Personally, one of the best ways for me to quickly ruin my day is to overthink my workout plans. The second guessing of the most “optimal” way to approach a task can be paralyzing. I always have a “plan” but that plan has to be adjusted based on any number of factors on a given day including how I’m feeling, the weather, what I need to work on, and what’s happening over the next few days. When I hit moments of “?????” and can’t decide, I have to always remember the basics: show up, do at least 20 minutes of the planned workout before deciding whether something needs to change, and no matter how the workout goes, find something that I learned, that went well, or that I saw that made me smile.
