To elaborate; I literally cannot focus on a workout, particularly a cardio routine, for longer than 5 minutes or so. If the best possible wourkout for me were to do 20 minutes of rowing, running, or cycling, I will literally want to kill myself after five minutes. Typically it won't come to that, so I'll just half ass it, call it quits and take the walk of shame home, bothered, unmoisturized, unhappy, out of my lane, unfocused, languishing. This is not due to over-exertion or the overall difficulty of the exercise but I guess some kind of latent inability to focus on any task for longer than the bare minimum.
I guess the simple answer is "Just mix it up, doofus", but when I do that I end up just half-assing even more. What is to be done?
Unfortunately part of exercise is being able to tolerate monotony and repeat the basics day after day.
Cycling or running to places around the area I live in that I haven't been to often/at all, and exploring them, is probably the most fun cardio exercise. When you run out of places to explore, you cycle or run further out. Unfortunately this can get unsafe sometimes, so don't do it if you feel unsafe
