Breathing is the foundation of life – that’s obvious.
But breathing technique during strength training is a topic that often gets overlooked.
Yet how and when you breathe during exercise impacts not only the effectiveness of your workout but also your safety.
A bad habit?
Training “silently”.
Many people feel embarrassed to breathe loudly in the gym.
But suppressing your exhale can have serious consequences – just like bottling up emotions, right?
When to inhale and when to exhale?
The rule is simple – exhale during the hardest part of the movement.
Examples:
- Squat – inhale when lowering down, exhale when standing up.
- Deadlift – inhale when leaning toward the bar, exhale during the lift.
- Bench press – inhale as you lower the bar, exhale as you push it up.
- Pull-up – inhale in the hang, exhale as you pull up.
- Leg raises over the head (one of my favorites) – inhale before raising and before lowering. In extreme cases (the movement has two phases), exhale both when lifting and lowering.
Breathe dynamically but with control.
Don’t hold your breath for long – unless you’re intentionally using the Valsalva maneuver (more on that below).
What happens when you breathe incorrectly?
Holding your breath under strain causes a rapid spike in blood pressure!
Studies show that during intense effort with breath-holding, systolic pressure can reach 300 mmHg.
That’s a massive load on the cardiovascular system.
Symptoms of poor breathing technique:
- dizziness or black spots in vision,
- red, swollen face,
- sudden sweating,
- feeling of pressure or lack of air in the head.
People with excess weight are especially at risk – their intra-abdominal pressure is already elevated at rest.
Without proper exhalation, the risk of fainting increases.
Risk of injury
Poor breathing is not just uncomfortable – it can be dangerous.
Common issues include:
- inguinal or umbilical hernia – from strong pressure with no exhale,
- lower back pain – due to lack of core stabilization,
- fainting or loss of balance – lack of oxygen to the brain.
What about psychology? Why do people “train quietly”?
It’s surprisingly common.
People suppress their breath because they don’t want others to hear them panting, hissing, or exhaling.
They’re ashamed to sound like they’re “fighting”.
But… that sound is a sign of real work!
Proper training has a sound.
An exhale through pursed lips or a subtle hiss isn’t a mistake – it’s stability, tension, and safety.
“Breathe – your body isn’t strong when it’s quiet. It’s strong when it’s aware.”
– strength coaches say this for a reason.
What about the Valsalva maneuver?
It’s a technique involving a short breath hold during exertion to increase intra-abdominal pressure.
It’s used by professionals (e.g., during record-setting deadlifts), but it’s not recommended for most recreational lifters.
It’s better to use a controlled exhale through tight lips – it offers similar stabilization but with much lower risk.
The Valsalva maneuver isn’t a powerlifter’s trick – it’s a ticking time bomb for your eyes.
Every time you inhale and hold your breath while tensing your muscles, you trigger the so-called Valsalva maneuver. It may help stabilize your core, but it comes at a cost: a sharp rise in pressure inside your chest, your head… and your eyes.
This seemingly harmless reflex can cause your intraocular pressure to spike by tens of mmHg – just enough to worsen optic nerve damage in someone at risk of glaucoma. And let me remind you – glaucoma doesn’t hurt. It doesn’t scream. It doesn’t warn you. It just silently destroys your vision, piece by piece. Irreversibly.
Over 50? Family history of glaucoma? Elevated eye pressure? This isn’t “nonsense for the weak” – this is a real danger. Just a few months of breath-holding during training can be enough for your next eye exam to deliver very bad news.
Don’t get caught off guard. Breathe. Because strong muscles mean nothing if you can’t see where they’re taking you.
Summary – breathe with awareness
Breathing technique during strength training matters.
It gives you more power, better control, and helps prevent injuries.
Don’t be ashamed to exhale.
It’s better to breathe audibly and safely than to train silently and dangerously.
Final tip: Inhale as you prepare for the movement, exhale during exertion.
