The Rise of the Functional Trainer: How the Home Gym Changed After COVID

For decades, serious strength training usually meant going to a commercial gym. Home gyms existed, of course, but for many people they were little more than a bench, a few dumbbells, perhaps a barbell and whatever equipment could fit into a basement or garage.

Then 2020 changed everything.

When COVID-19 forced gyms around the world to close, millions of people suddenly had to figure out how to train without access to the equipment they had always relied on. Living rooms became workout spaces. Garages became weight rooms. Dumbbells, benches, resistance bands and racks became difficult to find as demand for home fitness equipment surged. Retailers were reporting dramatic increases in home-equipment demand within weeks of the shutdowns.

What initially felt temporary eventually changed the way many people thought about training.

When the Gym Suddenly Came Home

At first, people improvised.

A pair of dumbbells and a bench could cover the basics. Resistance bands replaced some cable exercises. Online workouts became commonplace. In fact, the American College of Sports Medicine ranked online training as the number-one fitness trend for 2021, after it had ranked only 26th the previous year... a dramatic shift largely driven by gym closures and the move toward exercising at home. 

But as the months passed, many lifters wanted more.

They missed cable rows. Lat pulldowns. Triceps pushdowns. Face pulls. Cable flyes. Pullover movements. Adjustable resistance angles.

They wanted the exercise variety of a commercial gym without filling an entire basement or garage with commercial gym machines.

That problem helped create the perfect environment for the modern functional trainer.

People Discovered That Training at Home Wasn't Just a Compromise

Something unexpected happened once people had spent enough time training at home.

Many realized they liked it.

There was no commute. No waiting for equipment. No searching for matching dumbbells. No adjusting a machine after the previous person. No crowded locker room and no need to structure a workout around the busiest hours at the gym.

You could simply walk downstairs or into the garage and train.

A one-hour workout no longer needed to become a two-hour event once driving, parking and changing were included.

And your gym was always open.

That convenience remained valuable even after commercial gyms reopened. The pandemic may have forced people into home training, but it also gave millions of people enough time to discover that a properly equipped home gym could be a legitimate long-term alternative. Contemporary reporting at the time already noted that people who had invested in equipment were reconsidering whether they needed to return to their old routines.

Then Came the Biggest Home-Gym Problem: Space

Building a home gym creates a completely different set of priorities from training in a commercial facility.

Commercial gyms can dedicate hundreds of square feet to individual machines.

A homeowner usually cannot.

A dedicated shoulder press machine takes space.

A lat pulldown takes space.

A low row takes space.

A pec deck takes space.

A cable crossover takes space.

A pullover machine takes even more space.

Add enough dedicated machines and suddenly the garage has no room for the car.

This changed the value equation for home gym equipment.

It was no longer simply about asking:

“How good is this machine?”

The better question became:

“How many exercises can I perform with the amount of space this machine occupies?”

And that is where the functional trainer began to make a tremendous amount of sense.

Why the Functional Trainer Fits the Modern Home Gym

A functional trainer uses adjustable cable columns that allow resistance to come from many different heights and angles.

Move the pulleys high and you can perform pulldowns, pushdowns and straight-arm movements.

Move them to chest height and you can perform presses, flyes, rows and rotational exercises.

Move them low and you have curls, lateral raises, squats, lunges and countless other movements.

Stand closer to the machine and one resistance profile is created.

Step farther away and the exercise changes again.

Instead of buying another machine every time you want another movement, you change the pulley position, attachment, bench position or your own body position.

That adaptability is what makes the functional trainer so well suited to the home gym.

One Machine, Hundreds of Possibilities

Perhaps the biggest advantage of cable training is that the machine itself doesn't completely determine the exercise.

With a traditional selectorized machine, the path is largely predetermined.

Sit in a shoulder press machine and you shoulder press.

Sit in a leg extension and you extend your legs.

A functional trainer works differently.

The cable provides the resistance. You determine what to do with it.

