Getting Stronger Means Breaking Down First
Muscles, minds and people grow by taking a hit they can recover from.
Sometime soon you’ll help a friend move. A couch down three flights of stairs, boxes all afternoon, dinner on the floor at the end. You’ll feel fine that night. Then, two days on, you’ll get up and your legs will hate you. Going down the stairs will take both hands on the rail.
That ache feels like a sign that something went wrong. Mostly, it’s a sign that something is about to go right.
Two rules are at work here. Rule one says you’re a whirlpool, and trouble is just more water. Rule three says what you feed grows. Your body takes both of them very literally.
First, the hit and the come-back. A day of hard work is a hit. Your muscles get pushed past what they’re used to, and your body takes that as news. It answers by building back a little stronger than before, so the next hit costs less. But here is the part most people miss. The building doesn’t happen while you work. It happens in the days of rest after. The work is the order. The rest is when the order gets filled.
You can see the proof the second time around. Do the same hard thing again a week on and you’ll be far less sore. Your muscles didn’t forget the first time. They got ready for the second.
Second, what you feed grows, and what you stop feeding fades. Load is food for muscle and for bone. Take the load away and they start to shrink. The best case I know is in space. Up there, nothing presses down on the body. On long trips, the spine and hips lose about 1 to 1.5 percent of their bone each month. That’s why the crews work out about two hours a day up there. Their bones aren’t broken. They just stopped being fed.
Third, the size of the hit matters. Too small, and nothing changes. Too big, and you get hurt and lose weeks. The sweet spot is a hit you can come back from. And being sore isn’t the goal. You can grow without much ache at all. Being wrecked after a hard day tells you that you did something new, not that you did something good.
This works on your mind, too. In one study, young people learned a short text in one of two ways. Some read it over and over. Others put it away and quizzed their own memory. Those who read it again felt more sure of it. Right after, they did better, too. But a week on, the ones who had quizzed their memory could recall much more. Pulling a thing out of your head is the hard part, and the hard part is what makes it stick.
And I think it works on people. The hard year that didn’t break you left you with something you didn’t have before. Not every hit is good for you. Some are just too big, and there’s no shame in that. But a lot of the ones you’ll fear most turn out to be the size you can come back from.
Try this for a week.
Pick a move you don’t usually do and that you could do again without getting hurt. Twenty slow squats is a good one. Do them today. Two days from now, give your legs a score for how sore they are, from one to ten, and write it down. On day five, do the exact same twenty squats. On day seven, score your legs again. Put the two numbers side by side. The gap between them is your body learning, and you watched it happen.
One line to remember
Take a hit you can come back from. Rest. Then come back.
