It helps to know how achy the body gets without it. In my case, the back pain I had from desk work is entirely gone now. If you focus on the form rather than reps and getting through it, paired with some good music, you can reach a focus state. There are off days of course, but I'm surprised that I enjoy it much more than I used to, where my motivation dropped off quickly due to being externally motivated (visible gains). Now it's kind of cool to just see your ability change over time, better balance, capability to do more advanced exercises, etc.
