Why Actors Should Train Their Bodies - And It Has Nothing to Do With How You Look

When we think about actors preparing for a role, we often think about learning lines, researching characters, developing emotional connections and rehearsing scenes. Physical training, on the other hand, is frequently associated with changing an actor's appearance.

But what if we approached training differently?

What if the purpose of building strength, endurance, mobility and coordination wasn't to look a certain way on camera, but to expand what we're capable of doing when the camera starts rolling?

An actor's body is one of their most important creative instruments. It's how they communicate, respond, move through a scene and bring a character into the physical world.

And just like any instrument, developing its capacity can create greater freedom in performance.

At the StretchiFlex, we believe that capacity creates acting freedom. Not because every actor needs to be an athlete, but because physical limitations shouldn't unnecessarily restrict creative possibilities.

Why Is Physical Training Important for Actors?

Acting is a physical profession, even when a performance appears relatively still.

Consider how much an actor communicates without speaking. A shift in posture, a change in breathing, the way someone enters a room or holds tension in their shoulders - all of these small moments inform an audience something about a character before a single line is delivered.

Our bodies are constantly contributing to the story !!

But beyond physical expression, acting can also demand considerable stamina, coordination and resilience (iykyk) !!

A performer might spend hours standing on set, repeat a physically demanding scene across multiple takes, work through complex choreography or maintain concentration during a long rehearsal day.

Physical training helps prepare the body for these demands.

Rather than training exclusively for appearance, actors can benefit from developing the physical qualities that support their work: strength, cardiovascular endurance, mobility, balance and coordination.

The goal isn't to create one particular type of body. It's to develop a body that can respond to the creative demands placed upon it.

1. Strength Training Helps Actors Meet the Physical Demands of Performance

Strength training for actors isn't necessarily about building large muscles or achieving a particular physique, it's about developing the ability to perform physical tasks with greater control and confidence.

Consider an actor preparing for a role involving running, lifting, fighting, dancing or repeated movements. Developing appropriate strength can help them approach the physical demands of that role more effectively.

But strength is equally valuable for performers whose roles aren't particularly athletic.

Maintaining posture during long rehearsals, moving repeatedly between standing and sitting, and managing the physical demands of extended working days all require muscular capacity.

A balanced strength training programme might include squats, lunges, rows, presses and exercises that develop trunk stability: all foundational movements that can help actors build strength across the body without requiring an unnecessarily complicated routine.

TLDR: Strength training isn't simply about how an actor looks. It's about developing what their body can comfortably and confidently do.

2. Cardiovascular Fitness Supports Stamina and Performance Endurance

Have you ever considered how physically demanding a day on set can be? (No wonder you’re tired, right? It’s not just because it was a long day for you!)

It's no surprise that long hours on set, repeated takes, emotionally intense scenes and physical choreography can all place demands on an actor's energy.

Cardiovascular training develops the body's ability to sustain physical activity and recover from exertion.

For an actor, this might mean feeling better prepared for a demanding rehearsal schedule, recovering between physically active takes or maintaining energy during an extended performance.

Cardiovascular conditioning can also be particularly relevant to performers who combine acting with singing, dancing or musical theatre.

Activities such as brisk walking, cycling, swimming, jogging or appropriately programmed interval training can help develop aerobic fitness.

The most effective choice depends on the your current fitness, experience and the demands of your work.

TLDR: Building stamina helps actors prepare for demanding working conditions, rather than relying on energy and endurance they haven't had the opportunity to develop.

3. Mobility and Coordination Create More Physical Choices

One of the most interesting aspects of acting is how differently two performers can interpret the same character.

A character's physicality might be confident and expansive, restrained and guarded, awkward and unpredictable, or incredibly precise.

Developing mobility, balance and coordination can give actors a broader range of physical possibilities to explore.

Mobility refers to the ability to move a joint through its available range with control. Coordination involves organising movements effectively, while balance helps us maintain stability as we move.

Together, these qualities can support physical expression and movement confidence.

For example, an actor with good balance and body awareness may find it easier to explore unfamiliar movement patterns, respond to blocking adjustments or learn choreographed sequences.

Exercises such as controlled lunges, single-leg balances, thoracic rotations and dynamic mobility drills can help develop these qualities.

This doesn't mean every actor needs exceptional flexibility.

In fact, flexibility without adequate control isn't necessarily useful for performance.

The aim is to develop movement options that are appropriate for the individual and the work they want to pursue.

TLDR: The more movement choices an actor can access and control, the more possibilities they may have when exploring a character's physical world.

4. Physical Preparation Can Support Confidence Under Pressure

Acting often almost always involves stepping into unfamiliar situations.

An actor might be asked to perform a movement they've never attempted, work with an unfamiliar prop, learn choreography quickly or adjust their physical performance in response to a director's instructions.

These situations can become more challenging when the performer is also concerned about their physical ability to complete the task.

And this applies to even the smallest details of a performance.

For example, I spent several months working as a body double on a television series, and on one particular day, I was given the seemingly simple task of turning on a record player and gently lowering the needle onto a record.

Easy enough, right?

Well, apparently not.

