From Barack Obama’s gym sessions with Nina Simone and Beyoncé to Dwayne ‘The Rock’ Johnson’s Iron Paradise playlist featuring 2Pac, Metallica, and Rage Against the Machine, music has the power to transform and energize.

Ronny Ho, a Spotify executive, knows this well. 

She curates Spotify’s Beast Mode playlist, providing the soundtrack to millions of sweat sessions each month. 

While her friends know she works at Spotify, they’re unaware of her pivotal role in crafting one of the most popular gym playlists. 

Build Strength and Conditioning With One Simple Tool
FULL-BODY TRAINING

If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

  • Full-body training with one weight using swings, squats, and presses
  • Solid cast iron build that feels stable and lasts for years
  • Comfortable grip that makes high-rep workouts easier to handle

Ho’s work underscores a growing trend: the science of using personalized music to boost workout performance.

The Power of Music in Fitness

Music’s impact on exercise is undeniable. It can delay fatigue, elevate mood, enhance cognition, and make workouts feel easier.

Essentially, music acts as a legal performance-enhancing drug. In fact, three out of four UK gym-goers rely on music during their workouts to gain this advantage.

The Need for Personalized Music

Antony Stewart, digital fitness director at Johnson Digital, emphasizes the importance of tailored music.

Generic gym playlists can’t compare to the benefits of music specifically curated for individual workouts. Spotify’s Beast Mode, used by five million people monthly, exemplifies this approach.

“Music needs to be specific and tailored – and more than just background noise,” Stewart explains. Tailored music offers a significant edge over generic gym-floor tunes.

Spotify’s Beast Mode: A Case Study

Ronny Ho transitioned from a career in finance to music curation at Spotify in 2016.

By October 2020, she was working on Beast Mode, keeping her involvement low-key to gather genuine feedback from friends. The playlist targets millennial and Gen Z men, featuring high-energy hits to pump iron to.

Beast Mode is a prime example of an ‘algotorial’ playlist, blending human editorial insight with algorithmic precision.

“A personalized playlist means we select a pool of tracks, and it’s different for every user based on their listening experience,” Ho explains. This personalized approach ensures each user gets a unique, motivating workout soundtrack.

Scientific Insights on Music and Exercise

Professor Costas Karageorghis, a sport and exercise psychology expert, has been studying the link between music and exercise for over 30 years.

His work includes tailoring motivational music for athletes like Team GB’s 400m hurdler Dai Greene before the 2012 London Olympics.

Currently, Karageorghis is exploring three key areas: combining music with virtual or augmented reality to enhance exercise enjoyment, using music to influence brain activity during workouts, and examining music’s role in high-intensity exercise.

At very high intensities, music doesn’t significantly reduce pain because the mind is focused on survival.

However, it can still have a general motivational effect. Surprisingly, Karageorghis advises athletes to train without music occasionally to maximize its benefits. “Two workouts with music to one without” helps prevent desensitization, ensuring music remains a potent workout aid.

The Future of Personalized Workout Music

Karageorghis envisions a future where gym environments use sensors to create real-time personalized music playlists.

This technology, which already exists, could revolutionize how music enhances group workouts by adjusting to the intensity and needs of the participants.

Practical Applications: BeatFit and PureGym

Last November, PureGym, with over 350 locations and 1.5 million members, faced a challenge: unregulated music selection across its sites.

Enter Antony Stewart with the BeatFit app, designed to align music with specific workout phases. By differentiating music for working and resting periods, BeatFit helps people train harder without realizing it.

Stewart’s experiments demonstrated that carefully curated music reduces perceived exertion, making workouts feel less taxing.

A scheduled meeting with PureGym aims to showcase the app’s potential, highlighting music’s untapped resource in fitness.

Pump It Up

Music’s ability to transform workouts by making them more enjoyable and less taxing is especially valuable for those who struggle with motivation.

As technology and research continue to evolve, personalized music could become a standard tool for optimizing gym performance.

Whether you’re a casual gym-goer or a serious athlete, the right playlist might just be the key to unlocking your full potential.
