The Aion Vest: Gary Brecka’s Shortcut to Getting More Output From Every Workout
Gary Brecka is widely regarded as the world’s leading biohacker, famed for unlocking the secrets to better energy, sleep, focus, and overall health.
The viral human biologist has been welcomed onto some of the most respected podcasts — including Jake Humphrey’s High Performance and The Joe Rogan Experience — to share his pearls of wisdom.
Brecka also delivers insights through his own show, The Ultimate Human, which has over 500,000 subscribers on YouTube alone. So when he shares a training tip, it tends to be worth hearing.
The longevity expert has now revealed his secret weapon for next-level resistance workouts: the Aion Vest.
Here’s why Brecka has hailed it as having an “immediate” impact on his training — and how to strap into the progression tool that’s suddenly appearing on torsos everywhere.
Introducing the Aion Vest
The Aion Vest is a weighted training aid designed to biostack your movement. I know what you’re thinking, “Weighted vests have been around for ages, no?”
That’s true — but not a single market competitor can rival the Aion’s credentials. In fact, this model is the world’s first to feature a triple-threat of crucial elements: weight, compression, and heat capture strategically distributed across your upper body.
It’s a patented principle the brand calls “Dynamic Resistance™”, and one that spells big benefits for your training.
Optimally loaded with weight that increases with size, the Aion Vest engages and strengthens muscles with every movement, adding an extra layer of challenge without prolonging workout duration.

While the weight is creating those all-important microtears in your muscle fibers, Aion’s fabrics are working double time to capture the heat against your skin.
That smart insulation, coupled with the added resistance, helps you burn calories faster while practicing the all-important method of progressive overload.
A true compression fit is the final piece of the jigsaw. By surrounding your core — instead of sagging as you move — the Aion Vest promises comfort, security, and increased muscle activation that builds balance and posture.
All that functionality is wrapped up in a hard-hitting design that makes you look — and feel — bulletproof. Put simply, there’s no other weighted vest quite like it.
Why It’s Gary Brecka’s Training Staple
Almost every gym-goer incorporates some form of bodyweight or cardio exercise into their training. Whether that’s push-ups, pull-ups, HIIT movements, running, or hiking, at some point you’re bound to hit a plateau.
Our muscles get comfortable with the challenge, which is why ramping up the intensity is crucial for perpetual progression.
For Gary Brecka, the Aion Vest represents a clever means to introduce that extra load while squeezing every last ounce of gains out of each session.
“You can take the workout you’re already doing, and get more out of doing the same workout,” he said on The Ultimate Human podcast.
“When I first started incorporating an (Aion) weighted vest into my workouts, the impact was immediate. I noticed improvements in my stamina, my energy levels, and my strength almost overnight.”
As a firm member of the evidence-based community, Brecka doesn’t expect people to simply take his word for it.
Training in an Aion Vest burns up to 40% more calories when performing high-intensity movements. Most crucially, it can return 25% more output from the same workout, achieving faster results without sapping more of your time.
“Adding weight to your walk doesn’t just make it harder; it makes it smarter,” he added.
“Research actually shows that wearing a weighted vest during exercise like rucking or walking can lead to an increase in peak running speed, a 20% increase in leg stiffness, and a 40% improvement in oxygen efficiency after just five days of training.
“Now, you might think these numbers are small, but the long-term benefits of rucking with a weighted vest are significant.”
The Bottom Line
So there we have it — high praise from the king of biohacking himself. If you want to stack your gains with an Aion Vest, you’ve got options.
The Men’s Workout Vest comes in Black and Green colorways, with sizes stretching from Small through XXXL. As the size increases, so does the weight.
Each option is fractionally loaded to hit between 3-5% of body weight, evenly distributing the load across the upper body.

The Women’s equivalent offers the same perks, but in sizes XS through XL and a Black/White split color replacing the Green.
Prices range from $329 to $409, depending on size. Is it an investment? For sure. Is it a smart one? According to Gary Brecka, it might just be the best one you ever make.
