From boutiques to mainstream gyms, ‘functional training’ has become the latest buzz-word to describe many trending workouts. But what does it actually mean? And is there any substance behind the hype? We caught up with the experts to find out…

What is functional training?

Functional training incorporates multi-joint movement patterns to keep us fit and strong for everyday life. “It uses exercises that replicate total body movements and patterns seen in sports and daily activities in general,” says Rob Lee, Physiotherapist and Les Mills Technical Consultant. “Functional training provides strength and mobility that is transferrable to other tasks. Essentially, it’s training that doesn’t work muscles or movements in total isolation.”

Why should you include it in your fitness regime?

“Functional training enhances your ability to perform other activities outside the gym, whether that’s simply being able to get up off the couch or improve your golf swing!” says US-based Trainer Kenta Seki. “When you train the right muscles correctly and frequently, you also decrease your risk of getting injured when undertaking everyday activities.”

Chris Wright, Head of Strength and Conditioning at Loughborough University in the UK, agrees: “Think about a mother who needs to pick her child up off the floor. That task will require movement of the ankle, knee and hip – a squat-type pattern – to lift the load. You can replicate this movement pattern on the gym floor with a deadlift. We can see that strengthening the muscles around those same joints is going to minimize her risk of injury when it comes to picking up her child.”

It’s not all flipping tyres, handstands and battle ropes…

Contrary to what you might see on the 'Gram, you don’t have to be pushing a heavy sled to be performing functional movements. “The exercises are not all extremely challenging, requiring an elite skill level,” says Lee. “It’s not all dangerous. Good functional exercises use total body movements that replicate relevant movement patterns from your life or sports. The squat itself is a brilliant functional exercise. Functional exercises can be easily adapted to suit different fitness levels."

You can also add elements of functional training into your existing exercise plan. "Deciding to include functional exercises in your training doesn’t mean you need to ditch everything you're currently doing," explains Chris Gagliardi, ACE (American Council on Exercise) Scientific Education Content Manager. "You might be able to incorporate functional training exercises into your warm-up or cool-down, or even into the conditioning phase of the workout."

Is it for everyone?

Within reason, yes. “Like all training methods, the complexity, intensity, frequency, and load help determine its suitability, “says Lee. "If these things are not matched to an individual’s skill and fitness level, it may cause issues. But pitched at a safe and effective level, yes – functional training can be suitable for everyone.”

“The biggest benefit of functional training is that it is appropriate for all fitness levels and can be done in a variety of settings, both with and without exercise equipment,” says Gagliardi. “This type of training establishes postural stability and makes sure that each joint in the kinetic chain is stable or mobile at appropriate times. It’s also not just for beginners. Even elite athletes can benefit from functional training for improvements in postural stability and kinetic chain mobility, helping them move more efficiently.”

Intensity isn’t the most important factor

Despite the rising trend of high-intensity functional workouts, this type of training doesn’t have to leave you sobbing in a pool of your own sweat… “Functional training is often associated with an extremely high intensity and taking people to breaking point but it doesn’t have to be done at our maximal efforts,” says Lee. “Understanding and learning good functional training exercises is an excellent way to create balanced strength through multiple ranges and planes of movement.

“The benefits can also be seen when training at low and moderate intensities,” continues Lee. “That's when we master these movements. Sure, there is a time to push the intensity and improve your fitness capacity, and we can achieve this with functional exercises, but this should not be done at the expense of losing good movement control.”

If your knees are caving in, it's time to drop the weight

“The biggest thing is to do the basics really well,” says Wright. “It’s a great idea to film yourself performing the exercises so you can check your technique. You also need to know what ‘good’ looks like, so it can be helpful to work with a personal trainer who can check your form and explain why certain movements are included in your program."

“Technique doesn’t go out the window just because you're doing functional training!” adds Lee. “I frequently see good technique being sacrificed to do the exercise just for the sake of it. It's much better to try a simpler version of the exercise – whether that's dropping the load or the complexity – to ensure you're moving efficiently and with good form. That's probably the most functional thing you can do!”

