Uncensored music in the gym has been proven to increase performance!

Anyone who exercises regularly knows that the right playlist can work wonders. It will energize you, help you overcome fatigue and make your workout fun. But have you ever thought that the version of a song - the censored version, or the one with the original, "edgy" lyrics - can affect how much you lift? Science says yes. And the difference is bigger than you'd expect.

"Bleeped" lyrics = weaker performance

A groundbreaking 2025 study titled "Effects of Censoring Explicit Language in Music on Resistance Exercise Performance" focused on this exact question. Researchers compared two groups of athletes: one listened to uncensored songs, the other to the same songs but with "bleeped out" swear words.

The results were clear. The group that listened to the censored versions

• Did fewer repetitions.
• She felt less motivated.
• Rated the training as more challenging.

In contrast, the athletes with the original, uncensored lyrics in their ears performed noticeably better and felt better about the workout.

Why do bad words work as "doping"?

The explanation lies in how our brains respond to music and emotionally charged words. Explicit lyrics act as a trigger that activates a number of processes in the body:

• They increase adrenaline levels and heart rate, which prepare the body for maximum performance.
• They improve concentration as the brain processes more emotional and cognitive stimuli.
• They distract from pain and discomfort, allowing you to push beyond fatigue.

Censored songs blunt this mental advantage. "Beeps" disrupt the flow and energy of the song, reducing the aggression and predation needed during demanding sets.

It's not just one study

Older research confirms this effect. Back in 2015, a study (Zareian et al.) showed that songs with any lyrics reduce perceived exertion compared to instrumental versions. A 2022 study (Stephens et al.) went even further and found that simply repeating swear words can temporarily increase grip and arm strength. This is due to what is called psychological disinhibition - a mental "switch" that releases inhibitions and allows the body to reach its bottom.

What do you take from this?

Although these studies are smaller in scale, their results are consistent: explicit music provides athletes with a psychological and physical advantage.

So the next time you're making a playlist for the gym, don't be afraid to reach for original, uncensored versions of your favorite songs. If you're lifting more with them, it's not just in your head. Science is backing you up!
