I've been keeping track of my daily exercise using a checklist on the wall.
I wanted a nice small printable one. I looked around, and there were several for sale for $2. I made a free one, instead.
Here's the download link: 26 row. Or if you hate blank rows, here are some with less rows: 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
And of course, I customized one with my own workout routine.
