One way to divide humans is between minimalists and maximalists, especially when it comes to fitness. Some of us want to know how to scrape by with the least possible exercise; I’ve written plenty about how to do this, so I’m not going to go over it right now.
On the other end, some of us want to work out All The Time. I get it. I like working out, too. But too much is not a good thing. When we over-train, our bodies start to break down. We get repetitive stress injuries. We get other kinds of injuries just from being flat-out tired. And we stop making progress.
Bodies get stronger and leaner and faster by cycling through challenge and rest. We work our muscles, which makes them sore, and then they rebuild themselves stronger while we rest. No rest means no rebuilding.
Our culture firmly believes that more is better and most is best. Fight the power and get stronger by resting from time to time. Really.
