Katy Perry's Roar could be the secret to staying on track with your excercise resolutions.

Spotify has revealed a list of the tracks topping gym-goers' playlists across the globe with Eminem, Britney Spears and Pitbull among those featuring.

It has also unveiled the ultimate workout playlist based on the popularity of tracks coupled with scientific analysis of the songs that will make you sweat harder in the gym.

The music streaming service analysed over 6.7 million workout playlists globally and Can't Hold Us by Macklemore and Ryan Lewis was the most popular choice followed by Wake Me Up by Avicii, 'Till I Collapse by Eminem and Don't You Worry Child by Swedish House Mafia.

Men work out more frequently during the latter part of the week and feel the burn to a range of music from classic tracks such as Eye of the Tiger by Survivor and Eminem's aptly named 'Till I Collapse.

Data reveals more women opt for a morning workout over men's lunchtime trip to the gym.

Women are choosing to sweat it out at the beginning of the week with modern classics such as Rihanna's We Found Love. And women have a greater tendency than men to exercise in time to the beat.

Spotify has partnered with the Music in Exercise and Sport Group at Brunel University in London to create the ultimate workout playlist based on tempo (BPM), style and lyrical content.

"When synching your movements to the beat of the music, increase the intensity of your workout by raising the music tempo by one or two BPMs beyond your comfort zone - this will increase your workrate with the added benefit that the difference in effort will be almost imperceptible," the university's Dr Costas Karageorghis said.
