The Influencer Who Became the Gym

I came across Anna Engelschall through her Growingannanas account.

At first, it looked like the familiar fitness-creator formula: an extremely athletic person, a clean studio, energetic music and a seemingly unlimited supply of exercises that become painful after about forty seconds.

But the more I looked at the account, the less it resembled an influencer posting workout videos.

It looked like a gym.

There is no physical building. There are no receptionists, changing rooms, membership cards or rows of machines. There may not even be another person in the room when the workout is filmed. Yet millions of people arrive, follow the same instructor, complete the same movements and gradually build a routine around her.

The gym has been compressed into one person, one camera and a catalogue of videos.

A traditional gym begins with physical infrastructure. Someone rents a large space, fills it with expensive equipment and hopes that enough people living nearby will pay every month to use it. The business is constrained by location, capacity and opening hours. Even a successful gym can only fit so many people inside it at once.

A fitness creator begins with distribution.

Anna can record a workout once and have people complete it for years. One video is not merely content. It is a class detached from time and place. It can run simultaneously in bedrooms, hotels, offices and living rooms around the world. The next participant costs almost nothing to serve.

Her YouTube channel contains individual workouts, playlists and complete challenges. A fourteen-day challenge turns a sequence of free videos into something resembling a temporary training programme. The videos are public, searchable and endlessly replayable.

This makes the YouTube channel both the gym floor and its marketing department.

Someone may arrive through a search for a twenty-minute workout. They complete it, return the next day, subscribe and eventually begin following the creator rather than searching for individual exercises.

The relationship slowly changes.

The user is no longer choosing a workout.

They are choosing Anna.

This is where the creator gym becomes more powerful than a library of exercise videos.

Workout recordings have existed for decades. The instructor appeared inside the programme, but the company and distribution system usually existed elsewhere. A studio produced the tape. A television network owned the audience. A retailer sold the product.

The contemporary fitness creator combines all of these layers.

She is the instructor, performer, brand, marketing channel, distribution system and evidence that the programme works. Her body is simultaneously the product demonstration, the company logo and the case study.

The free workout is the beginning of the funnel.

Growingannanas now leads into the Grow app, which adds structured plans, recipes, habit tracking and community challenges. The app turns a loose public catalogue into an organised membership product. The website explicitly compares the product with both YouTube and the gym: the free videos provide workouts, while the paid layer provides structure, continuity and support.

Other large fitness creators have built almost exactly the same architecture.

Caroline Girvan keeps large free training programmes on YouTube, then places the fuller system inside CGX. The paid product adds exclusive programmes, scheduling, form guidance, meal ideas, education and progress tools.

MadFit places hundreds of YouTube workouts inside an app that reorganises them by style, duration and intensity. It adds structured programmes, recipes, tracking and additional trainers.

Pamela Reif has expanded from workout videos into an app, food, beauty products and a wider lifestyle brand.

These are not influencers who happen to have apps.

They are vertically integrated fitness businesses whose most visible interface is a person.

The creator produces the attention, owns the relationship and gradually builds products underneath it. Traditional companies usually work in the opposite direction. They create a product first, then spend money trying to find a face, a voice and a distribution channel that will make people care about it.

Growingannanas already has all three.

Her face creates recognition.

Her workouts create utility.

Her repeated presence creates familiarity.

Every free video strengthens the relationship that the paid product can later monetise.

There is something unusually efficient about this arrangement. A gym needs instructors, facilities, equipment, scheduling software, sales staff and a local reputation. The creator gym can initially operate with a camera, editing software and a person capable of performing the workout.

What would have been separate departments become different activities carried out by the same body.

This also changes what people are paying for.

The exercises themselves are not scarce. Squats, lunges and jumping jacks are not proprietary technology. Free training plans exist everywhere. An AI system can already generate a technically reasonable workout in seconds.

What is scarce is the willingness to begin, continue and return tomorrow.

The creator does not only explain the movement. She lends the user some of her energy. She performs the discipline that the viewer is trying to access. The countdown, music, facial expressions and carefully controlled intensity reduce the number of decisions the participant needs to make.

