I am quite a few stones overweight, partly because I haven’t been able to exercise for over 2 years. Now I am trying to do some, including trying to walk every day ( aiming for 10K steps to start with). I wondered about trying the sofa to 5K challenge but I have never been a runner, even when I was super fit practicing karate. My hairdresser told me that a client in her late 60s did it power walking & has lost a fair bit of weight. Has anyone successfully done sofa to 5K? Any tips welcome. I really am totally out of condition & can’t go on like this. Get out of breath so easily, aches & pains etc.
