Best exercises, gyms, classes & benefits

‘Functional fitness’ is a term that throws even the most seasoned fitness pros (… you rang?). Otherwise known as functional training, it’s a buzzphrase that’s dallied around in gym circles or class descriptions without most people being 100% clear what it actually means. Surely all training is functional? Kind of, but it’s the real-life functionality we’re talking about that’s often left out of other workout routines, increasing risk of injury.

We spoke to Emily Outterside, Senior Coach at F45 Oxford Circus to get with the programme.

What is functional training?

‘Functional training (a.k.a. functional fitness) is a form of exercise that conditions our body through strength, agility and stability movements,’ Emily explains.

Functional fitness typically uses bodyweight or free weights, rather than machines, as functional training exercises involve using multiple joints and moving in multiple planes — meaning forwards and backwards, from side to side and rotationally.

‘A compound exercise, like a squat, is a typical example of a functional training exercise. It uses a variety of muscles and joints in the knees, hips and legs, as well as having the benefit of strengthening your tendons, bones and ligaments around the leg muscle,’ she says.

So, compound exercises, which train multiple muscle groups at the same time = good for helping your body function as a whole, not just in the gym but for daily movements.

‘Isolation exercises, compared to functional training exercises, focus on a specific muscle group, with little input from other muscles. For example, a bicep curl only uses the biceps to lift the weight and just the elbow joint for movement. Though this is good way to gain muscle mass, it doesn’t translate into benefiting us on a holistic all round level,’ Emily tells us.

So, isolation exercises = less effective at training your body for real-life activities and range of motion. Which makes sense, right? Think of something heavy you’d pick up in the same way you do a bicep curl. We’ll wait.

What are functional fitness benefits?

Rather than focusing on maximum #gains and bulking, Emily says you’ll reap the following rewards from functional training:

  • Build mobility
  • Build power
  • Build speed
  • Strengthen muscles
  • Coordination

‘In the real world we have no machines to support our body, so working on our balance while coordinating the body through these movements is hugely beneficial to day to day life, reducing our risk of injury as a great benefit,’ Emily explains.

Mobility, power, speed, strength, balance AND coordination — where do we sign up? (Scroll down if you’re already sold and you want to find functional fitness gyms or classes.)

Should everyone do functional fitness?

Absolutely everyone should be doing some form of functional training and it’s suited for all ages and abilities, which is part of its beauty. Any movement can be altered for ability level via tempo, reps or added resistance,’ Emily says.

‘It would be particularly good for anyone sat working at a desk for prolonged hours of the day as most functional training works the muscles that help keep your posture strong. Functional training also improves mobility through the hips and shoulders, which are the typical areas of discomfort for those sat at desks.’

Not just for WFH-ers, from a strength training perspective, functional training is far more efficient as it trains the muscles to work together — which is more a reflection of what happens IRL.

Functional training is also useful for older adults as, by mimicking everyday movements, it addresses uneven muscle balance and asymmetries that are more likely to lead to injury.

What does a typical functional fitness workout consist of?

‘A typical functional training workout will vary depending on the goal, but typically it’s a mixture of exercise that will improve your cardiovascular system as well as your strength,’ Emily tells us. These can include:

  • Plyometric exercises like jump squats and burpees
  • Unilateral exercises like lunges or single leg deadlifts
  • Compound exercises like deadlifts, shoulder presses and squats

A key advantage of functional training is that you don’t need any equipment to have a good, effective workout.

Here are functional training exercises you can do at home or in the gym, recommended by Emily:

Best functional fitness exercises

1.Walking lunge

Why? ‘This works our body unilaterally which is great for fixing any imbalances in the body.’

2. Press ups

Image no longer available

Why? ‘These are great for our upper body strength, as well as core stability and a great exercise for scaling up or down depending on ability.’

3. Squats with overhead reach

Image no longer available

Why? ‘These are mainly targeting our quads, glutes and hamstrings. They are a great exercise for building strength.’

4. Plank

Image no longer available

Why? ‘With this exercise you are strengthening your core, arms, shoulders and legs; it improves your posture and stability, and overall strength.’

5. Deadlift

Image no longer available

Why? ‘Deadlifts are super effective at increasing functional strength as they activate your largest lower body muscles, and also train you for the functional activity of safely lifting objects off of the floor in day-to-day life.’
