After three years of gradual weight gain due to health problems, now sorted, I am determined to lose the 5 stone I am advised would give me my ideal weight. Today is day 1 week 1 of the 12 week plan. I have a big trip booked for 9 weeks time, what would you guys suggest is a reasonable target to have achieved by then? After so long without much exercise, except short dog walks, I feel daunted by the couch to 5k plan. Again suggestions would be much appreciated. Unhelpful 'friends' ask why, at nearly 64 I am bothering. I like to think I can make up for lost time and be as fit as I can possibly be, for as long as possible.
