I am not nearly as fit as I want to be. And if I am to increase my capacity in all things, I therefore need more energy to be able to do more. So, I am now committing to doing more, regular and intense exercise.
I know however that I do need to be realistic. The changes I am making I want to last. So the goal for the next month at least is to go on a run every Tuesday evening(lasting at least 20 minutes, and as intense as I can manage), and a fitness class or swimming every Thursday evening.
Ideally I would like to increase the running to run 5k once a week, but I will give that a go after seeing how the next few weeks go.
