Over the past few months, I have noticed something changing in my body. My arms are often sore. My mobility and flexibility have gradually decreased, despite the stretching I regularly do. Even simple movements, such as reaching both hands behind my back, have become more difficult than they used to be. At times I also feel small but persistent discomfort around the area where the triceps meets the shoulder, together with a general sense of heaviness in both arms.

A different kind of soreness

This is not the kind of soreness that appears after one unusually hard workout and disappears two days later. It is subtler than that, but also more persistent. It comes and goes, changes intensity, and seems to sit in the background of my training.

That makes it harder to interpret. Is it simply the normal accumulation of training? Is it a sign that I am adapting? Or is it my body asking me to change something before a small problem becomes a larger one?

The difference between effort and accumulation

In a long-term endurance challenge, fatigue is not necessarily the enemy. Fatigue is part of the process. If the objective is to hold a straight-arm plank for a time that once seemed impossible, there must be stress, adaptation, repetition and progressive overload. There is no way around that.

But there is an important difference between being tired from a demanding session and carrying unresolved soreness from one session into the next. The first may be exactly what training is designed to produce. The second deserves more attention, especially when it begins to affect range of motion, comfort in daily positions, or the way the body feels before training has even started.

My recent sessions have made that distinction increasingly relevant. During August I have moved through repeated sets of four, five and seven minutes, longer continuous efforts, training on grass and on the beach, and even swimming on days when my arms were already slightly sore. Individually, none of those sessions appears extraordinary. Together, however, they create a volume of work that the body still has to absorb.

A body that keeps giving information

One of the lessons of this project is that the body communicates constantly. Sometimes the message is obvious: shaking arms, a burning abdomen, or the simple urge to stop. At other times the signals are less dramatic. Fingers go numb for a few seconds. A position that was previously comfortable becomes awkward. The shoulders feel less free. The arms remain heavy even on a day that was supposed to feel easy.

During one five-set session in early August, my arms only began to shake in the final four-minute interval. On another ten-minute continuous effort, some numbness appeared after about eight minutes and disappeared soon after finishing. In a later three-by-seven-minute workout, the first three fingers of both hands became numb, again resolving immediately once the session ended.

None of these episodes stopped me from completing the training, but together they form a pattern worth observing rather than ignoring. This does not automatically mean that something is wrong. It does mean that a training diary should record more than times, repetitions and personal bests. It should also record sensations, limitations, surfaces, temperature, recovery, sleep and the little details that often explain why two workouts with the same duration can feel completely different.

The temptation to prove something every day

When you are chasing a record, there is a natural temptation to turn every workout into a test. If the plan says twenty-four minutes of total volume, the instinct is to complete twenty-four minutes. If a session feels difficult, the instinct is often to prove that it can still be done. That mentality can be useful in competition. It is much less useful when it becomes the default attitude in training.

The world-record attempt is not tomorrow. The objective is not to win a single session in August. The objective is to build a body that, month after month, can tolerate more time in the position, recover from it, and return ready to train again. A successful workout is therefore not always the hardest workout. Sometimes it is the one that leaves enough capacity for the next step.

This becomes especially important as duration grows. Early in the project, an extra minute can feel like a small numerical increase. But each additional minute is added on top of everything that came before it. The challenge is not simply to endure longer. It is to make longer duration sustainable.

What does soreness actually mean?

Muscle soreness is often treated as proof that training worked. Sometimes it is simply the result of a new or demanding stimulus. But soreness alone does not measure the quality of an athlete's progress. A session can be productive without producing much soreness, and persistent soreness can sometimes mean that recovery is not fully matching the amount of work being accumulated.

For me, the practical question is not whether soreness exists. It is how it behaves. Does it improve after warming up? Does it disappear with rest? Is it symmetrical? Does it reduce mobility? Does it alter my plank position? Does it become more noticeable from one week to the next? These questions are more useful than simply deciding that soreness is either good or bad.

The discomfort around the arms and shoulder insertions is particularly interesting because straight-arm plank is a static position. There is very little visible movement, yet the upper body is under continuous load. The shoulders, triceps, forearms, wrists and stabilizing muscles work for minutes without the relief that comes from a normal repetition cycle. That type of sustained tension has its own cost.

The twenty-four-minute question

This brings me to the immediate decision: how should I approach a planned twenty-four minutes of volume when my arms already feel persistently sore? The answer is probably not to think of twenty-four minutes as a debt that must be paid at any cost.

Volume can be distributed. Recovery can be increased. The surface can be chosen carefully. The first repetition can become a diagnostic tool rather than the opening statement of a battle. If the movement feels normal and the soreness stays stable, the session may continue. If mobility worsens, discomfort becomes sharper, or the body feels clearly different from normal training fatigue, then reducing the session is not failure. It is information used correctly.

This is an important mental adjustment for me. I have always believed strongly in respecting the calendar. Consistency matters. A plan only has value if it is followed. But respecting a calendar does not necessarily mean obeying every number blindly. A good training plan must include the ability to interpret reality.

Recovery is part of the record attempt

Stretching has been part of almost every session, before and often after the plank work. Yet stretching alone does not guarantee recovery. The body also needs time, sleep, nutrition, variation and moments without load. In recent weeks I have been reminded that recovery cannot simply be added at the end of the training plan as an optional extra. It is one of the training variables.

This may be especially true for an athlete who is not twenty years old and who is pursuing an unusually specific endurance target. The objective is not only to become stronger. It is to remain healthy enough to train continuously for years. In that context, avoiding an unnecessary setback may be worth far more than completing one impressive session.

There is also a psychological challenge here. Rest rarely feels heroic. Cutting a set short does not create a satisfying number for a training log. Recovery produces no dramatic photograph. But the record, if it ever comes, will be the result of all the invisible decisions as much as the visible ones.

Discipline is not the same as stubbornness

One of the ideas I keep returning to is the difference between discipline and stubbornness. Discipline is following the process. Stubbornness is following one instruction even when the evidence has changed.

If I stop because a workout is simply hard, that teaches me very little. Hardness is expected. But if I modify a workout because multiple signals suggest that recovery is incomplete, that can be a disciplined decision. The difficulty lies in knowing which situation I am in.

There will never be perfect certainty. Training is full of incomplete information. The best I can do is observe carefully, record honestly and make decisions that serve the long-term objective rather than the emotion of the day.

The real meaning of One More Minute

The name of this project is One More Minute. At first, the phrase sounds like a command: hold on, resist, add another minute, do not stop. That is certainly part of its meaning. A record built minute by minute requires the willingness to stay in the position when the mind starts looking for an exit.

But I am beginning to think that One More Minute has another meaning too. It is not necessarily the minute I force into today's workout. It can be the minute that becomes possible next month because I trained intelligently this week. It can be the minute protected by a recovery day. It can be the minute earned by avoiding an injury that would have cost weeks.

The final record, if I reach it, will not be built by one spectacular act of toughness. It will be built by hundreds of small decisions: when to push, when to relax, when to change the surface, when to repeat a session, when to reduce volume, and when simply to accept that the body has the final vote.

The route must stay intelligent

For now, the soreness in my arms is part of the story. I do not want to dramatize it, and I do not want to ignore it. I want to understand it. Tomorrow's twenty-four minutes are therefore not just another workout. They are another opportunity to learn how to distinguish persistence from unnecessary force.

The goal remains exactly the same. The route toward it may need to be intelligent enough to change.

THE TAKEAWAYThe goal is still one more minute, but the route to that minute must include the courage to listen, recover and adapt.
