"No matter how slow you go, you are still lapping everybody on the couch" true! So next time I'm having a day where I am tired and moving a bit slower than most workouts- I'll remind myself I'm still lapping people on the couch!
This is the painful truth! Sneaking snacks late at night? Even if no one sees you and you don& track what you eat, your body keeps an accurate journal regardless of what you write down in your food journal.
I'm by no means a runner - I have avoided it like the plague in most cases. But occasionally I feel like running just because I can. There will come a day when this body just can't do the things it used to. Live life while you are able to.
