In 2025, losing weight doesn’t have to be about doing more. How? We now have the resources to increase the results from what you’re already doing. Instead of extreme workouts, people are now leveraging science and performance gear to elevate routine exercises into efficient fat-burning activities.
The weighted vest, a seemingly simple yet remarkably effective exercise tool, is currently making waves in the weight loss industry. Wearing one lets you add intelligent resistance on your body, helping you burn more calories, strengthen your heart, and spark real, sustainable weight loss.
In a previous post, we’ve talked about the science-backed weight loss benefits of a weighted vest. Here, we present 8 strategic steps for getting the most out of your weighted vest for fat loss, starting today!
How Do Weighted Vests Help You Lose Weight? Gravitostat Theory & Aion’s Cutting-Edge Research
But first, why and how does weight loading through a weighted vest work for weight loss? To start, the idea is rooted in both science and common sense: increasing the load your body carries raises energy demand. But there's more to it than that.
This study on weight loading introduced the concept of the “Gravitostat”—a built-in body weight regulation system. The study supports that by making the body "think" it weighs more (via weighted vests), it triggers fat loss while preserving muscle mass.
Aion confirms this power of added load by gathering our own data. In a series of tests using WHOOP wearable bands, 3Db motion capture, and force plate technology, we studied the effects of wearing the Aion vest during daily activities and workouts. Here’s what we found:
Calorie Burning Increased
Walking Test:
- 18% more caloric expenditure (548 with vest vs. 463 without)
- Longer time spent in fat-burning Zone 2 (56% with vest vs. 26% without)
HIIT (High-Intensity Interval Training) Test:
- 69% more caloric expenditure (371 with vest vs. 219 without)
- Higher maximum heart rate (167 bpm with vest vs. 148 bpm without)
- Higher strain score (9.3 with vest vs. 6.6 without)
Cardiovascular Performance Improved
Walking Test:
- 4.8% higher average heart rate (109 bpm with vest vs. 104 bpm without)
-
More time spent in heart-friendly Zone 2 (56% with vest vs. 26% without)
HIIT Test:
- 20% higher average heart rate (124 bpm with vest vs. 103 bpm without)
- More time spent and higher intensity cardiovascular training zones
Muscle Building and Mobility
The vest engages and strengthens muscles through every movement. Wearers experienced no significant difference in movement patterns between wearing and not wearing the vest.
Recovery Support
Beyond just weight, Aion’s compression and active heat retention work synergistically. These features significantly increase circulation, gently elevate core temperature, and promote healthy detoxification, magnifying your body’s natural recovery processes.
8 Smart Steps to Using a Weighted Vest to Lose Weight in 2025
Below is an 8-step science-backed approach to using a weighted vest to lose weight in 2025. With this, you don’t have to overhaul your lifestyle to see results—you just need to make your current routine work harder for you.
Step 1. Choose the Right Vest
To maximize weight loss, look for comfort and performance. Your vest needs to move with you, not against you. The right vest allows you to train hard and safely without altering your natural movement patterns. Choose the vest that:
- Has a snug, low-bounce fit allowing a full range of motion
- Is made with premium, flexible materials that won’t chafe and move with you
- Weighs approximately 3-5% of your body weight
- Is comfortable, durable and antimicrobial
Step 2. Take Your Daily Walk
The most accessible way to start using your weighted vest? Just take a walk daily. As our tests show, walking with a weighted vest not only increases your calorie burn but keeps you in the fat-burning Zone 2 longer.
Begin with 20-30 minutes and slowly increase the time or distance to allow your body to adapt. Let the extra resistance gradually raise your heart rate, improve endurance, and torch fat. Additionally, you’ll feel more engaged, mindful, and accomplished even with these short walks.
Step 3. Use it in Zone 2 Cardio Training
Zone 2 is the heart rate level your body reaches when performing a certain physical activity. At this level, where your heart rate is 60-70% of your maximum, fat loss is at its maximum. Use a weighted vest like Aion’s to reach your Zone 2 heart rate faster and stay in that optimal zone for longer without the need to push your body harder.
Step 4. Use it in Your Everyday Tasks
Use your vest to turn any routine task into a fat-burning moment. It doesn’t have to be a workout session—you can wear your Aion vest while:
- Cooking dinner
- Folding laundry
- Shopping
- Walking the dog
- Tidying up
With Aion’s stylish and comfortable vests, you can turn low-effort daily movement into high-impact fat-burning opportunities. Human biologist and biohacker Gary Brecka wears his Aion weighted vest, both the men’s workout and boardroom vest, all the time! Here’s his take on adding weighted vests to your routine:
“You can take the workouts you're already doing and get more out of doing the same workout. When I first started incorporating a weighted vest into my workouts, the impact was immediate. I noticed improvements in my stamina, my energy levels, and my strength almost overnight. But don't just take my word for it. Adding weight to your walk doesn't just make it harder, it makes it smarter.” - Gary Brecka
Step 5. Upgrade Your Workouts Without Overtraining
Already have a workout routine? Whether it’s HIIT, strength training, or circuit workouts, just add your weighted vest. Even with the same time and effort, you can amplify your caloric burning. This is especially useful if you are experiencing a workout plateau—a slowing down or stalling of your workout progress due to your body adapting to your workout routine. You too can reignite your weight loss like Adam below.
Step 6. Build Muscle While Burning Fat
Let the added weight of the vest make your muscles work harder. Whether you're squatting, lunging, or just walking uphill, the added load will challenge your muscles during every move. Over time, this added resistance builds strength and lean mass, which boosts your metabolism and helps you burn more calories, even at rest.
Step 7. Allow Recovery
As with any exercise activity, listen to your body and don’t overdo it. Allow time for your body to rest and rebuild after a workout. If you choose a weighted vest from Aion, your vest will actually support your recovery with built-in compression and active heat-retention. These features aren’t just nice add-ons; they create a powerful synergy that amplifies blood flow and post-workout recovery. Wear your Aion vest for a while after an intense workout or during mobility sessions to actively boost circulation, ease soreness, and accelerate your body’s natural repair processes. This means less downtime and faster progress towards your weight loss goals.
Step 8. Stay Consistent
Long-term weight loss is not about perfection—it’s about showing up consistently. You don’t need to crush a workout every day or hit some elite benchmark to see real results. What matters is making small, repeatable decisions that compound over time. Use your weighted vest to move regularly and let the vest amplify the effort you’re already making.
With your weighted vest, you:
- Burn more, even if your routine stays the same
- Build strength passively, through regular wear
- Avoid injury and fatigue because you're not overtraining
