Is more always better?

Quick answer
No. In almost every training parameter—volume, frequency, intensity, duration—gains diminish as you add more, while costs continue to rise. The optimal point is well before the maximum.

TL;DR

• Diminishing returns apply to every training variable, without exception.
• The cost, however, remains linear: more time, more fatigue, more risk.
• There is, therefore, a point where doing more causes you to lose more than you gain.

The question

"If two sessions work, four would work better, right?"

The logic seems sound. It relies on a rarely stated assumption: that the relationship between effort and results is proportional.

It never is. And understanding why changes how you structure a year of training.

What physiology says

Gains decrease, costs do not.

This is the principle that governs everything else. Each additional set produces less than the one before it. Each added hour yields less than the previous one. Conversely, each set costs the same amount of time, fatigue, and tissue strain.

You end up with a benefit curve that flattens out and a cost curve that climbs straight up. They inevitably cross.

The phenomenon repeats at every level.

Volume: four weekly sets per muscle group already produce substantial gains, and adding more yields diminishing returns.

Frequency: at an equal volume, spreading work over four sessions rather than two makes practically no difference.

Intensity: stopping one to three repetitions before failure produces almost as much as going to the limit, with significantly less fatigue.

Duration: beyond an hour of actual work, alertness drops and the quality of the final sets declines.

The same pattern, four times.

And overdoing it comes at a double cost. First, immediately, through fatigue and time spent. Second, later on, when the accumulation hinders recovery, promotes tendinopathy, and eventually leads to a complete stop.

The deceptive thing about this belief is that it isn't entirely false. More training does indeed produce more results. It’s just that the relationship isn't proportional—it’s poorly proportioned. That is what makes it so difficult to correct.

An analogy

A company that doubles its advertising budget does not double its sales.

The first few dollars reach the easiest customers to convince. Subsequent ones target more distant, less receptive audiences. Past a certain threshold, you pay a high price to reach people who will never buy.

No CFO thinks in terms of "always more." They think in terms of marginal return: what the next dollar spent will yield, not the total spent.

Your training deserves the same reasoning.

What we observe at the studio

The people who get the best results over five years are never the ones who do the most over three months.

We regularly see people arrive with the intention of training five times a week. They last three weeks, sometimes six. Then fatigue sets in, the sessions decline in quality, some discomfort appears, and the whole thing falls apart. Six months later, they have lost more time than they gained.

Those who build something lasting do the opposite. They start below what they are capable of, they keep some margin, and they only increase the intensity once the foundation is stable.

That is also the studio's logic: two well-structured sessions rather than five improvised ones. Not because it’s more comfortable, but because it’s what produces the most over a decade.

The question is never "how much can I do," but "how much can I do every week for ten years."

What this changes for you

Seek efficiency, not the maximum. The right question is what the next added session brings, not the accumulated total.

Leave yourself some margin. A program sized to your maximum capacity won't survive the first difficult week.

Only increase once the foundation is stable. If you aren't yet reliably managing two sessions a week, adding a third will only increase the number of missed sessions.

Beware of periods when you feel like you can do anything. That is when people add too much, and that is when things break.

Judge by the year, not by the month. What matters isn't the peak, it's the sum.

The best program isn't the one that makes you progress the fastest. It's the one that is still around in three years.
