An education in exertion

How hard you push in the gym needs no drama and no guesswork.

Most of the time, the client already knew the odds were very high that the job could be done. Be it a bump up in load or rep count on the squat, deadlift, pull up, dip or any other move, they knew what was on the bar and knew they could lift it. Pragmatic programming and exercise selection ensure that is the case.

And more specifically, if you could hold a plank for more than 40 seconds, you probably should be moving on to a harder variant: anti-extension planking, body saws, weighted planks, renegade rows. Simply put, instead of having someone yell at you to extend your plank time, you do a plank hard enough to challenge you for 30 seconds and you stop when you cannot execute well.

And that’s where a real education is necessary.

Repetition and time targets are very often arbitrary values. Do 50 reps of this, 10 reps of that, 5 minutes of the other. Meaningless on their own.

What matters more is how many repetitions you had left in the tank at the end of the set you just finished.

If you have 5 or more left, you are probably not working hard enough. There are contexts where that is exactly right: rehab, speed work, technique volume, the opening week of a block. But those should be deliberate choices, not accidents.

If you have 2 or 3 left, that’s a good day.

If it’s 1 in the tank, that’s genuinely hard. Not an effort most people can sustain or even recognise.

If you could only do 1 repetition, either it was a measured attempt you had spent weeks or months building toward, or you were being egoistic.

Now the harder question: how reliable is your estimate?

Not very, at first. Beginners are poor at judging what they have left, and the further you are from failure the worse the guess gets. A 5-rep estimate is close to a fabrication. A 1-rep estimate is reasonably accurate, because the body gives you clear signals when it is near the end: bar speed drops, form frays, the rep takes longer than it should.

So you calibrate. Occasionally, on a safe movement, you predict your remaining reps and then take the set to genuine failure to check the prediction against reality. Do this often enough and the estimate stops being a guess and starts being a reading. That skill is what separates a lifter who has trained for years from one who has simply shown up for years.

Some F-bombs do get dropped after a hard set. There’s grunting, and the occasional yell at the end of a really hard one. But getting yelled at, or yelling at people, isn’t part of any sustainable or desirable training plan.
