Are weighted vests anything more than a passing trend?
They show up every few years. First it was rucking and endurance folks strapping them on. Then came the fat-loss claims, backed by headlines that made them sound like the missing piece in any training plan. More recently, Hyrox has given weighted vests another round of attention.
The short answer: if you are already lifting weights and moving regularly, a weighted vest is unlikely to change much for you. But depending on your goals, it might still have a place in your routine. Here’s what the evidence says.
The walking question
I bought my first weighted vest a few years ago without really checking the literature. It felt obvious — add weight to your walks, get more out of them. Intuition is great until you look at the data.
A 2006 study with 10 participants did find some effect on oxygen consumption when people walked faster while wearing a vest. But another study in older adults found that wearing one didn’t do much more for physical function than going without it. There is evidence that weighted vests can improve running economy for distance runners and boost certain performance markers in soccer players. For walking, though, the health benefits don’t appear to be supercharged by the extra load.
Here’s what I tell my clients: if your goal is simply more movement and better cardiovascular health, adding a vest to an easy walk adds complexity without a clear payoff. You get more bang for your buck from walking slightly faster or adding a few incline minutes.
The weight loss claims
A 2024 paper examined the metabolic cost of walking with weighted vests and found that energy expenditure increased in a nonlinear fashion, roughly proportional to the load carried. The media ran with headlines like “Weighted walking increases calorie burn by over 40%!” — but the details matter.
The study participants walked wearing loads equal to 22%, 44%, or 66% of their body mass. That is not a single vest. That is multiple vests, or one very heavy one. In another study on older adults, light vests were defined as 1% of body weight and heavy ones at 11%. Unless you are planning to carry more than 40% of your body weight for long stretches, the extra calorie burn comes down to a few calories here and there.
For most people trying to lose weight, that is far from a game changer. The difference between wearing a vest worth $50 or nothing at all will not move the needle on body composition as much as your daily step count or protein intake will.
What about longer-term results?
In one study of older adults, those who wore a “heavy” vest (11% of body weight) lost more body weight and fat mass while gaining a small amount of fat-free mass. But in a separate study where participants wore a weighted vest for roughly 10 hours per day alongside a low-calorie diet, there was no difference in weight loss or body composition changes between the vest group and the control group.
The interesting finding came afterward: a follow-up paper showed that the vest wearers maintained their weight loss better over the two years following the study. So the benefit may show up more in long-term adherence than in immediate results.
Who should buy one?
If you are new to training and want to add resistance to bodyweight exercises — squats, lunges, push-ups — a vest is a simple way to progress without learning a barbell movement. If you do Hyrox or rucking, a weighted vest is part of the sport, so it makes sense.
But if you are already strength training two or more times per week and your cardio is covered, the vest is an optional add-on, not a necessity. We still need more research to say anything definitive beyond that.
The Science, Simplified
A weighted vest won’t dramatically transform your walking workouts or your calorie burn unless you are carrying a serious load — 10% of your body weight or more. For most lifters already in the gym, the extra complexity isn’t worth it. But if you want to progress on bodyweight movements or train for Hyrox, one can be a practical tool. Start light, see how it feels for a few weeks, and judge from there.
The research won’t make you strong by itself. The next workout will. Pick whether the vest fits your routine tonight, try it for six weeks, and let the results decide. That is the whole secret, and it has always been.
