If your feed suddenly looks like it’s been sprinkled with Snapchat dog filters and the faint scent of pre-workout from a decade ago, you’re not imagining it. The 2016 throwback craze has become the latest fitness trend taking over social media, with Instagram and TikTok users posting side-by-sides of how life (and lung capacity) has changed over the past ten years.
And, naturally, gym culture has latched on like a sweaty gym towel to a vinyl bench.
Fitness influencers and everyday gym-goers have joined the nostalgia parade, comparing today’s routines to the glory days of 2016 — when “leg day” was optional but “cardio punishment” was practically a religion.
TikTok users have been especially giddy about the return of old-school gym vibes, with one captioning her video, “PRIME Gym time is back babyyyy!!!” while another TikTok user @gymjillyyy declared, “even going to the gym feels like it’s 2016 again >>>”.
It’s not just vibes either. With Google searches for ‘2016 throwback’ reportedly surging by 2456% in the past month, JD Gyms decided to look at what people were actually doing in 2016, what changed after 2020, and what might become the defining workout story of 2026.
High-Intensity Classes Ruled the Roost in 2016

According to JD Gyms’ historical data, the dominant fitness trend in 2016 was simple: go hard, sweat harder, and chase the burn like it owed you money.
High-intensity classes led the charge. Spin, Combat, and Circuits were among the most popular at JD Gyms back then — the kind of sessions where you’d leave feeling like a heroic gladiator… who couldn’t sit down properly for three days.
Back in 2016, the motivation was largely aesthetic and fast-result driven. Gym-goers gravitated to high-energy, cardio-heavy classes designed to torch calories, keep heart rates up, and deliver that “I’ve earned my dinner” feeling.
Music played a starring role too. Fueled by chart dance hits, artists such as Drake, Justin Bieber and Rihanna became unofficial workout partners — not the helpful sort who spot you, but the ones who soundtrack your suffering. Beats became part of the training culture, helping people push through hard intervals and keep the pace when their legs were writing resignation letters.
The Rise of Wellness-Focused Routines

Then 2020 arrived, and the world hit pause.
Lockdown didn’t just stop us getting to the gym — it changed what we wanted from it. With life slowing right down, a lot of people stopped chasing “all-out” workouts and started looking for something they could actually stick with: balance, consistency, and feeling good as well as getting fit.
That shift has remained a major fitness trend for the past six years, with platforms like TikTok and Instagram amplifying workouts that feel less like punishment and more like progress. Pilates, hot yoga, and strength training surged in popularity, appealing to people who wanted to feel better, move better, and keep the habit going for the long haul — not just blitz themselves for six weeks and disappear.
In other words: fewer “I nearly passed out but it was worth it” stories, more “I can move my spine again and my mood is improved” wins.
2026: The Year Hybrid Training Takes Over
So what happens when the 2016 intensity obsession meets the newer wellness approach? JD Gyms believes the answer is hybrid training — and that it’s set to become the biggest fitness trend of 2026.
Hybrid workouts are growing in popularity because they blend strength, cardiovascular conditioning, and agility into one session. For gym-goers, it’s a practical, time-efficient way to train like an athlete without living in the gym — a neat mash-up of the high-energy 2016 style and the more rounded approach that followed.
The search numbers suggest the appetite is there. JD Gyms reports that in the past month alone, UK searches for ‘hybrid fitness’ have surged by 243%, pointing to growing interest in this all-in-one training format.
JD Gyms points to hybrid classes such as JD ENGINE, which are built around a 45-minute, coach-led session combining strength, cardio conditioning, and agility work. The aim is broad: build endurance, improve flexibility, and deliver results — but with the kind of inclusive, group-driven atmosphere that keeps people coming back.
Lee Matthews, Chief Operating Officer at JD Gyms, comments: “At JD Gyms, we’re committed to innovation and inclusivity in fitness. JD ENGINE is the perfect example of this.”
He adds: “It’s an exciting, results-driven class that’s accessible to everyone, no matter where you are on your fitness journey. We can’t wait for our members to experience the energy, challenge and community that JD ENGINE brings to our gyms.”
Why This ‘Fitness Trend’ Actually Makes Sense
The 2016 throwback wave may look like pure nostalgia, but the training shift it’s highlighting is real. People still want intensity — they just don’t want it at the expense of everything else. Hybrid training sits in that sweet spot: hard work, smart structure, and enough variety to keep boredom from killing your motivation.
So yes, 2016 might be back on your screen. But if JD Gyms is right, 2026’s defining fitness trend won’t be a carbon copy — it’ll be the evolved version: the one that gets you fitter without turning every workout into a dramatic near-death experience set to a Bieber chorus.
