I Used The pliability Mobility App For One Month – Here’s What Happened

Could daily mobility and recovery routines transform our writer Sam Rider’s rigid frame into a well-oiled machine?

In an effort to improve his mobility, Sam Rider dusted off his exercise mat and put mobility app pliability to the test. For four weeks, he did one of pliability’s stretching routines every single day. Here are the results…

I have a theory that stubborn inflexibility is holding me back. I know this thanks to a Team GB Olympic lifting coach whom I trained with back in my mid-20s. Twice a week he subjected me to a barrage of mobility drills before I was allowed anywhere near the bar, and as a result, my clean and jerk and snatch went through the roof. 

A decade later, however, stretching barely registers on my weekly schedule – bar straining to pick my newborn son’s toys off the floor. That’s partly because it can be agony, a bit like flossing for the first time in weeks. You know if it became routine, your gums wouldn’t sting so much. But, frankly, it’s tedious. 

It’s also time consuming and, despite the army of advocates online telling you otherwise, nowhere near as sexy as a sweaty metcon class. Mobility training, in other words, needs a rebrand. Enter: pliability. Born out of CrossFit, the “human movement” specialists (formerly known as RomWod) are on a mission to extend the benefits the functional fitness community now enjoys to sports and fitness disciplines beyond the box. 

“Our ethos is finding freedom through movement,” says Director of Performance, Cody Mooney. They’re not just about helping you cross the proverbial finish line, they want you to enjoy every step along the way. 

And a recent systematic review on the effects of static stretching suggests if you follow their lead you could realise plateau-busting gains in strength and power too – results that are especially pronounced in older and more sedentary individuals. 

So, with that in mind, I decided to put this theory to the test and see what a month of daily stretching and mobility training could do for my ageing, increasingly stationary, physique.

The features – how pliability works

pliability functions, first and foremost, as a vast library of mobility routines, dynamic warm-ups, bodyweight exercises and cooldowns categorised by body parts (eg. lower back and hips), exercises (eg. deadlifts and pull-ups) and sports (eg. running and golf). But one of the cleverest features is its Mobility Test, which is where I’m recommended to start.

This involves performing a series of overhead squats (with arms held aloft rather than holding a bar) in front of my mobile phone’s camera, both front on and to each side, while the app maps out my ROM. With this data it provides a score for dorsiflexion, knee width, scapula rotation and more to calculate an overall mark out of 100. 

My magic number is 85 (76 for overhead, 93 for squat), with three mobility issues detected: back arch, low arms and, rather inquisitively, head tilt. A respectable score, I think, but plenty of room for improvement. Armed with this score to beat, I’m next prompted to input more personal details and goals, then kicked through to the main dashboard. 

Here I’m presented with a choice. Dive into one of the week’s scheduled routines, which work like CrossFit’s WOD (workout of the day), or start a “new path” based on my preferences. 

Initially this was limited to just running and golf, but pliability has since added a Workforce hub for desk bound release and a Pregnancy + Postpartum hub developed with specialist coaches from The MINT Prjct and shot with six-time CrossFit Games champ Tia-Clair Toomey-Orr.

To coincide with the 2024 CrossFit Open, pliability has also released routines tailored to whatever devilish workout combination Dave Castro could conjure up, which I found an especially welcome addition towards the end of my review. But back in January, the obvious choice was the seven-day Welcome Series, which is where I began. 

The trial – week by week

For my first routine, I clear some space in my son’s nursery – illustrating that you can get these classes done literally anywhere – prop my mobile up on the floor and hit play. Two models in a dimly lit CrossFit box proceed to demonstrate five lower body stretches, while a narrator with deep, dulcet tones from the Pacific west coast, provides instruction. 

The class culminates with a three-minute frog stretch hold, a move that demands 270˚ hip articulation even a toddler would struggle with. 

Counting the seconds down is excruciating. Usually I would have tapped out after half a minute, and that’s the point. After initial resistance, my pelvis gradually surrenders to the passive stretch and I can feel my muscles relax, even if only fractionally. The narrator signs off with a pep talk: “Being persistent – and being consistent – is the key,” he purrs. 

The rest of the Welcome Series follows a similar pattern. Each routine involves long-held passive stretches, postures yogis would recognise like the downward dog (hamstrings) and forward fold (lower back), and moves popularised by the functional fitness community, like the twisted cross (pecs), seal and sphinx (abs). 

Spending 2+ minutes in each of these poses feels like it’s helping melt away tightness my body has been hanging onto, and I feel better equipped to handle twists and turns on the five-a-side pitch, having spent time mobilising my body earlier in the day. 

