In the ever-evolving landscape of fitness trends and buzzwords, few terms have become as overused—and misunderstood—as “functional training.” Originally intended to describe movement patterns that carry over to real-life physical tasks, the phrase is now often applied to everything from kettlebell circuits to balancing on unstable surfaces while doing bicep curls. But what does functional training actually mean? And perhaps more importantly, is it a term that still holds any practical value, or has it become a marketing gimmick with little substance?

 

The Origins of Functional Training

The term “functional training” originated in rehabilitation settings, where physical therapists aimed to restore patients’ ability to perform daily activities. The idea was simple: exercises should improve the movements people need to function independently—whether that meant getting up from a chair, climbing stairs, or lifting groceries. From there, the concept migrated into the broader fitness world, particularly in the strength and conditioning field.

In athletic settings, functional training took on another layer of meaning. Coaches began to design programs that mimicked the movement patterns, speeds, and forces encountered in sport. Exercises that trained multiple joints and muscle groups working together in coordinated ways were considered more “functional” than isolated, single-joint movements like leg extensions or bicep curls.

This progression made sense: movement in both life and sport is multi-planar, integrated, and often performed under load or fatigue. Training in ways that replicate those conditions, the thinking goes, better prepares individuals for the demands they face outside the gym.

 

The Problem with the Term Today

Fast forward to today, and the term “functional training” has become so diluted that it’s nearly meaningless. It’s used by influencers to label any non-traditional gym exercise. It’s slapped onto bootcamps and group fitness classes that may or may not be rooted in sound principles. And it’s often conflated with trends like balance training, suspension training, or using unconventional tools like battle ropes and sandbags.

Here’s the core issue: functional for whom, and for what purpose?

A powerlifter training to deadlift 600 pounds has a very different definition of “functional” than a 70-year-old trying to maintain independence. A baseball pitcher has functional needs that differ drastically from a weekend warrior recovering from knee surgery. Without context, the term becomes vague, subjective, and often misleading.

 

Principles Over Labels

Instead of asking whether an exercise or training style is “functional,” it’s more helpful to ask whether it follows good training principles:

1. Specificity: Does the training target the movement patterns, energy systems, and physical qualities needed for the individual’s goal?
2. Transferability: Will the adaptations from this exercise carry over to real-world tasks, sport performance, or injury resilience?
3. Progressive Overload: Is the training providing a stimulus that challenges the body and promotes adaptation over time?
4. Movement Quality: Does the training reinforce proper mechanics, postural control, and motor coordination?
5. Individualization: Is the training appropriate for the person’s current abilities, limitations, and goals?
   
   

If a program hits these notes, then it doesn’t matter whether it’s labeled as “functional”—it is effective.

 

Common Misconceptions About Functional Training

Let’s address a few of the most common myths surrounding functional training:

●       Myth #1: Machines aren’t functional.
 Machines can be useful tools, particularly in early rehab or hypertrophy-focused phases. They allow for targeted loading without requiring complex stability demands. Whether they’re “functional” depends on how they’re used within a program.

●       Myth #2: More instability equals more function.
 While training on wobble boards or BOSU balls can have applications for ankle rehab or proprioception, constantly destabilizing exercises isn’t always more functional. Most real-life tasks (and sports) occur on stable ground. Loading basic movements like squats, hinges, pushes, and pulls on solid surfaces typically provides better strength and neuromuscular adaptations.

●       Myth #3: Functional training avoids heavy weights.
 On the contrary, functional training often involves lifting heavy loads—provided that doing so supports the individual’s goals. Farmers need grip strength, athletes need power, and older adults need the ability to get up off the floor or carry groceries. Load is not the enemy; inappropriate application is.

 

So, Is the Term Worth Keeping?

“Functional training” still holds value if it is properly defined and applied. It can serve as a useful shorthand to remind coaches and clients that training should have a purpose beyond aesthetics. It can highlight the importance of integrated movement patterns, core control, joint stability, and task specificity. But without context, the term becomes a hollow buzzword.

A more meaningful approach is to zoom in on function for the individual. A mother of two with back pain may benefit from different “functional” patterns than a competitive CrossFitter. Rather than trying to fit everyone into a pre-defined category of functional training, the smarter move is to assess their needs and build programming around those realities.

 

Conclusion

“Functional training” started with noble intentions—helping people move better, live better, and perform better. But as the term has been co-opted by marketers and misapplied in practice, its meaning has grown increasingly unclear. Instead of chasing labels, coaches and individuals should focus on training that improves meaningful function, whatever that may be for them.

Ultimately, the question isn’t is this exercise functional? but rather functional for what? And for whom? That shift in thinking leads to better outcomes, fewer gimmicks, and a training program that actually serves a purpose.
