  • Breath-holding practice with a routine:
    • Example: Hold your breath for 30 seconds, then swim 25 meters underwater; increase time gradually.
  • Swimming a pool length without coming up for air:
    • Example: Swim one full pool length underwater at the end of your workout.

Why Lung Capacity Matters in Swimming?

Improving your lungs helps you not to become tired very soon and finish a lap very easily. When your lung capacity is high, you have more energy to finish a lap or more than that.

How to Increase Lung Capacity for Swimming? (Real Swimmer Experiences and Proven Methods)

These are the questions which the answers are very valuable:

How can interval training help lung capacity?

Many swimmers report that swimming hard, like swimming one lap very fast without coming up and breath for any stroke, then resting, and repeating 6 to 8 sets, has made a great difference.

if you go for practicing 3 times a week, you should do the interval 1 time. After a few weeks, you will see the difference.

Does underwater practice really work?

Initially, most swimmers struggle to swim for an extended period without taking a breath, but regular practice of underwater swimming helps build lung capacity. The practices are:

  1. At the end of each lap, push off the wall and swim the first 5–10 meters underwater before surfacing
  2. Try to swim the whole pool length without coming up for air
  3. Hold a kickboard and kick underwater for short distances to focus on breath control.

What about progressive breathing sets?

A lot of swimmers recommend starting by breathing every 3 strokes, then moving to 5, and finally 7. This will give you better focus in freestyle.

Are there dry-land exercises that help?

Yes. Some swimmers practice breath-hold walks or deep breathing exercises.

For example, one swimmer shared that walking while inhaling for 2 seconds and exhaling for 6 seconds trained their lungs to stay controlled in the pool.

Others combine these with yoga or meditation breathing to strengthen the diaphragm.

Final Thoughts

Learning how to increase lung capacity for swimming is about having the passion to continue your effort. By combining pool sets like underwater laps and progressive breathing drills with dry-land exercises such as diaphragmatic breathing and box breathing, you’ll quickly notice improvement.

Real swimmers confirm that these methods increase your lung capacity, breath control, and overall confidence.

With practice, you’ll not only expand your lung capacity for swimming but also improve your speed, endurance, and enjoyment of every swim.

FAQs:

  • Practice progressive breathing: Start by breathing every 3 strokes, then move to every 5 or 7 strokes.
  • Do underwater swims: Swim short or full pool lengths underwater to build breath control.
  • Try breath-hold progressions: Hold your breath for 30–60 seconds, then swim a short distance before breathing.
  • Mix pool and dry-land training: Combine water drills with box breathing or breath-hold walks outside the pool.

Holding your breath doesn’t actually make your lungs bigger, but it trains your lungs to use oxygen more efficiently and increases your tolerance to carbon dioxide.

Hypoxic swimming is when you intentionally limit how often you breathe while swimming. For example, instead of breathing every 2 strokes, you breathe every 5, 7, or even 9. This helps your body get used to low oxygen and use it when it's necessary. This is a good way to build lung capacity for swimming, but you should be careful cause you may feel dizzy or too tired.

Signs of low lung capacity can include:

  • Getting out of breath quickly, even with light exercise
  • Struggling to hold your breath underwater
  • Needing to breathe every 1–2 strokes in swimming
  • Feeling dizzy or fatigued during physical activity

Water should be the main drink, but green tea as an antioxidant, and ginger tea for inflammation reduction are recommended.

In 7 days, focus on:

  1. Do the diaphragmatic breathing every day for 10 minutes.
  2. Swim underwater without coming up and getting air.
  3. Try to run or ride a bike for 30 minutes every day.
  4. Between your practices, drink water.

These are the best steps in learning how to increase your lung capacity for swimming.
