Should You Breath On One or Both Sides In Freestyle?

One of the most common questions among freestyle swimmers is:

“Should I always breathe to one side, or should I learn to breathe on both sides?”

The answer is not as straightforward as many swimmers think. While bilateral breathing (breathing to both sides) offers several technical benefits, unilateral breathing (breathing to one side) is also widely used, even at the highest levels of the sport.

Unilateral Breathing

Unilateral breathing refers to taking breaths consistently on the same side, typically every two strokes.

Advantages

• Provides more frequent oxygen intake.
• Feels more natural and comfortable for many swimmers.
• Helps maintain race pace, especially during sprint events.
• Allows swimmers to focus on power and rhythm without worrying about breathing patterns.

Potential Drawbacks

• May lead to over-rotation on one side.
• Can create stroke imbalances over time.
• May place additional stress on one shoulder or side of the neck.

Bilateral Breathing

Bilateral breathing involves alternating breathing sides, commonly by breathing every three strokes.

Advantages

• Promotes a more balanced stroke.
• Improves body alignment and rotation symmetry.
• Develops comfort and breathing ability on both sides.
• Particularly beneficial in open water swimming, where changing conditions may require breathing away from waves, sunlight, or competitors.

Potential Drawbacks

• Can feel challenging for beginners.
• Some swimmers may feel they are not getting enough oxygen.
• Requires time and practice to establish an efficient rhythm.

So, Which Is Better?

For beginner swimmers, learning to breathe on both sides is a valuable skill. It encourages balanced technique and helps swimmers become more adaptable in different training and racing situations.

For competitive swimmers, bilateral breathing can be an excellent training tool. However, during races, many swimmers choose the breathing pattern that allows them to perform at their highest level.

In fact, the majority of elite swimmers—including Olympians Michael Phelps and Katie Ledecky—primarily use unilateral breathing during competition. This demonstrates that there is no single “correct” breathing style for every swimmer.

A Practical Approach

A simple way to develop breathing versatility is to include both breathing patterns in training:

• 25m breathing to the right side
• 25m breathing to the left side
• 25m bilateral breathing (every three strokes)
• 25m normal freestyle

This type of drill can improve balance, body rotation, and overall breathing control.

The Bottom Line

Bilateral breathing is a valuable skill that every swimmer should learn. It promotes stroke balance, body awareness, and adaptability.

However, when it comes to racing, comfort and performance matter most. If breathing on one side allows you to swim faster, maintain better rhythm, and feel more relaxed, there is nothing wrong with using it.

The best breathing pattern is ultimately the one that helps you swim your fastest while maintaining efficient technique.

Learn both. Train smart. Race with what works best for you.

Happy Swimming!
