Hi Fran, I also turned 40 this year. I started with pilates reformer in January to help strenghten my lower back and then moved onto walking. I started seeing positive changes and so I decided to step up to SLOW jogging. I have just completed D1W1 of C25K. I tipped the scales at 17st back in January and I'm now down approx 2st. It's a difficult journey, but one I'm hoping to complete by eventually reaching my goal weight. I struggle with food and motivation and I'm hoping this forum will help me stay on track. Best of luck to everyone!
