It's common knowledge that listening to music whilst working out is motivational.
You often find that in those times of pain when you think you haven't got another squat or burpee left in you, your music speaks to you and spurs you on to dig deep and get the job done.
We all have our own personal tracks that we have in reserve for these desperate times (mine is Jess Glynne's Don't Be So Hard On Yourself) but what about the rest of your workout playlist?
Dr Costas Karageorghis, reader in sport psychology at Brunel University London and author of Applying Music in Exercise and Sport, has done the hard work for you and found the best motivational tracks that you need on your playlist to keep you going.
Dr Costas' seven tracks that will motivate you to keep moving...
Foo Fighters - Everlong
Tempo: 158bpm
From motivational lyrics to power chords, this track has everything you need to keep you going through those strength training sessions.
Plus, everyone loves a bit of Dave Grohl, right?
Fun - We Are Young
Tempo: 116bpm
Dr Costas calls this track a middle-of-the-road - it's not bad, but it's not great.
Exactly how you might feel during a core workout.
The steady beat and limited dynamic range, is perfect for distracting you from the burn in your abs but not so much that you lose form.
Who said abs weren't 'fun'?
Naughty Boy feat. Beyonce and Arrow Benjamin - Runnin' (Lose It All)
Tempo: 140bpm
This track was made for running playlists.
Not only do you have Beyonce commanding you to keep running (literally) but the tempo also allows you to hit a stride per beat.
You'll be breaking your personal bests in no time.
Blondie - One Way Or Another
Tempo: 161bpm
The legendary Debbie Harry will not only keep you in good company during your workout, but will also have you cycling at 80.5 rotations per minute.
That puts you on track to cycling around 15 miles in 40 minutes.
Your legs may be burning but one way or another you'll pull it out of the bag.
Prodigy - Run With The Wolves
Tempo: 166bpm
If you thought your run to Beyonce was fast, think again.
The Prodigy will have you sweating within minutes.
With a tempo of 166bpm, the heavy synths will drive you forward and keep you motivated to run through the pain.
Power - Kanye West
Tempo: 77bpm
Channel your inner strength and lift those weights to the syncopated beat - perfect for reps.
The short and sweet track will allow you to feel that burn without overdoing it.
R. Kelly - The World's Greatest
Tempo: 96bmp
Ok, so maybe a little too literal, self-congratulatory and cheesy.
But, this track is perfect for your cool down session.
With a slower tempo and a strong beat, you can feel good having completed your workout and knowing you are 'The world's greatest'.