By day five the narrator starts introducing two additional elements: eight second nasal breathing and a “rebound” pose at the end of each routine, whereby you’re encouraged to lay flat on your front with eyes closed to let the effects of the class sink in. 

“At pliability we believe stretching is essential to an athlete’s routine,” the narrator says, introducing the last day of the series. “It helps to improve flexibility, range of motion and muscle performance. Stretching can also help reduce the risk of injuries, improve circulation and promote relaxation.”

By this point the intensity has really cranked up, kicking off with three back-to-back moves honing in on my – and likely most people’s – major tight spot: the hamstrings. 

A half-front split is a brutal way to start a Monday morning. It involves an asymmetrical hamstring, calf and lower back stretch I can barely comprehend, let alone mimic. This torture is followed by a single-leg forward fold, then rounded off with the “fragon” pose, which also feels like it has a personal vendetta against my hips and groin. 

Altogether it’s a humbling 20 minutes that reminds me effective stretching can be as physically and mentally testing as a hypertrophy superset or fat-burning workout.

The test – before and after

With the Welcome Series complete, I use the rest of the month to dovetail the Desk Job Hero path, designed to combat sedentary strains and the pitfalls of prolonged sitting, with one named Runner Hip Health. Each involves just two sessions per week, representing a far more manageable commitment that I can build around my regular workouts and working day. 

I also dip into the app to find a hamstring-specific routine after a late night football match, and again for a lower back-focused cooldown after a publishing set of burpees, cleans and failed muscle-ups, proving its usefulness as an exercise directory to address specific ailments. 

Then, after a month spent accumulating more minutes of mobility training than I have in the previous 35 years, it’s time to revisit the test I performed on day one. Could daily mobility routines have transformed my previously rigid frame into that of a well-oiled machine, capable of bending to my will while harnessing muscles I never knew existed?

Alas, 30 classes and 450 minutes later, my score has dipped by four points, from a PB of 85 to career low of 81. The three issues initially identified (back arch, low arms, head tilt) still persist, and while my shoulder mobility has picked up, my back/core and left hip are now playing up. 

And, because I’ve had to cut down on strength training to squeeze in my daily stretching routine, I’ve also felt a little undercooked when I have got back in the gym. My overhead press has dropped off a cliff and the impending 24.1 workout is sending shivers down my spine. 

The verdict – is pliability worth it?

In fairness, though, the masterminds behind pliability will tell you one month isn’t long enough to enjoy ingrained, long-term gains. Former CrossFit Games athlete-turned-co-founder Mooney says that in the first week you should notice reduced stiffness, improved sleep and enhanced mental calm.

Greater range of motion, increased flexibility, reduced joint discomfort and faster recovery comes after 60 days; enhanced training capacity, improved athletic performance and reduced incidence of injury after six months. 

When I put this to the owner of an esteemed London CrossFit box, one that streams pliability routines in its warm-up/cool down area for members to dip in and out of, he’s a little more sceptical. “How much mobility do you actually need?” he asks. “The answer is ‘enough’. Enough to perform an exercise efficiently, effectively and safely.”

At this particular box, rather than prescribing standalone mobility classes, workouts start with the time-honoured RAMP protocol (first popularised by Dr Ian Jeffreys and Mark Verstegen in the mid 2000s).  

Standing for Raise, Activate, Mobilise and Potentiate, this involves raising the body’s core temperature and boosting blood flow, activating muscles to promote stability and balance, mobilising areas of the body as required for the workout in question, and potentiating – or priming – the central nervous system for action.  

For sedentary individuals, a few minutes of mobility work every day will certainly “shift the needle” he said, “but if you’re already mobilising your body regularly through exercise, cycling to work or playing football, that’s usually enough”. Most people simply don’t have the time to commit an extra 15-20 minutes per day to mobility training. 

And yet, this coach admitted, were they to carve out this time to relax – perhaps while mobilising their bodies with a couple of choice stretches – the mental benefits of slowing down, breathing calmly and being present in the moment could be profound. For me, that’s where pliability excels. It’s as much therapy for the mind as it is for your joints and ligaments. 

Every four-minute hold and eight-second breath forces me to stop, to quiet my whirring mind and listen to my body. And now, one month later, I’m armed with a library of CrossFit-approved stretches and mobility drills that I can dip into on-demand. 

It might not be the cure-all solution I was hoping for, but it has become a welcome addition to my training toolkit. A reminder to occasionally hit pause, to decompress and surrender to the tension-melting, stress-busting benefits of daily movement.
