The short story is ..I am actually quite tall and large.Like better part of 16 stone (there! said it. done) I have always tried the approach of trying to lose weight so that I can exercise (or more specifically run). This approach has not be successful at all-- ever. SO I Google and found this program. Love it. The music: kind of cheesy. Laura: Love her. Me? not so much. I picked a 5k for the first part of October. I am trying to stay committed to the 3 runs a week. My knees are killing me....I am not defeated. But I am worried about not being at the starting line or mid line or finishing line for the 5k I signed up for. Then I will feel defeated. Am I as always aiming to high to soon?