Pressing play temporarily transfers responsibility to someone else.

A personal trainer might say that the value comes from individual correction and adaptation. That is true, and a prerecorded video cannot fully replace it. But many people were never going to hire a personal trainer. They were choosing between doing nothing and following a person on a screen.

The creator gym is often good enough, immediately available and socially easier.

Nobody watches you enter.

Nobody notices that you do not know how the machines work.

There is no journey across town and no awkward first day. You can quietly fail at a movement, close the laptop and return later.

The absence of a physical gym is part of the product.

The creator also gives the workout a social surface. People comment that they finished day six, struggled with the final round or returned after an injury. A person training alone can see evidence that thousands of other people are performing the same private ritual.

The community is mostly asynchronous, but that may make it more accessible.

You do not need to arrive at 18:30.

You only need to press play.

This model has another advantage over the traditional gym. A physical gym often earns money from people not attending. The membership works partly because customers overestimate how often they will visit, then keep paying through inertia.

The creator gym has the opposite public incentive. The content has to keep being used because use creates views, recommendations, habit and the possibility of conversion into a paid product.

The user disappearing is not hidden profit.

It is a broken distribution loop.

That does not necessarily make the model morally superior. It creates a different set of pressures.

Compressing a company into a person creates a strange fragility.

A conventional gym can replace an instructor. Its brand can survive staff turnover, injury and ageing. A creator-led fitness company is more difficult to separate from the person at its centre. Her appearance, energy, health and continued willingness to perform are business infrastructure.

The creator must remain both relatable and aspirational.

Fit enough to represent the desired outcome, but approachable enough that the workout still feels possible.

Disciplined, but not joyless.

Intense, but supportive.

Personal, but scalable.

This is emotional and physical labour disguised as effortless consistency.

The body also becomes a public asset that everyone feels permitted to inspect. Changes in weight, muscle, age, pregnancy, injury or appearance can become business events. A normal fluctuation in someone's life may be interpreted as evidence about the effectiveness of the product.

The creator is selling a healthier relationship with the body while operating a company that may depend on the continuous commercial legibility of her own.

The product and its advertisement are the same body.

There is also the platform underneath the person.

These gyms do not own the streets leading to their front doors. YouTube, Instagram and TikTok decide how many people encounter the work. A change in recommendation systems can resemble a shopping centre suddenly moving a gym into the basement.

The app is partly an attempt to escape that dependency.

It converts followers into registered users and recurring subscribers. It creates a place where the creator controls more of the relationship. The free channel produces attention, while the app attempts to turn that attention into something more stable.

But people may still be joining because of the person rather than the programme.

This could be the real moat as fitness becomes increasingly automated.

An AI coach can produce endless personalised routines. It can adapt exercises, calculate progression, generate meal plans and send reminders at exactly the right time. It may eventually watch form through a camera and correct the movement more precisely than a prerecorded creator can.

What it cannot easily reproduce is years of accumulated trust in a specific human being whose body, personality and effort have become familiar.

The creator may become less important as a source of fitness information and more important as a reason to act on it.

This is why the strongest fitness creators do not feel interchangeable even when the exercises overlap. Caroline Girvan can offer structure and strength. Pamela Reif can offer polish and lifestyle. MadFit can offer accessibility and dance. Growingannanas can offer explosive energy and the feeling of joining a global workout already in progress.

The programme matters.

The person makes the programme feel alive.

Growingannanas is therefore not simply a fitness influencer.

She is a gym whose architecture is made from media.

The videos are its rooms.

The playlists are its programmes.

The app is its membership system.

The comment section is its communal floor.

Anna herself is the instructor, reception desk, billboard and building.

It is an astonishingly efficient company.

It may also be an exhausting way to become infrastructure.

AI authorship note

This essay began with Kris Haamer encountering Anna Engelschall's Growingannanas account, looking for comparable fitness creators and asking for the Raw Drafts angle. AI supported research into creator-led fitness platforms, drafting, editing, metadata and the publishing workflow. Kris selected the argument that the creator had become a vertically integrated global gym and approved this version for publication.
