You know that feeling when you’ve told yourself you’ll exercise tomorrow, and tomorrow comes, and somehow it’s still tomorrow. It’s not laziness. It’s the quiet way life gets in the way, and the lack of anyone else expecting you to show up. For a lot of people in their sixties and seventies, the difference between intending to move and actually doing it comes down to one thing: whether someone else is waiting.

Group exercise participants were 85% more likely to maintain their routines at six months compared to solo trainers, according to a study in the Journal of the American Osteopathic Association.

Group fitness classes work not because the exercises are better, but because the social contract is harder to break than a promise you made to yourself. When you know someone will notice you’re missing, showing up becomes simpler.
Why the group changes what you do
There’s a well-documented effect called social facilitation. It was first noticed in 1898, when a researcher called Norman Triplett found that cyclists rode faster when racing against others than when racing against the clock alone. The same principle applies in a church hall, a community centre, or a leisure centre studio. Being around other people who are working at something raises your own effort, often without you noticing.
But the more practical reason group classes work is simpler. A scheduled class at a set time on a set day creates a commitment that’s harder to talk yourself out of. You’ve paid, you’ve booked, and someone has planned the session around you being there. That structure matters more than most people realise. Research on implementation intentions shows that specific time-bound plans are two to three times more effective than vague intentions like “I’ll exercise more this week.”
There’s also something called the Köhler effect. It’s the finding that the weakest member of a group will work harder to avoid letting the team down. You’ll quit on yourself long before you’ll quit on a group of people you’ve come to know. One study found that exercisers paired with a virtual partner who was slightly more capable increased their workout duration by 24%. With a real person beside you, the effect is even stronger.
What happens in the body when you move together
Moving in time with other people does something unusual. Synchronised physical effort triggers the release of oxytocin, the hormone involved in bonding and trust. That’s why a class that starts with a room of strangers can end, forty-five minutes later, with people chatting and laughing. The shared effort has created a social connection that wouldn’t have happened if everyone had been on their own machine in a corner.
There’s also evidence that group exercise releases more endorphins and endocannabinoids than doing the same workout alone. One study in the International Journal of Stress Management found that group exercisers reported 26% lower stress levels than those who trained solo. The neurochemistry of shared effort is genuinely different from solitary effort.
And it’s not just about feeling better in the moment. The Oxford Institute of Cognitive and Evolutionary Anthropology found that synchronised group exercise increases pain tolerance compared to individual effort. That means you can sustain a higher intensity for longer when you’re moving with others. Your body literally lets you do more.
Getting started without overdoing it
If you haven’t been to a class in years, or never have, the idea can feel intimidating. It shouldn’t be, but it’s worth being practical about how to approach it.
If you have high blood pressure, joint issues, or any condition that affects your balance or heart, get medical clearance before starting any class. Some conditions mean certain movements are off limits.
Go and watch a class, or speak to the instructor about what’s involved. Most instructors are happy to talk through the format and tell you what modifications are available.
Look for classes labelled “gentle,” “seated,” “over-50s,” or “beginner.” These are designed for people who aren’t looking to be pushed to their limit.
A good instructor will check in with you, show you modifications, and keep an eye on your form. They want you to come back.
Classes that are too advanced for your current fitness level. An elite running club or a high-intensity bootcamp can overwhelm a novice and lead to injury or discouragement. Be honest with yourself about where you are, not where you wish you were.
It’s also worth giving it time. Research suggests it takes four to six weeks for the social bonds in a group to form properly. The first couple of sessions might feel awkward. That’s normal. The point is to keep going long enough for the group to become familiar.
What to look for in a class
Not all group classes are the same, and not all will suit you. The instructor matters more than the type of exercise. A good instructor is knowledgeable, engaging, and able to offer alternatives for different abilities. They should notice if someone is struggling and adjust without making a fuss.
Class size matters too. A small class of eight to twelve people allows the instructor to give individual attention. A large class of thirty can be high-energy but may leave you feeling anonymous. There’s no right answer, but it’s worth trying both to see which keeps you coming back.
Try at least three different classes before deciding it’s not for you. The first class is often about getting your bearings. The second is where you start to relax. The third is where you’ll know whether the format and the people suit you.
The type of class matters less than the consistency it creates. A seated yoga class you attend twice a week for six months will do more for you than a high-intensity class you attend twice and then stop. Some popular options for this age group include gentle Pilates, chair-based exercise, walking groups, and low-impact circuit classes. The common thread is that they’re structured, predictable, and social.
Many leisure centres and community halls offer discounted rates for block bookings or for people over a certain age. Some also offer a free trial session. It’s worth asking.
Options worth considering if you want to try it at home first
Not everyone wants to walk into a room full of strangers. Some people prefer to build confidence at home before joining a group, or they live somewhere where classes aren’t easily accessible. If that sounds like you, there are options that mimic some of the structure and guidance of a class without requiring you to leave the house.
The AeroPilates Reformer 287 is a home Pilates machine that slides rather than using springs. It’s low-impact, works the core and limbs, and folds away for storage. It comes with workout DVDs, so there’s a guided element to it. Reviewers say it’s easy to assemble and surprisingly compact when folded. It’s not a class, but it gives you a structured routine to follow at your own pace.
The Gorilla Bow Resistance Band System is another option. It’s a portable resistance system that replaces a full set of weights. It comes with multiple bands and handles up to 300lbs of tension. Reviewers note that it does squats, rows, curls, and chest press, and that the bands are durable. It’s compact and can be used while following online classes or videos, which gives you the structure of a guided session without the social pressure.
Both of these are tools, not solutions. The solution is the routine you build around them.
Narrowing it down to what fits your situation
The right choice depends on what you’re trying to solve. If the problem is that you don’t show up, the answer is probably a class with other people. If the problem is that you don’t know what to do, the answer might be a guided programme at home.
Online fitness communities can also provide accountability. Apps like Strava or Meetup have groups for walkers, runners, and cyclists of all abilities. Some people find that a virtual check-in with a group chat is enough to keep them consistent, even if they exercise alone.
| Attribute | In-person class | Home with guided equipment |
|---|---|---|
| Accountability | High — others expect you | Moderate — self-directed |
| Social connection | Direct and immediate | Limited or virtual |
| Cost | Per session or block booking | One-off purchase |
| Flexibility | Fixed times and locations | Any time, any place |
| Guidance | Live instructor feedback | Video or app-led |
- Group classes work because the social commitment is harder to break than a private promise. Missing a session feels like letting others down, not just yourself.
- The neurochemistry of shared effort is real — synchronised movement releases bonding hormones and increases pain tolerance, making exercise feel more rewarding and sustainable.
- Start with a beginner class, give it four to six weeks for the social bonds to form, and don’t be afraid to try different formats until you find one that fits.
Closing thoughts
Nobody needs to be told that exercise is good for them. The question is how to make it stick. For a lot of people in later life, the answer turns out to be other people. Not because they need motivating, but because showing up for someone else is simpler than showing up for yourself.
If you’re curious, try a class. If that feels like too much, try a guided home option like the AeroPilates Reformer or the Gorilla Bow. The important thing is to find a structure that gets you moving regularly, not to find the perfect one on the first try.
You know your own body better than any article does. Trust that. And if you find a class where people notice when you’re not there, hold onto it.
