THIS PLAYLIST WILL MAKE YOU FITTER Science says so

The key to lifting heavier and running faster? It’s all in your scientifically engineered Spotify playlist

What you do in the gym is hard. It’s also not natural. Think of it – all that cycling on a stationary bike to nowhere while a woman in small Lycra pants with a stomach like a bag of onions shouts at you. Think of all those leg presses and tricep dips you try to do while maintaining the bare minimum of human dignity. It’s tough on the gym floor, which is why not just any old playlist is going to cut it. No, what you need is a playlist that corresponds with what your brain (and body) needs for maximum motivation. Thankfully, someone has spent the past 25 years researching this first-world dilemma. His name is Dr Costas Karageorghis, sports psychologist at Brunel University, and he has basically analysed every chart hit of our time to find the ultimate fitness songs. These are his favourites. Prepare to smash that PB.