A very well-known international director took one look at my attempt, laughed (kindly!) and told me, “The world would know that hand had never done that before.”

Fair enough. He wasn't wrong.

He patiently walked me through how to lower the needle onto the record as though I'd done it a thousand times. But here's the interesting part: it wasn't really the movement itself that I needed help with. It was controlling my body's response to the pressure.

Because when you're performing a tiny, precise movement in an extreme close-up, with a room full of people (including some rather famous faces) watching your every move, suddenly keeping your hands steady becomes a skill of its own.

And that's where physical training comes in. Developing body awareness, coordination and the ability to regulate your physical response under pressure can make a real difference, even when the task seems ridiculously simple.

Sometimes, the physical demands of acting involve running, jumping or performing elaborate choreography. Other times, they're as simple as lowering a needle onto a record player with the same ease and familiarity your character would have in the comfort of their own home, rather than under the pressure of a film set full of watching eyes.

Regular physical training provides opportunities to practise learning movements, developing coordination, managing effort and gradually approaching new physical challenges.

Over time, this experience may help build confidence in the body's capabilities.

Of course, physical fitness doesn't eliminate performance anxiety, and exercise isn't a replacement for acting training or appropriate mental health support.

But becoming more familiar with what your body can do may reduce some of the uncertainty surrounding physically demanding (or just plain physical) performance tasks.

There is SO MUCH value in the training process itself. Progressing through a challenging exercise, learning a new skill or improving balance requires patience, consistency and a willingness to practise something before becoming proficient.

These are qualities that can translate meaningfully into an actor's approach to developing their craft.

5. Recovery Is Part of an Actor's Training

When discussing fitness for actors, it's easy to focus entirely on what performers should be doing more of: More strength training, more cardiovascular exercise, more mobility: but recovery is equally important.

Actors may experience irregular schedules, long working hours, periods of high physical demand and stretches of uncertainty between jobs.

Adding excessive exercise to an already stressful/demanding schedule isn't necessarily productive.

Recovery helps the body adapt to training and manage accumulated fatigue.

Depending on individual needs, this might involve adequate sleep, appropriate nutrition, rest days, gentle movement or lower-intensity exercise.

A short stretching session or an easy walk can be a useful way to introduce movement without adding another demanding workout.

The goal is to find a sustainable balance between preparation and recovery.

TLDR: Training should support an actor's creative career, not leave them too exhausted to participate in it.

What Does a Good Workout Programme for Actors Look Like?

An effective fitness programme for actors doesn't need to involve hours in the gym every day.

For many performers, a practical starting point is two or three strength training sessions per week, alongside cardiovascular activity, mobility work and, of course, appropriate recovery.

And to make things even easier, I've created a FREE three-day training programme designed specifically for actors! A little gift from me to you, for making it this far into the article - and maybe also to celebrate the fact that we're starting blogs again after one year away HAHA OOPS. Time flies. :)

Download your FREE 3-Day Actor Training Programme HERE !!

Each session takes approximately 30 minutes and is designed to help you develop strength, coordination, balance and physical capacity without taking over your entire week.

Of course, the appropriate intensity, exercise selection and training volume will depend on your fitness level, experience, recovery needs and performance commitments, so adapt the programme (specifically, the weight used) to suit you.

And remember, if you're preparing for a particularly physically demanding role, you may also benefit from specialist training in areas such as stage combat, dance, stunt preparation or movement coaching.

General fitness provides a fantastic foundation, but it doesn't replace these specialised disciplines.

Looking for something a little more personalised? I also offer a limited number of in-person personal training sessions in St Kilda, Melbourne, for performers who would benefit from more individualised guidance and support.

Do Actors Need to Be Fit to Be Successful?

No. There is no universal fitness standard that determines whether someone can become a successful actor, and quite frankly the ‘beauty standard’ needs to change.

Acting is a creative discipline that requires imagination, listening, emotional availability, technical understanding and the ability to communicate a story truthfully.

Physical fitness cannot replace those skills.

Nor should an actor feel that their body needs to look a particular way to deserve opportunities within the industry.

The purpose of physical training is not to suggest that performers are inadequate without it, but instead, it offers an additional avenue for professional development.

Just as an actor might undertake dialect coaching, singing lessons, movement classes or screen acting workshops, physical conditioning can become another tool in your preparation.

The question isn't whether every actor should achieve the same level of fitness, it's whether developing greater physical capacity could help your performance, and in turn help you pursue the kind of work you want to do.

Capacity Creates Acting Freedom

At the StretchiFlex, our approach to training begins with a simple idea:

Capacity creates acting freedom.

We don't train simply to change how a performer looks; we train to expand the physical possibilities available to them: to increase your capacity and ability to do more of what you love.

To develop the stamina to approach demanding work, the strength to support physical tasks, the coordination to explore unfamiliar movement and the confidence to keep learning.

You body as an actor is not separate from your creative instrument: it's part of how you tell stories.

And while physical preparation will never replace the craft of acting, it can support you: the performer behind the performance.

Because ultimately, the goal isn't to become a particular shape, size or type of actor, it's to develop the capacity to do more of what you love :)
