goes with me and uses the same app!! He loves it too! He's a great motivator and he too is needing to lose weight.
My biggest downfall is sugary foods but if I really want to eat that stuff I know I must exercise. I am 37 so I cannot just automatically be thin!
