Should I be making noises of effort while doing an exercise at the gym? And why or why not?

Picture this: You're at the gym, pushing through that last set of squats, and a guttural grunt escapes your lips. Heads turn, eyebrows raise—is this helping your workout, or just annoying everyone around you? The debate over making noises of effort, like grunting or heavy breathing, during gym sessions is as old as fitness itself. From the subtle exhale to the full-on roar, these sounds are common in weight rooms worldwide. But should you be vocalizing your exertion? And does it actually make a difference? Drawing from scientific studies, expert opinions, and real gym-goer experiences, we'll explore the pros, cons, and etiquette of gym noises. Whether you're a silent sufferer or a vocal victor, understanding the why behind the grunt can transform how you approach your workouts.

Gym noises aren't just random—they're often instinctive responses to physical strain. As we'll see, they can serve practical purposes, but they also come with social and health considerations. Let's dive in and separate fact from fiction.

What Are Gym Noises of Effort, and Why Do They Happen?

Noises of effort refer to the sounds people make during intense exercise, such as grunting, groaning, heavy exhaling, or even yelling. These aren't deliberate attempts to draw attention (usually); they're physiological reactions. When you lift heavy weights or push your limits, your body naturally tightens the core and forces air out, creating sound. 8 Think of it like a tennis player's grunt during a serve—it's part of the explosive effort.

Physiologically, grunting involves the Valsalva maneuver: holding your breath, bearing down, and then exhaling forcefully. This stabilizes the spine and increases intra-abdominal pressure, potentially allowing for more force production. 11 But is this always beneficial? We'll unpack that next.

The Benefits: How Noises Can Boost Your Performance

Surprisingly, science suggests that making noises during workouts can give you an edge. A 2025 study highlighted in Women's Health found that grunting during high-intensity efforts amplifies strength by facilitating a sharp, forceful exhale. 0 Researchers believe this exhale recruits more muscle fibers and enhances power output, similar to how martial artists use kiais (shouts) to focus energy.

Small studies, as reported by The New York Times, indicate that grunting improves strength, striking power, and oxygen utilization. 1 For example, a 2018 study in PLOS ONE showed that grunting increased force production in tennis players by up to 5%. 2 In the gym context, this could mean squeezing out an extra rep on the bench press or deadlift.

Psychologically, noises serve as a mental boost. Fitness coach Jeff Nippard explains that grunting can help you "psych up" and push through pain barriers. 7 It's like a battle cry that signals to your brain: "We're going all out!" Actress Kate Hudson has shared that her workout grunts help her power through tough sessions, providing a psychological edge. 6

Equinox's fitness experts note that grunting stretches skeletal muscles, increases potential energy, and protects the spine during heavy lifts. 5 For compound movements like squats or overhead presses, this core stabilization can prevent injuries and allow for heavier loads.

In competitive settings, grunting might even distract opponents. A study from PMC found that simulated grunting led to slower, more error-prone responses in adversaries. 2 While not directly applicable to solo gym sessions, it underscores the power of vocal exertion.

Overall, if done right, noises can enhance performance by combining physical mechanics with mental motivation. But moderation is key—let's look at the flip side.

The Drawbacks: When Grunting Goes Wrong

Not all grunts are created equal, and excessive noise can backfire. Etiquette is a big issue—gyms are shared spaces, and loud noises can distract or intimidate others. Quora users often complain that excessive grunting seems like attention-seeking rather than genuine effort. 8 In crowded facilities, this can create tension or even lead to complaints.

Health risks exist too. Improper grunting, especially holding breath too long, can spike blood pressure and strain the heart. A Newsweek article warns that while grunting boosts force, it's best reserved for elite athletes to avoid cardiovascular strain. 10 Happiest Health points out that grunting doesn't always help lift weights and might lead to injuries like hernias if the technique is off. 11

For beginners, grunting might mask poor form. If you're vocalizing to compensate for bad technique, you're risking injury without real gains. Stylist magazine notes that while grunting can increase force, it's not a substitute for proper breathing patterns. 4

Socially, over-the-top noises can make the gym feel unwelcoming, especially for women or newcomers. A YouTube video by fitness experts discusses how grunting divides gym cultures—some embrace it as passion, others see it as rude. 12 The consensus? Keep it controlled and necessary.

Expert Opinions: What Do Trainers and Scientists Say?

Fitness pros are divided but lean toward moderation. DMoose's experts affirm that grunting helps push through heavy lifts by stabilizing the core. 7 Healthshots adds that while not necessary, it can positively impact strenuous workouts. 13

However, researchers like those in a 2018 study caution that benefits are small and context-specific. 10 The New York Times concludes that while grunting aids oxygen use and power, the mechanisms aren't fully understood, and silent breathing might suffice for most. 1

Trainers recommend learning proper breathing: Inhale during the eccentric phase (lowering), exhale during concentric (lifting). If a grunt naturally occurs on the exhale, fine—but don't force it. For cardio or lighter sets, stay quiet to focus on rhythm.

When to Grunt and When to Stay Silent

Context matters. For heavy compound lifts near your max, a controlled grunt can help. In group classes or quiet gyms, opt for subtle exhales. Here's a quick guide:

Yes to Noise: During PR attempts, powerlifting, or HIIT bursts where force is key. 3
No to Noise: In yoga, light cardio, or crowded spaces where it disrupts others.
Moderate Approach: Use breath sounds that aid effort without echoing through the gym.

Real gym stories vary: Some love the energy of vocal workouts, others prefer peace. Balance personal benefit with courtesy.

Gym Etiquette and Alternatives to Grunting

To avoid dirty looks, follow unwritten rules: Keep volumes reasonable, apologize if excessive, and respect gym norms. Many facilities have "no excessive noise" policies.

Alternatives include focused breathing techniques like pursed-lip exhales or mental mantras. These provide similar stabilization without sound. 4 Wear headphones to zone in, or train during off-peak hours for freedom.

Conclusion: Grunt Wisely for Better Workouts

Making noises of effort at the gym isn't mandatory, but it can enhance performance when used strategically. Benefits like increased force, psychological boosts, and spinal protection make it worthwhile for heavy efforts, backed by studies showing small but real gains. 0 However, drawbacks including distractions, health risks, and etiquette breaches mean it's not for every set or situation. Experts agree: If it helps you lift safer and stronger, go for it—but keep it controlled. Ultimately, your workout is about progress, not performance art. Listen to your body, respect others, and find what works for you. Who knows? That subtle grunt might just be the key to your next personal best.
