Why Group Training Gets Better Results — And What the Research Says
There's something that happens in a room full of people moving together. The energy shifts. You stand a little taller, push a little harder, breathe a little deeper, maybe add a heavier spring. If you've ever had a reformer class at Love Pilates that left you feeling more alive than your solo home workout, you're not imagining it — science has been quietly proving this for decades.
You Work Harder Without Even Realising It
In 1965, psychologist Robert Zajonc coined the term social facilitation to describe a well-documented phenomenon: people perform better in the presence of others. It's one of the most replicated findings in social psychology, and it applies directly to exercise. Simply being around other people who are working hard raises your own effort — often without you even noticing.
In a Pilates class, this plays out in subtle but powerful ways. When the person next to you holds their plank for one more breath, you do too, when they change to a heavier spring - suddenly you’re thinking you should too.
The Köhler Effect: Your Classmates Make You Stronger
A 2012 study published in the Journal of Sport & Exercise Psychology explored what researchers call the Köhler effect — the tendency to work harder when exercising alongside someone who is slightly fitter than you. Rather than feeling defeated, participants were motivated by the gap. The result? Workout duration increased by around 24% compared to exercising alone.
This doesn't mean you need to compete with anyone. It means being in a well-matched group naturally lifts your baseline. The person next to you in class isn't your competition — they're quietly making you better.
Accountability Changes Everything
One of the biggest predictors of long-term fitness results isn't intensity — it's consistency. (I’m not making this up when I say it in class!) And group training dramatically improves consistency.
When you book into a class, people expect you to show up. Your instructor knows your name. Your regular classmates notice when you're not there (trust us, we get asked where you’ve been by your class mates when you haven’t been for weeks). That social commitment makes it much harder to talk yourself out of a session (and getting out of bed early!) on a tired Tuesday morning. Over time, this compounds into real results.
Moving Together Amplifies Your Endorphins
In 2009, researchers at Oxford University studied rowers and found something remarkable: rowing in sync with teammates raised pain thresholds significantly more than rowing alone. The conclusion was that synchronised movement amplifies the release of endorphins — the brain's natural feel-good chemicals — beyond what individual effort produces.
This is why that post-class buzz at Love Pilates hits so differently. You've moved in sync, breathed together, and your nervous system has responded accordingly. (You might have also complained together!)
Enjoyment Is the Ultimate Performance Enhancer
Across the research, one variable keeps emerging as the strongest predictor of long-term exercise adherence: enjoyment. People who enjoy their workouts stick with them. It's that simple.
I’m not suggesting you enjoy every minute of Love Strong, but you enjoy the camaraderie, the group energy (and the results!). Group exercise consistently scores higher on enjoyment than solo exercise in self-report studies. That’s why lots of us prefer to push ourselves in Love Strong rather than heading solo to the gym. The social connection, the shared energy, the sense of belonging — these aren't soft extras. They're the engine behind lasting change.
What This Means for Your Pilates Practice
At Love Pilates, we've always known that community is at the heart of what we do. But it's worth knowing that when you sit down on your favourite reformer (yes, we know lots of you have favourites), next to your Pilates bestie, you're not just sharing a space — you're actively improving each other's results.
Whether you're a long-time Pilates Lover or thinking about your first class, the research is clear: you'll push further, stay more consistent, and enjoy it more when you move with your people.