And once people started building more sophisticated home gyms, attachments became an important part of that equation.

A rope creates one group of exercises.

Independent handles create another.

A straight bar changes the movement again.

Specialty cable machine attachments can then make movements possible that would otherwise be awkward or, require an entirely separate machine.

Suddenly the functional trainer isn't simply a cable machine.

It becomes a platform.

The Attachment Revolution

This has also helped fuel an enormous variety of functional trainer attachments and cable machine accessories.

Home-gym owners have become increasingly creative about finding ways to reproduce commercial-gym exercises using the equipment they already own.

Rather than buying a machine for every movement, they can often add an attachment.

That is a very different philosophy of gym building.

For example, the Andreoni Bar was developed around this same concept: using the adjustable resistance of a functional trainer to create movements that aren't always easy to reproduce with conventional cable attachments.

Neutral-grip shoulder pressing is one example.

Assisted dips are another.

Cable lat pullovers, lat prayers, rows, curls, pushdowns and numerous pressing variations can all be created by changing the cable position, body position and starting height.

The goal isn't necessarily to replace every dedicated machine.

It's to give the equipment you already own more possibilities.

The Home Gym Became Personal

There is another advantage that became increasingly obvious during the home-gym boom.

Your home gym can be built around you.

You choose the equipment.

You choose the attachments.

You choose the music.

You decide how everything is positioned.

And perhaps most importantly, you can choose exercises based on how they feel to your body rather than simply performing whatever machine happens to be available.

That can be particularly valuable for experienced lifters.

After decades of training, many people have movements they love, movements they tolerate and movements their joints simply don't enjoy anymore.

Cable machines provide tremendous flexibility to adjust grip, resistance direction, starting position and range of motion.

That makes experimentation much easier.

Adjustable Resistance Without Loading Plates

Convenience is another reason functional trainers have become so attractive.

Changing the resistance on a selectorized weight stack can take seconds.

Move the pin.

Train.

Want to increase the load?

Move the pin again.

Want to perform a drop set?

Reduce the weight and immediately continue.

There are no plates to unload and no dumbbells scattered around the room.

For supersets, drop sets and higher-volume training, that can make workouts considerably more efficient.

The Best Equipment Is Equipment You Actually Use

Perhaps the biggest lesson from the home-gym movement is that convenience matters more than many people previously realized.

Having world-class equipment ten kilometres away doesn't necessarily help if finding the time to get there is difficult.

Equipment that is twenty steps from your kitchen is different.

A quick workout suddenly becomes possible.

Thirty minutes is enough time to train because there isn't another thirty minutes of travel involved.

Miss the morning workout?

Train at night.

Have twenty minutes between commitments?

Go downstairs.

That accessibility can make consistency easier... and consistency remains one of the most important ingredients in long-term training.

COVID Started the Experiment. Convenience Kept It Going.

The home-fitness boom began largely out of necessity.

Gyms closed, people were isolated, and anyone who wanted to continue training had to find another solution. Home fitness equipment sales surged, and the industry rapidly adapted to people exercising outside traditional gyms.

But what started as an emergency solution became something much bigger.

People discovered that training at home offered privacy, convenience, flexibility, time savings and complete control over their training environment.

As those home gyms became more sophisticated, the emphasis increasingly shifted toward equipment capable of performing more exercises within less space.

And that is exactly where the functional trainer shines.

The Future of the Home Gym Is Versatility

The modern home gym doesn't necessarily need dozens of machines.

It needs equipment that earns the space it occupies.

A rack can become the foundation for barbell training.

An adjustable bench can support dozens of exercises.

Dumbbells cover hundreds more.

And a well-equipped functional trainer can provide an enormous range of cable-based movements from a relatively small footprint.

Add the right cable machine attachments, and that versatility expands even further.

The pandemic may have introduced millions of people to home training out of necessity.

But the lasting lesson was much simpler:

You don't necessarily need more equipment to build a better gym. Sometimes you simply need more ways to use the equipment you already have.
