Stronger Together: The Science Behind Training With Other People
Why exercising with others could improve your motivation, performance and long-term success
Have you ever noticed that a run feels easier when you're chatting with someone?
Or that you're much less likely to skip a workout when someone is expecting you to turn up?
Maybe you've found yourself running a little quicker during a group session than you would have on your own, or pushed out one more repetition simply because someone was beside you doing the same.
If so, you're not imagining it.
Training with other people doesn't just make exercise more enjoyable—it can genuinely change how your body and brain respond to it.
Whether it's a running club, group fitness class, sports team, training partner or personal trainer, exercising alongside others has been shown to influence motivation, consistency, enjoyment and even performance.
The science suggests that sometimes the biggest improvement you can make isn't changing your training programme.
It's changing who you train with.
We Are Wired to Move Together
Humans have always been social.
For thousands of years, we survived by working together—hunting, gathering, building and protecting one another.
Movement was rarely something we did alone.
Although modern exercise looks very different, our brains still respond positively to shared experiences.
Training with others can increase enjoyment, improve confidence and make difficult sessions feel more manageable.
In many ways, movement is not just physical.
It's social.
Accountability Changes Behaviour
One of the biggest reasons people struggle with exercise isn't knowing what to do.
It's doing it consistently.
It's easy to cancel a workout when nobody knows you planned to go.
It's much harder when someone is waiting for you.
That simple sense of accountability can make a remarkable difference.
Knowing that your training partner, coach or running group expects to see you often provides just enough motivation to get out of the door, especially on the days when motivation is low.
And as we've discussed in previous blogs, consistency is what drives long-term results.
Sometimes, showing up is the hardest part.
Having someone else there can make that first step much easier.
Why Exercise Can Feel Easier Together
One of the most fascinating areas of sports psychology is something called social facilitation.
It describes our tendency to perform better simply because other people are present.
Without consciously trying, we often:
run slightly faster
lift a little more
maintain effort for longer
stay focused
push through discomfort more effectively
We're not necessarily competing.
We're responding to the environment around us.
Have you ever noticed that a difficult run passes more quickly when you're chatting with someone?
Conversation provides a distraction from discomfort, making the effort feel more manageable.
The workout hasn't become easier.
It just feels easier.
Motivation Is Contagious
Motivation isn't something we either have or don't have.
It can be influenced by the people around us.
Training alongside positive, encouraging people often increases our own enthusiasm and confidence.
Seeing someone complete another repetition, finish a difficult interval or achieve a personal best can make our own goals feel more achievable.
Success has a way of spreading.
So does enthusiasm.
That's one of the reasons communities often achieve more together than individuals do alone.
We Naturally Raise Our Standards
Whether we realise it or not, we often match the behaviour of those around us.
If everyone arrives on time, works hard and encourages one another, those behaviours quickly become the norm.
Likewise, if the group values consistency over perfection, that mindset becomes infectious too.
This isn't about unhealthy comparison.
It's about creating an environment where positive habits become easier to maintain.
Confidence Grows Faster Together
Walking into a gym or joining a running club for the first time can feel intimidating.
Many people worry that they're not fit enough, fast enough or experienced enough.
The reality is that most people have felt exactly the same at some point.
Training with supportive people helps remove that uncertainty.
Questions become easier to ask.
Mistakes become opportunities to learn.
Progress feels less daunting because you're not tackling it alone.
Confidence often grows through experience—but it also grows through encouragement.
It's Not Just About Performance
The benefits of training with others extend well beyond improving fitness.
Regular physical activity already supports mental wellbeing.
Adding a social element can make exercise even more rewarding.
Training with friends, teammates or a supportive community can help reduce feelings of isolation, improve mood and make exercise something you genuinely look forward to.
When exercise becomes enjoyable, it becomes sustainable.
And sustainable habits create lasting results.
Training Alone Still Has Its Place
Of course, not every session should be done with other people.
Solo training allows you to:
focus on technique
work at your own pace
reflect and reset mentally
complete recovery sessions without pressure
prepare specifically for individual goals
The key is recognising that different sessions have different purposes.
A recovery run doesn't need to become a race.
A strength session doesn't always require competition.
The best training plan often includes both independent sessions and opportunities to train with others.
Who Benefits Most?
The simple answer?
Almost everyone.
Beginners often gain confidence and accountability.
Experienced athletes benefit from shared effort and healthy challenge.
Runners maintain pace more easily.
Strength athletes often lift with greater intent.
Older adults can improve confidence, balance and social wellbeing.
Even elite athletes, despite competing individually, rarely train alone.
Because they understand that progress is rarely built in isolation.
🔬 The Science Behind It
Research in psychology and exercise science shows that our environment can have a powerful influence on how we perform and how consistently we exercise.
One explanation is social facilitation, the tendency to perform familiar tasks better when other people are present. Simply knowing that others are exercising alongside us can increase focus, effort and persistence.
Another important concept is self-determination theory, which suggests that people are more likely to stick with exercise when three basic psychological needs are met: autonomy (having choice), competence (feeling capable) and relatedness (feeling connected to others). Group training naturally supports that sense of belonging.
Exercise itself also stimulates the release of chemicals such as endorphins and dopamine, which contribute to improved mood and motivation. Sharing positive experiences with others may strengthen these effects and reinforce the habit of regular exercise.
Perhaps most importantly, studies consistently show that people who enjoy exercise are more likely to continue doing it over the long term.
And often, it's the people around us who make exercise enjoyable.
The Coached FITT Takeaway 🧡
Fitness is personal.
But it doesn't have to be lonely.
The programme you follow is important.
The exercises you choose matter.
But the environment you create matters too.
Sometimes the biggest difference isn't a new pair of trainers, a different workout or another piece of equipment.
Sometimes it's simply having someone beside you.
Someone who encourages you on the difficult days.
Someone who celebrates your progress.
Someone who reminds you to keep showing up.
Because while exercise changes your body, community often changes your relationship with exercise.
And when people enjoy moving together, they're far more likely to keep moving for years to come. 💪🧡
