Why Rocky Still Makes Me Cry

When the Rocky theme kicks in, a 55-year-old former boxer feels like he’s about to burst into tears, and there’s good science explaining why. Nobody has died. Nothing is wrong. And yet it happens every single time.

I was about four when I first trained on my own. Back garden, ball against the wall, ball off the fence, wee mazy runs while I imagined I was Kenny Dalglish playing for Celtic or Scotland. I didn’t know it then, but that was my first lesson in mental rehearsal and visualisation.

A few years later I was queuing round the block in my home town to see Rocky. That’s what you did before online booking. I can’t tell you for certain which friends I went with, but I can tell you exactly how that film made me feel.

At 17 I got serious about boxing and trained every day to fight competitively. I’ve never stopped training since. Now, with another Rocky film on the way and clips all over Instagram, the same thing happens whenever I hear the horns or see him sprint up those steps in Philadelphia: a wave of emotion that seems far out of proportion to a film clip.

So I went looking for what’s actually going on. The short answer is that four separate mechanisms are stacking on top of each other, and most of what they do to you is good.

The grades in this post: Strong means many studies agree. Moderate or Mixed means real but smaller or less consistent evidence. Plausible, untested means a reasonable explanation that hasn’t been tested directly.

1. Your brain on the theme tune

Peak moments in music engage the same reward circuitry that responds to food, sex and drugs. That’s not a metaphor. In 2001, researchers at McGill scanned people listening to music that gave them “shivers down the spine”, and found that, as the chills grew stronger, blood flow changed in the ventral striatum, midbrain, amygdala and orbitofrontal cortex. Some of these areas became more active and some less. All of them are involved in reward, motivation and emotion (Blood & Zatorre, 2001).

A decade later the same group measured dopamine directly. Using PET scanning, they showed dopamine release in the striatum at the moment of peak emotional arousal to music (Salimpoor et al., 2011).

The part I find most interesting is the timing. When they scanned the same listeners again with MRI, two different areas lit up at different moments. The caudate was more involved while people anticipated the peak, and the nucleus accumbens during the peak itself. Your brain knows the horns are coming. It starts the build-up before the music does.

That’s why the first few bars are enough. You aren’t reacting to the music so much as to what you know it is about to do.

2. Thousands of sessions: music wired to effort

For anyone who trained to it, that music isn’t just a memory of a film; it’s wired to the physical state of pushing yourself. I’ve lost count of the sessions I did with Rocky in my head or in my ears. Every one of them paired that music with adrenaline, a pounding heart, pain tolerance and the feeling of breaking through.

This is classical conditioning, the same principle as Pavlov’s bell. Repeat a pairing often enough and the cue alone starts to call up part of the response. So when the theme plays now, my body partly replays the arousal of a hard session, without the session to burn it off. That’s the “about to burst” feeling. Plausible, untested Established conditioning principles applied to one person: me.

The music was doing real work during those sessions too. A meta-analysis of 139 studies and 3,599 participants found that music during exercise improved mood, physical performance, perceived exertion and oxygen efficiency, with faster tempos giving larger performance effects (Terry et al., 2020). Strong The effects are small to moderate. A review of the brain research suggests music pulls attention towards external cues and keeps fatigue signals from reaching awareness (Karageorghis et al., 2018).

In other words, the music helped me train harder, and training harder made the music matter more. That’s a loop, and decades of it leave a deep groove.

3. Why age 15 hits hardest

Memories from adolescence and early adulthood are recalled more readily than those from any other period of life, and music is one of the strongest keys to them. Psychologists call this the reminiscence bump.

The music studies line up. In older adults, familiar songs brought back more memories from their youth than from any other time of life (O’Shea et al., 2025). Another study found that, once familiarity was taken into account, the peak covered music from adolescence (14 to 18) and even middle childhood (5 to 9), not just early adulthood (Kathios et al., 2024). These memories held up well even in a small study of people with Alzheimer’s disease (Baird et al., 2018). Moderate Consistent, but small studies, all in older adults.

That explains the slightly odd thing I noticed: I can’t reliably name who I went to the cinema with, but the feeling is crystal clear. Music-evoked memories tend to be less specific than memories cued by photos; they’re more often general knowledge or repeated events than single moments (Baird et al., 2018). The music doesn’t hand you a photograph. It hands you a mood.

And that mood is nostalgia, which people describe as a mixture of happiness and loss (Hepper et al., 2012). For me, part of the loss is a world before smartphones, when you queued for a film and talked about it all the way home. Part of the happiness is gratitude that I got to grow up then.

4. It isn’t sadness: Mickey and the mentor

The tears Rocky brings don’t look like sad tears. Researchers have proposed a distinct emotion for this, which they call kama muta, using a Sanskrit term. It often comes with tears, goosebumps and a warm feeling in the chest. Its trigger is a sudden intensification of closeness or belonging between people (Zickfeld et al., 2019, across 19 countries).

In a study tracking viewers moment by moment through six short videos, feeling moved rose and fell with perceived closeness, tearing up, goosebumps and chest warmth. It behaved differently from both happiness and sadness (Schubert et al., 2018). Moderate A newer field, mostly from the same research network.

