Workouts from November to March

I’ve done a pretty good job of tracking all of my workouts on a simple piece of poster board in my bathroom, near the the scale. Some weeks were better than others, but overall, out of 140 days (i.e. squares), I missed 62 days, which means I worked out on about 65% of the days from November 9th to March 28th.

I’ve tried to track my workouts in apps, but they are too complicated. It’s not that I do not understand how to use them, it’s that they want to do too much. I just want a simple thumbs-up/thumbs-down of did I workout or not? I will typically add a few lines of meta-data on what I did that day, and possibly my weight, but those are not that important. I just want to know if I did or did not that day.
