When the health firm Peloton added weighted-vest lessons to its streaming train choices in Could 2025, its members rejoiced, says teacher Rebecca Kennedy. “They have been like, ‘Lastly! You answered my prayers’!” she laughs. “The urge for food has been actually wild.”
Strapping further weight to your physique whereas understanding is nothing new; the observe of “rucking”—strolling with a weighted backpack—has roots in army coaching and has been proven to assist enhance endurance and construct muscle energy and stamina.
However sporting a weighted vest to train has surged in recognition over the previous few years, with the worldwide marketplace for weighted vests predicted to develop from $199 million in 2024 to $313 million by 2031.
Including mechanical load onto your skeleton means your muscle tissue should work more durable for help, Kennedy says. “Our metabolic output naturally will increase, as a result of the load is heavier. We’re getting greater use of oxygen, we’re burning extra energy, we now have extra pressure over our whole physique, and particularly as a result of it’s on our trunk, our postural muscle tissue are working fairly a bit extra.”
Put merely, sporting a weighted vest is a “nice option to, on the very core factor of it, enhance the problem of whichever train you’re doing,” says Mathias Sorensen, an train physiologist on the College of California San Francisco (UCSF) Human Efficiency Middle.
When to put on a weighted vest

Mike Hayes, an authorized private coach at Crunch Health in New York, wears his vest throughout power coaching, for strikes like push-ups, pull-ups, leap squats, and lunges. “I do it to make my body-weight workout routines a little bit bit more durable, so I’m required to exert much more energy and power,” he says. From an ergonomic perspective, explains Sorensen, “it’s rather a lot simpler to placed on a weighted vest than it’s to have any person put a large plate in your again to create the identical impact.”
However there are some actions that aren’t suited to weighted vests, Kennedy says, like Pilates, yoga, any kind of inverted actions, and something with fast twisting, like pickleball or tennis. And ensure you take it off in your cool-down stretch, too. “Anytime you’re making an attempt to load a stretch, it must be by means of exhale and time, versus including a weight to it,” she says.
How one can get began
As with all change to your train routine, go sluggish. For those who roll off the bed “and also you go purchase the 30-pound weighted vest on Amazon and begin doing 30 squats a day, there’s an irrefutable chance that an damage goes to occur,” Sorensen says.
The final rule of thumb, Kennedy explains, is to decide on a vest that’s 5-10% of your physique weight. Put on it for 10 minutes the primary time to see how your physique responds, then enhance your utilization progressively. “I would put on it two or three days in week one,” she says.

Although weighted vests are usually protected for almost all of individuals, Kennedy says, search clearance out of your physician in case you have points with steadiness, or neck, shoulder, or again accidents; inserting further stress on the backbone can exacerbate situations like degenerative disc illness. Pregnant ladies, notably within the second and third trimester, ought to keep away from including extra load to their trunk.
Weighted vests and bone well being
As we become old, we start to lose bone mass or density; ladies are extra seemingly to develop osteoporosis than males, as a result of estrogen, which performs a vital position in defending bones, decreases sharply in menopause.
Whereas it’s well-established that train will help strengthen our bones as we age, the analysis on weighted vests and bone well being is scant. Most research have been small with various or unclear outcomes, and even the current 12-month INVEST in Bone Well being trial, which adopted 150 older adults, discovered that each day weighted vest use didn’t forestall weight loss-associated bone loss on the hip.
“There’s a whole lot of buzz across the weighted vest, that it is this bone-density hack,” says Michele Hen, a board-certified orthopedic scientific specialist and assistant professor of utilized train science on the College of Michigan Faculty of Kinesiology. “I simply do not assume that the proof has supported that right now.”
Nonetheless, she says, “if that vest is getting somebody to be extra energetic, I believe that’s nice.”
Upcoming analysis
As extra folks strap in for the primary time, analysis into the potential effectiveness of weighted vests continues to come back down the pike.
Kristen Beavers, an affiliate professor within the division of well being and train science at Wake Forest College and one of many researchers within the INVEST trial, says the staff is presently engaged on different research associated to weighted vests, together with the impression on muscle and the distinction in outcomes between women and men.
In March, they revealed a small pilot research suggesting that sporting a weighted vest throughout energetic weight reduction could assist folks preserve that loss over the long run.
“I don’t assume the story is completed,” she says.
