I thought about getting an electric bike. My commute to work involves a 15% grade hill, which is super fun when you're not even properly awake.
Then I decided what I really needed to do was HTFU. So I've been HTFU-ing and limping - I mean, powering up that hill.
Now my knees hurt. Well, not hurt exactly, just...I'm aware of them, in a way I'm not aware of my elbows, for instance.
So I'm thinking, once more, about an electric bike. I can HTFU on the weekends and evenings, when I'm fully warmed up and awake.
