Stuck in the pool? What your training week leaves out

You swim regularly. You do your lengths. You even feel like you are "working hard". And still, your 100 m has stopped moving. So has your 400 m. The session feels as hard as ever, or worse: flatter and flatter.

It is almost never a motivation problem. It is a structure problem. Most leisure swimmers and triathletes train in a grey zone: not easy enough to recover, and not hard enough to improve. And they forget the most underestimated tool in progress: the unload week.

The grey-zone trap

Picture an effort scale from 1 to 10. A lot of swimmers spend 80% of their time between 5 and 7: "a bit strong", "I worked", "I really sweated".

The problem: at that intensity you stack fatigue without a clear stimulus that forces the body to adapt. You are not slow enough to build deep endurance. You are not fast enough to improve your threshold or your speed.

In coaching this is called polarization: most of the volume should be truly easy (conversation pace, Z1/Z2), and a small part truly demanding (threshold, VO2, speed). The middle, that grey zone, should stay rare.

If every session looks the same, you plateau. Not because you are not doing enough. Because you always do it *the same way*.

A week that improves has several jobs

With 2 to 4 sessions a week, each slot needs a clear intention. A typical example with 3 sessions:

Session A, endurance / base A pace that is truly easy. You should be able to think about something else, even talk between two breaths. The goal: clean volume, a stable stroke, active recovery. This is the base, and it is often the session people spoil by swimming it too fast.

Session B, quality (threshold or speed) Here you work. Controlled sets, send-offs, target paces. The effort is strong but steady: you want even times, not a blow-up on the first length.

Session C, technique + moderate volume Short drills, then swimming that uses them. Not two kick blocks in a row. Not a whole session of drills either. ForSwim favours applying the work (kick, clean front crawl), not a swim-school class.

That variety creates the contrast the body needs. Without contrast, there is no adaptation.

Why you raise the volume, then you lower it

Progress is not swimming more every week, forever. A simple rule that lasts: do not raise volume by more than about 10% from one week to the next. Past that, the risk of fatigue and of a stroke that falls apart shoots up.

Even with a gradual rise, the body needs windows of recovery. That is what unload weeks are for: about every 4 weeks, you drop the volume clearly (often around -30%), and you keep a little light intensity so you do not "switch off".

During an unload week you do not "lose" your fitness. You absorb the work of the weeks before. The adaptations (more capillaries, a more economical stroke, tolerance at threshold) settle when the load comes down, not only when it goes up.

Signs you need an unload: - your set times drift, while the pace still feels "normal" - you already arrive tired at the warm-up - motivation drops for no clear reason - you have been stuck for 3-4 weeks, even though you have been showing up

What a good unload week is not

It is not a zero week. Stopping completely, then going hard again, creates a useless yo-yo.

It is not "swim less, but faster" either. An unload week mainly cuts volume and density. You can keep a few short touches of quality, but the idea is not to turn the week into a time trial.

And it is not laziness. The swimmers who improve for the longest are often the ones who dare to slow down at the right moment.

How to use this from tomorrow

1. Sort your next 2 or 3 sessions: which one is truly easy? Which one is truly hard? If you cannot answer, you are probably in the grey zone. 2. On endurance, make yourself slow down. If you finish a so-called "easy" session out of breath, it was not easy. 3. On quality, aim for even times. 6×100 m at steady times beats a brilliant first repeat followed by a collapse. 4. Plan an unload every 3 to 4 weeks: -25 to -35% volume, the same session shape, moderate intensity. 5. Measure. A reference 100 m or 400 m every 4-6 weeks tells you whether the structure is working. The feeling of that one day does not.

The link with a structured plan

Doing this by hand is possible, until life gets in the way. One missed session, one heavy week, and the polarization disappears.

That is exactly what a well built plan automates: distinct jobs for each session, a reasonable rise in volume, unload weeks built in, and paces matched to your 100 m, not to an imaginary average swimmer.

If you are stuck, the question is often not "am I swimming enough?". It is: does my week still mean something?