“If you’re going to invest your time in functional training, then the biggest thing to consider is – what outcome are you trying to achieve?” continues Wright. “I wouldn’t recommend doing it just because you’ve seen somebody doing it on social media. Whether you’re new to exercise or a performance athlete, you need to understand why you’re investing your time and energy in training that way because, depending on your goals, functional training might not be the most efficient way to achieve them. And when it comes to high-intensity functional training, you probably don’t need to be doing it 5-6 times a week. You need to allow time for recovery between sessions, so your body can adapt and get the results.”

Technology for optimal performance

Whilst wearable sensors can give us data on our heart-rate, calorie burn, steps etc., how do we know if, for example, we're moving at the optimal speed in our deadlift? Technology could be the answer, says Wright. “In the sports performance world, we already use technology that tracks the velocity in movements. Say I want to get stronger in my back squat: I might be aiming to lift 85 kg every day. If technology tells me that I’m losing speed, I might then drop my load down to 78 kg to still achieve the strength gains.”

“I would like to see technology that focuses on the feedback of movement technique and loading become more prominent,” adds Lee. “This could ensure exercises are being performed efficiently and effectively for specific individuals, maximizing their effects in certain sports and activities.”

The future looks functional

The trend towards functional training looks set to continue, with many workouts (including BODYPUMP and LES MILLS CORE) already incorporating these types of movements in their programming. “I think many methods of training will begin to incorporate exercises that are considered functional,” predicts Seki. “Even some bodybuilders I know are starting to include some compound functional exercises into their routines! I’m sure we’ll also continue to see the emergence of new training equipment and brands that focus on functional training.”

“I expect to see it more universally applied across exercise in general,” agrees Lee. “I think a lot of people are doing functional training without really knowing it! We will get better at understanding its effects on and how it relates to not only performance but other health outcomes.”

“Right now, functional training is where it’s at for me,” says Glen Ostergaard, Program Director for BODYPUMP. “I’ve been adding functional exercises into BODYPUMP like pushups mixed in with the bench press, or mountain climbers in with tricep extensions. Throwing full body exercises into the mix means that, when you get back onto the bench to do a more isolated exercise, it’s a whole lot harder and you get more out of it as a result. I’ve been very deliberate in the way I’ve introduced the functional moves and it’s definitely where BODYPUMP is right now. I can see us staying in this phase for a while.”

The most effective functional exercises

With many exercises falling under the umbrella of ‘functional’, which will give you the most bang for your (training) buck?

If you're just getting started, Gagliardi suggests you try exercises which allow you to achieve core stability first before progressing to more advanced options. Good options include a glute bridge, bear crawl, spider walks, inchworm and stability ball walk out.

For those who are a little more confident, Lee advises: “Choose exercises that incorporate large movements while challenging your trunk stability and incorporate more than one movement pattern”.

Here are some of the functional training favorites:

Squat to Overhead Press Move the weight from below head height to above the head using the fundamental squat pattern.

Deadlift to Single Arm Dumbbell Row Combining the hip hinge pattern of bending and lifting with an offset weight pull.

Offset Kettlebell Lunge Mimics a common movement pattern of a lunge/run stance, total body challenge; you can mix up the kettlebell position.

Offset Weight Walk (Like a heavy suitcase) Or Farmers carry with a heavy weight in each hand.

Medicine Ball Throw Lifting the ball off the floor and pressing to replicate moving objects of all kinds at all speeds.

Box Step-ups and Box Jumps Full body step pattern that adds an explosive and force absorption element.

Sled Pulling and Pushing Pushing and pulling objects using your entire body to create momentum challenges structural integrity and increases your total body capacity.

Burpees (You knew they were coming…) Nothing like getting up and down off the floor for total mobility and strength!
