I have been using an app called Couch To 5k to jog. It coaches you for several weeks. The gist is that it can help you get off the couch and be able jog a 5k marathon. I have only ever completed the entire training once, and then never jogged again.
You can see in this screenshot how many times I attempted to do the entire training and the gap from when I actually completed to when I tried again and again. How terrible!
Welp, if you look at it, you can see that I started again. I completed one week today.
Got to keep going!
