More Buoyancy, More Speed

Many swimmers try to get faster by pushing harder. But the biggest performance lever is often somewhere else: your body position in the water.

And this is exactly where a factor comes into play that many underestimate – buoyancy.

If you lie better in the water, you swim more efficiently, conserve energy, and automatically become faster.

What does buoyancy mean in swimming?

Buoyancy describes how well your body is supported in the water. The better your buoyancy, the higher your body stays at the surface.

The goal is a horizontal body position – without sinking legs or unnecessary drag.

Why buoyancy is so important

Many underestimate how much body position affects speed.

• Poor body position = high drag
• Good body position = less drag + more efficiency

The difference is significant: with the same effort, you can swim much faster simply by improving your position in the water.

Body position and drag

As soon as your legs start to sink, additional drag is created. Your body works against the water instead of moving smoothly through it.

A stable, high body position allows you to glide efficiently – with less energy loss.

Efficiency over power

Especially in open water, it’s not about applying maximum force.

It’s about swimming efficiently. The more energy you save, the more you have left for cycling and running.

Buoyancy is one of the easiest ways to become more efficient immediately.

How a wetsuit improves your buoyancy

A wetsuit supports you exactly where many swimmers struggle: body position.

• Additional buoyancy in the hips and legs
• More stable position in the water
• Reduced energy loss

This allows you to swim more efficiently without having to completely change your technique.

Explore all wetsuits designed for performance in open water.

Common mistakes

Many try to improve their speed by increasing power – while ignoring body position.

• Too much effort with poor positioning
• Sinking legs
• Unstable body alignment

The better approach: first optimize your position in the water, then increase intensity.

Frequently asked questions

Can buoyancy be trained?

Partly, yes – mainly through technique. But the fastest improvements often come from external support in the water.

Is more buoyancy always better?

For beginners, usually yes. Advanced swimmers also focus on balance and flexibility.

Why do my legs sink in the water?

Often due to body tension and positioning – this is exactly where additional buoyancy helps.

Conclusion: More buoyancy doesn’t just mean more comfort – it means more speed.
