Somewhere between your third set of deadlifts and the moment you go slightly purple in the face, you might wonder: should I actually be breathing right now? It's one of those gym questions nobody wants to ask out loud, like wondering if you're using the Smith machine correctly (you're probably not).
According to a piece over at Lifehacker, the answer is a satisfying "it depends" - which is fitness journalism's version of a mic drop.

The case for holding your breath
Here's the nerdy part: when you hold your breath and brace during a heavy lift, you're creating something called intra-abdominal pressure. Think of your torso like a soda can - the more pressurized it is, the harder it is to crush. That pressure acts as a natural support brace for your spine, which is genuinely useful when you're trying to hoist something embarrassingly heavy off the floor.
This technique - exhaling against a closed airway, basically - is a real thing powerlifters and strength athletes use intentionally. It's not just forgetting to breathe because you're terrified of the barbell.

The case for, you know, breathing like a human
Here's where it gets spicy. Holding your breath dramatically spikes your blood pressure. For healthy people doing a few hard reps, that's generally fine. For anyone with cardiovascular concerns, hypertension, or a history of certain health conditions, it's a much bigger deal - and worth an actual conversation with a doctor rather than a Reddit thread.
For casual gym-goers doing moderate weights, the standard advice still holds up: exhale on the exertion (the hard part), inhale on the return. It keeps oxygen flowing, keeps your form from getting sloppy, and prevents that fun dizzy spell when you stand up too fast after squats.

So what should YOU do?
If you're a recreational lifter doing sets of 10-15 with manageable weight, just breathe. In and out. Like a person. Revolutionary advice, truly.
If you're going heavy - we're talking near-maximal effort, low reps, the kind of lift where you briefly consider your life choices - the breath-hold technique has real merit. Just don't make it a habit on every single exercise across your whole workout, unless you enjoy seeing stars for non-fun reasons.
The takeaway is less "stop holding your breath" and more "understand why you're doing it." Accidental breath-holding from anxiety or bad habit? Work on that. Intentional bracing on a PR attempt? Arguably valid.
Either way, maybe stop going quite so purple. That can't be good for anyone.
