Muskeln-der Motor des Organismus

What if the internal organs were merely the servants of the muscles? That, at least, was a premise of Werner Kieser. A bold assertion. And one that initially irritates. After all, the heart or brain are considered the central organs of our body, while muscles are often reduced to movement, posture, or appearance. Kieser turned this perspective around. Not out of a desire for provocation (or maybe?), but out of functional thinking. His premise was: muscles are the engine of the organism. They demand performance, create need, and set the pace. The internal organs respond to it. They supply, regulate, dispose. They serve. This is not a biological detail argument, but a thought model.

The Importance of Strength Training: Why Muscles Are the Key Players

And as with all premises, the rule is: if you accept them, suddenly much becomes logical.

• Why muscles need to be regularly stressed.
• Why strength training is not just one form of exercise among many, but a form of basic care.
• And why targeted, measurable exertion is more important than as much movement or as varied stimuli as possible.

Meaningful exertion instead of rest: Responsibility for the body

This perspective stands in stark contrast to today's fitness and health culture. There, one often talks about "being active," "moderate exercise," or "cardiovascular health." All correct - but often without a clear hierarchy. Kieser's premise establishes exactly this hierarchy: Without resilient muscles, the system lacks the drive. This perspective is particularly enlightening when it comes to the topic of ageing - now often referred to as "longevity." We talk a lot about ageing organs, about declining functions. Less about the fact that muscles often are no longer challenged as we age. But what happens to a system whose clients no longer give orders? Perhaps organs do not first become weaker because they are ageing. Maybe they age because their central task is missing.

Kieser premise tolerates no arbitrariness. If muscles are central, they must be trained purposefully and systematically. Not as a lifestyle, but as a responsibility towards one's own body. Not to look better, but to keep the system functioning. Maybe that is precisely the real provocation of this premise: That health does not arise from avoidance, but from appropriately applied stress. And that our muscles are more than mere bystanders. They are the clients. The rest will follow.
