If You're Not Sure What CrossFit Actually Is, You're in Good Company
Maybe you've seen people lifting barbells, doing pull-ups, running, rowing or jumping rope.
Maybe you've heard stories about intense workouts and wondered whether CrossFit is really for someone like you.
Or perhaps you're simply looking for a way to get stronger, fitter and healthier without spending hours in a gym.
So, what exactly is CrossFit?
CrossFit Is Training for Being Fit in Lots of Different Ways
At its simplest, CrossFit is a way of developing broad, general fitness.
That means we don't train just one quality.
We work on strength, endurance, stamina, flexibility, power, speed, coordination, agility, balance and accuracy.
These are the 10 general physical skills that form the foundation of the CrossFit definition of fitness.
Think about what that means outside the gym.
Being fit isn't only about how fast you can run.
It's also about being strong enough to pick something up, having the stamina to keep going, moving well, coordinating your body and having the balance and control to handle whatever life puts in front of you.
That's the idea behind CrossFit.
You Don't Have to Be "Fit" Before You Start
This is one of the biggest misconceptions about CrossFit.
You might picture someone walking into a CrossFit gym already strong, athletic and capable of doing pull-ups.
That's one version of CrossFit. It isn't the only version.
CrossFit is designed to be scalable. The same basic training approach can be adjusted for someone who is highly trained and someone who is starting from a much lower level of fitness.
The difference between an elite athlete and an older or deconditioned person is a difference in degree, not kind. The goal shifts from functional dominance to functional competence, while the underlying training principles stay the same.
In practical terms, your workout might involve a lighter weight, fewer repetitions, a different movement or a shorter distance.
Your coach's job is to help you find the version of the workout that challenges you appropriately.
Every workout starts where you are.
Come and see how coaching and scaling make CrossFit work for any starting point.

Strength training is an important part of CrossFit.
You'll see movements such as squats, deadlifts, presses, cleans and other lifts. Olympic weightlifting movements such as the clean and jerk and snatch are also part of the broader CrossFit approach.
Weightlifting is a way to develop strength, speed, power, flexibility, coordination, agility, accuracy and balance all at once.
But that's only one piece.
CrossFit also incorporates gymnastics and bodyweight movements such as:
- Pull-ups
- Push-ups
- Dips
- Other exercises that develop body control
You'll also encounter running, rowing, cycling, jumping, throwing, kettlebells and other forms of conditioning.
The goal is to develop a wide range of physical abilities.
Why Are the Workouts Always Changing?
CrossFit puts a lot of emphasis on constantly varied training.
The reason is simple.
Your body adapts to the things you repeatedly ask it to do.
If you only train one movement, one distance, one repetition range or one type of conditioning, you'll become very good at that particular thing — and not much else.
CrossFit deliberately uses a broad range of movements, loads, repetitions, time domains and combinations.
The training stimulus is deliberately broadened so the body keeps adapting to different demands.
That might mean today's workout looks completely different from tomorrow's.
One day you might focus on building strength.
Another day could involve a short conditioning workout.
Another could combine strength, gymnastics and conditioning.
The variety keeps training challenging and gives you opportunities to develop different aspects of fitness.
What About Cardio?
CrossFit doesn't treat "cardio" and strength as completely separate worlds.
The CrossFit fitness model recognises three major energy systems that contribute to human movement: the phosphagen, glycolytic and oxidative pathways.
Different activities place different demands on these systems, depending largely on their intensity and duration.
That's why CrossFit might include a short sprint one day and a longer rowing or running effort another day.
You're training your ability to produce energy for different kinds of work.
What Does a CrossFit Class Actually Look Like?
Every gym structures its classes a little differently, but a typical session may include:
- A warm-up — preparing your body for the movements and workout ahead
- Skill or strength work — learning or practising a movement, or working through sets designed to build strength
- The workout — the conditioning portion of the session, which might combine several movements and challenge you through repetitions, time, distance or load
- Coaching and scaling — your coach helping you choose appropriate movements, weights and intensity for your current ability
The important thing is that you don't have to perform the exact same version as the person next to you.
You are working toward becoming a better version of yourself.
What Makes CrossFit Different From Simply Working Out?
A big part of the answer is breadth.
The goal isn't to become exceptional at one narrow fitness quality.
It's to become capable across many different physical demands.
CrossFit's specialty is "not specialising." The overall aim is broad fitness that prepares you for a wide variety of physical challenges.
For someone in their 30s, 40s, 50s or beyond, that idea can be particularly practical.
You may want to lose some weight. You may want to get stronger. You may want more energy.
You may want to feel confident carrying your shopping, playing with your children or grandchildren, going on holiday, climbing stairs or staying active as you get older.
Those aren't separate goals. They're all expressions of being physically capable.
So, Is CrossFit for You?
You don't need to be an athlete.
You don't need to know how to do a snatch.
You don't need to be able to run five miles.
You don't need to walk through the door already feeling confident in a gym.
You simply need to be willing to start where you are and work from there.
A good CrossFit programme meets you at your current ability and gives you a path to improve.
