Most discussions on training frequency focus on muscle only.

But muscle isn't the only tissue that adapts to loading.

Connective tissue has to adapt also.

Every time you load a movement, the tendons and joint structures must absorb the load and re-establish stiffness.

That first exposure may carry a higher cost than the exposures that come later in the session once tissues are warm and movement becomes more efficient.

This creates a trade-off.

Higher frequency loading may reduce the amount of stress per session.

But it also creates more fresh or higher cost loading exposures.

At the other extreme, leaving too long between loading exposures may not be ideal either.

While connective tissue doesn't detrain overnight, long gaps between exposures can reduce the continuity of the adaptation process.

The next loading bout may then represent a much larger acute stress than if the tissue had been exposed more regularly.

In other words:

Too much frequency may create too many fresh exposures.

Too little frequency may create loading spikes that the tissue isn't prepared for.

The sweet spot is often somewhere in the middle.

Most people think rep ranges are only about:

• strength
• hypertrophy
• endurance

But the truth is you can build muscle effectively across a very wide range of rep ranges.

What many people overlook is that different rep ranges also create very different TYPES of fatigue.

Heavy lower-rep work tends to create:

- higher neural demand
- more connective tissue stress
- and greater psychological arousal

Higher-rep work tends to create:

- more local muscular fatigue
- more metabolic stress
- and more overall discomfort

This is why staying in only ONE rep range for too long can eventually become limiting.

Not necessarily because the muscles stop responding…

But because fatigue starts accumulating in different ways.

A big part of long-term progress isn’t just creating stimulus.

It’s managing fatigue well enough to keep adapting over time.

The idea that the “first set is the most productive” has been gaining some traction lately.

And there’s certainly some truth to that.

The first hard set of an exercise may indeed provide the bulk of the training stimulus.

Which is why many coaches now advocate:

• fewer sets per exercise
• more exercise variation
• higher frequency per muscle

The idea being:

➡️ more “first set exposures.”

But here’s the issue…

Not every lifter produces their BEST output on the first set.

Some lifters become more confident under load, express more force across sets, and move more efficiently as the exercise progresses.

So while the first set may still be highly stimulative…

trying to constantly reset the exercise to chase more “first sets” may actually leave stimulus on the table.

Because for these lifters, some of their highest-quality sets may happen later in an exercise.

And no this isn’t always solved by simply doing more warm-up sets.

For some people, several progressively harder working sets are what actually allow them to reach peak output.

These lifters often do better with:

• fewer exercises
• more sets per exercise
• enough exposure to reach their best performance

The mistake is assuming everyone responds best to the same set structure.

Some lifters are ready from set one.

Others need several sets before they reach peak performance.

More “first sets” isn’t always better.

Over time, the same training stimulus produces less and less return.

That’s because your body becomes better at tolerating it.

The disruption is lower.

The signalling response is lower.

And eventually the adaptive response is lower too.

This is essentially what adaptive resistance is.

Your body becomes more efficient and less responsive to the same input.

Switching up exercises or adding more volume can work for a little while...

But eventually you start accumulating fatigue faster than you accumulate adaptation.

That’s when the niggles start showing up.

Performance becomes less stable.

Motivation drops.

And progress slows despite doing more work.

Sometimes the smartest thing you can do isn’t pushing harder…

it’s restoring sensitivity to the stimulus before the next push phase.

This is one of the most important lessons I learned over the course of my coaching career.

And it has played a major role in shaping my coaching philosophy.
