The law of diminishing returns, in the sports and fitness context, is not particularly controversial. When you’re a neophyte, small amounts of training produce big gains. When you’re a hardened vet, huge training loads are needed to squeeze out tiny gains. Eventually, and inevitably, you hit a ceiling. We’re so used to this pattern that we seldom stop to ask a very basic question: Why?
A major new review paper from Jeremy Loenneke’s research group at the University of Mississippi, published in Sports Medicine, takes on this question in the context of strength training. What, if anything, prevents us from continuing to get bigger and stronger indefinitely, assuming we’re willing to keep upping the training dose? Despite how obvious the question seems, the answers remain elusive. There are several theories, though, which offer some insight about how to push your own plateau a little higher.
The most obvious explanation for training plateaus is that you let the workouts get too easy. A few years ago, I wrote about a surprisingly effective ultra-minimalist once-a-week strength training routine. People who…
