A friend of mine used to tell me “health is cumulative.” What he meant was that you could think of your health like a bank account of sorts. Doing certain things added to your overall state of health. Other things subtracted from it. And if you work yourself into a hole, you’ve got to work yourself out of it again.
The same concept applies in the strength world. There are some things that you need to do to stay injury-free. You can neglect them for a while, but the longer you do, the more risk you take. Often, this comes in the form of neglected muscle groups, but can also include other aspects of overall fitness (flexibility / mobility, energy systems, etc).
Recently I was having a conversation about this with another coach. We were both remarking that high-specificity training (even extremely high specificity) undeniably gets good results in the short-to-mid term. But left unchecked for longer periods of time, lifters get injured. We know that a major key to long term progress is avoiding injury. So this very-high-specificity training cannot be a long term solution to your progress.
