Listening to music on the bike is a controversial topic (though you can get purpose designed headphones which let in outside sounds) but most of us like to get our pedal on to music when training on the turbo or at the gym.
Music can be a great motivator - everyone's got different tastes, but of course there are some clear favourites that really get people moving.
Every month, musical workout site Run Hundred collect favourite songs from 40,000 jiving gym goers, and rank them in order of popularity. Using that information, they've complied 2015's most popular workout songs based on a total of 128,000 people's votes.
All songs are assigned to a 'zone', determined by the beats per minute that will match the music best, so you can make sure your music matches your effort level perfectly.
Without further ado - here's the official Run Hundred Top Ten, starting from ten and working towards the ultimate number one....
Demi Lovato – Confident – 130 BPM
The American singer released this as the second single on her fifth studio album of the same name - and we have to admit we do love the bad ass bass-ey beat. A song about "empowerment and confidence" we reckon this is a good place to start!
The Magician - Sunlight feat. Years & Years - 122 BPM
And now for something completely different! This is a dance song to get you moving, and actually we can imagine it working pretty well with some out-the-saddle spin class efforts...
Sorry about all the slow-mo bum shots...
Andy Grammer – Good to Be Alive (Hallelujah) - 120 BPM
A great one for morning workouts, we can imagine ourselves signing along to this on one of those early spring sessions where the sun is finally starting to shine through the winter depression...
Icona Pop – Emergency – 126 BPM
This upbeat track comes from the Swedish electropop duo Icona Pop and we love the trumpet chorus and the subtle beat beneath it that could certainly be timed with high-resistance out-the-saddle pedal strokes...
One Direction -Drag Me Down - 139BPM
Are these the ones supported by Beliebers? Oh, no, we've got it wrong again, haven't we?
Boy band jokes aside, the lyrics "nobody can drag me down" make a pretty call mantra for those hard hill reps! Go smash it! (and we do expect your heart rate to be over 139 bpm by now!)
Walk the Moon – Work This Body – 135 BPM
A happy clappy tune, the confrontational lyrics create a juxtaposition that can't fail to rile up your competitive nature.
It's not clear if we're talking about tennis or a metaphorical court - but our favourite line has to be this - plain and simple: "One day I will beat you fair and square, show me what you got..."
Who do you want to be racing this season?!
Jess Glynne – Hold My Hand – 123 BPM
UK number one in March, this is one to lift your spirits during the damp and dreary January days where you're not sure exactly why you decided to get out of bed for an early morning session.
The motivational lyrics to listen for are "I'm ready for this" - and hey, you could always substitute the romantic tone and imagine it's your bike "can't walk alone" without!
Kelly Clarkson – Heartbeat Song (Nebuer Remix) – 135 BPM
"This is my heartbeat song" is a great one to chant along as you watch yours rise (though again, really we want you getting over 135 bpm in those efforts!).
This remix puts a faster, dancier spin on the January 2015 single - and we can totally imagine getting our sweat on to it..
Katy Tiz – Whistle (While You Work It) – 162 BPM
Tough intervals ahead? As the lyrics say: "Gotta smile while you're hurting / And whistle while you work it" - at the end of the day, the benefits you reap come summer racing/sportives/club runs/other will be well worth every pedal stroke! Katy knows best!
Mark Ronson & Bruno Mars – Uptown Funk (Dave Audé Remix) – 124 BPM
And here we are - we've reached number one! This feel good tune will help you get through the toughest of rides - surely?!
