I started the Couch to 5K on Sunday. I was waiting until I lost 2 stone but I have struggled so much with my weight since Christmas that I thought sod it. I actually managed to complete day one with no stops, which surprised me.
You only have to do it 3 times a week with a rest day between which I think most people could manage. Lets see if by the end of the 9 weeks I can run 5k.
I've also started "Planking" - this is basically where you hold yourself in the same position for a certain time. This is surprising hard hence why it is recommended. You feel the burn surprisingly quickly. It works a lot a of muscles so we shall see if this works too.