Rocky is built from exactly those moments. An old trainer finally backing a nobody. Adrian standing by him. A man who doesn’t need to win, just to go the distance and prove he belongs. For me, Burgess Meredith’s Mickey hits hardest of all.

I think that’s because Mickey isn’t only a character to me. He’s every coach who believed in me before I’d earned it. And after decades of coaching boxers and training clients, he’s also the role I’ve spent most of my life trying to fill. At 15 I identified with Rocky. At 55 I think I’m watching Mickey.

There’s a bonus here too. Tearful people are seen by others as warmer, and that effect runs through being perceived as moved and touched (Zickfeld & Schubert, 2018). An earlier finding that tearful people also look less competent didn’t replicate in that study. People watching you well up at Rocky are more likely to think you’ve got a heart than think you’re weak.

Where it all started: AeroBox

For me, Rocky isn’t only tied to my own training; it was the opening track of my working life. When I was starting out, I ran a circuit class and a boxing fitness class. Boxercise and BoxFit were already franchises, so I called mine AeroBox.

I set it up myself, printed the posters and told everyone I met. On a good night there were 20 or more people jumping about, and every class started with the Rocky theme. This was before PPL licences, when you could play whatever got the room going. For shadow boxing combinations in the warm-up, Eye of the Tiger kept the rhythm. It might sound cheesy now, but back then it felt exactly right.

Some of the regulars, mostly middle-aged business types, wanted to go further and test their grit. So I started a separate sparring class. It was the Fight Club era, which gave it a fresh edge on top of the Rocky history. The point was to take a punch to the face and carry on, without tipping into anger or pointless violence. Most of the time, I was the human punch bag, letting them get a feel for it and bringing them on.

AeroBox became the way I built a network and a reputation for personal training, mostly strength and weight loss at first. Boxing also led me somewhere unexpected. In Joe Weider’s Muscle & Fitness I saw Oscar De La Hoya training by catching tennis balls while kneeling on a Swiss ball. That sent me into Swiss ball training, then to Paul Chek, who largely created that market. Through Chek came personalised nutrition and metabolic typing, and from there thyroid blood testing. That was the start of what I thought of as functional fitness and functional nutrition, and eventually of Test, Don’t Guess.

So when the theme plays, it isn’t just a 15-year-old in a cinema queue, or a boxer pushing through another round. It’s also a young coach with a stack of posters and a room full of people, building a business one person at a time. No wonder it lands so hard.

Is it good for you?

Mostly yes, in modest but real ways; the benefits come from letting the response happen rather than fighting it.

• Crying. A review of the evidence proposed that crying works as a self-soothing behaviour, helping restore balance after arousal, though whether you feel better depends on context and on how others respond (Gračanin et al., 2014). Mixed
• Nostalgia. In seven studies, nostalgia strengthened feelings of social connection, raised self-regard and lifted mood. It is also triggered by low mood and loneliness, which suggests it works partly as a natural pick-me-up (Wildschut et al., 2006). Nostalgic stories even pass these benefits on: young adults who read older people’s nostalgic memories reported more connectedness and meaning in life (Wildschut et al., 2018). Moderate Mostly short-term lab studies, largely by one research group.
• Music for training. Music lifts mood, improves performance and makes effort feel easier, and faster music gives the bigger boost to performance (Terry et al., 2020). In my experience, the music that carries the most weight is the music that’s yours.
• Holding it in has a cost. In a study of 180 women, those told to hide their feelings during sad and funny films showed increased sympathetic activation of the cardiovascular system. They also reported feeling less amused (Gross & Levenson, 1997). Moderate One classic study, women only, short film clips.

That last one matters for anyone who clenches their jaw at the cinema. Hiding the feeling doesn’t stop your body reacting. Your heart still works harder, and you may enjoy the film less.

Using it on purpose

If a piece of music reliably moves you, treat it as a tool rather than an embarrassment.

1. Build a short list of your own “Rocky tracks”. The music that matters is the music that’s yours, tied to your own memories and efforts. Generic gym playlists don’t carry that charge.
2. Use it to change state before hard sessions. A few minutes of it beforehand can shift mood and arousal, and fast music during the session tends to help performance.
3. Use it when you’re flat or lonely. Nostalgia seems to switch on in exactly those moments and push back against them. Music from your teenage years is one of the quickest routes in. (If loneliness is more than a passing mood, read Loneliness Is a Clinical Variable.)
4. Share it. Tell your kids, clients or training partners what the music meant to you and why. Nostalgia passes between generations, and the connection is half the benefit.
5. Let the tears come. If the feeling arrives, don’t throttle it. It’s a sign that the system is working, not that something is wrong.

The cinema question

I’ve genuinely wondered whether to see the new film on my own, so I’m not a grown man sobbing in public. I’ve decided that’s the wrong call.

Going with other people is half the experience. And the one classic study on this suggests that clamping down would cost me physiologically and make it less enjoyable. More to the point, that cinema will be full of people my age who queued for the original. I suspect I won’t be the only one reaching for a sleeve when the horns start.

If you’re the same, go with people you’re comfortable with, sit at the end of a row if it helps, and let it happen. Then go home and train.

How strong is the evidence?

The music and exercise findings are the strongest; the personal conditioning story is a reasonable explanation rather than a tested one.
