A few years ago I changed my approach to working out during that time of the month. Instead of pushing myself through workouts or doing the vice versa and giving myself “5 days off” only to never began my fitness plan again, I found a way to look at the start of my cycle as it’s own fitness journey.
That in itself has worked out brilliantly!
I use a planner which I’ll put below. On the first sheet I put the days that my cycle runs (sidenote here: the planner geek in me is way too happy that I fit an entire year on one page!)
