How to Learn Bilateral Breathing in Freestyle: Methods, Pros, and Cons

Introduction

There are two main ways to breathe in freestyle: unilateral breathing, where you always breathe to the same side at fixed intervals, and bilateral breathing, where you breathe every 3 strokes, alternating sides. Bilateral breathing is the foundational training method most recommended by competitive swimming coaches, because it forces swimmers to maintain balanced stroke mechanics on both sides, avoiding body misalignment and technical asymmetry caused by habitual breathing to one side. This article will explain in detail the advantages, challenges, and learning methods of bilateral breathing.

Advantages of Bilateral Breathing

1. Maintains Body Symmetry
Many swimmers habitually breathe only to the right (or left) over long periods, causing the stroke on the breathing side to become distorted—excessive head rotation, early hand exit, or excessive body roll. Bilateral breathing forces both strokes to be executed fully, helping to correct asymmetry issues.

2. Improves Directional Awareness (Especially in Open Water)
In long-distance and open-water swimming, swimmers who breathe to only one side tend to drift off course due to asymmetric strokes. Bilateral breathing allows swimmers to observe both sides of the environment when breathing, keeping a straight swimming line.

3. Handles Multiple Race Scenarios
During races, there may be distractions such as direct sunlight on one side or opponents swimming on a particular side. Swimmers who can breathe to both sides have greater adaptability.

Disadvantage: Reduced Breathing Frequency

The most obvious drawback of bilateral breathing is breathing only every 3 strokes (compared to every 2 strokes with unilateral breathing), which can lead to insufficient oxygen during high-intensity swimming. This is also why elite swimmers typically switch to breathing every 2 strokes in the latter part of a race to ensure adequate oxygen supply.

Steps to Learn Bilateral Breathing

Step 1: Confirm Breathing Mechanics on the Non-Dominant Side

Many people find that when breathing to their non-dominant side, head rotation feels awkward or they swallow water. First practice head rotation while standing to confirm that neck rotation range is similar on both sides, then move into the water to practice.

Step 2: Single-Arm Breathing Drill with a Kickboard

Hold a kickboard with one hand and pull with the other, practicing breathing to the non-dominant side during the pull. This reduces movement complexity and allows you to focus on the coordination between head and body on the breathing side.

Step 3: Transition Period with Breathing Every 5 Strokes

If breathing every 3 strokes feels too suffocating right away, you can first practice breathing every 5 strokes (LRRRL… where L/R represents the breathing side), allowing your lung capacity to gradually adapt to a lower breathing frequency.

Step 4: Full Bilateral Breathing Every 3 Strokes

Maintain a relaxed swimming pace, breathe consistently every 3 strokes, and feel the alternating breathing rhythm. It’s fine to be slow at first; the key is building the technique.

Breathing Strategy in Races

In competition, pure bilateral breathing is not necessarily the fastest. The recommended race breathing strategy is:

• Early stage (first 1/3): Breathe every 3 strokes, control the pace, stay relaxed
• Middle stage: Breathe every 2–3 strokes depending on how you feel
• Late stage (final 25–50 meters): Switch to breathing every 2 strokes to ensure adequate oxygen supply and sprint at full effort

Practical Advice

1. Consistently use bilateral breathing during training: Even if it feels more tiring, stick with bilateral breathing in training and adjust flexibly during races.
2. First correct the stroke on your non-dominant side: The stroke on the breathing side is most prone to distortion; it is recommended to specifically practice the full stroke on the non-dominant side.
3. Do not force breath-holding: If you truly feel uncomfortable, immediately switch to breathing every 2 strokes—do not let your technique completely fall apart by pushing through.
4. Long-term persistence is required for results: Switching from unilateral to bilateral breathing typically takes 4–8 weeks to feel natural; short-term discomfort is a normal adaptation process.

Conclusion

Bilateral breathing is one of the most beneficial long-term habits in swimming technique training. Although it may feel uncomfortable at first, with consistent practice you will find your stroke becomes more balanced, your swimming line straighter, and you will have greater flexibility in handling various race situations.
