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

Mike Hayes, a licensed private coach at Crunch Health in New York, wears his vest throughout strength training, 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 drive,” 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 anyone 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 form of inverted actions, and something with fast twisting, like pickleball or tennis. And be sure to take it off to 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.
get began
As with all change to your train routine, go sluggish. When you roll away from 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 step by step. “I’d put on it two or three days in week one,” she says.

A hard and fast weight vest will match extra snugly and jostle round much less as you progress, whereas an adjustable one permits you to progressively enhance the resistance as you get stronger.
Although weighted vests are typically protected for almost all of individuals, Kennedy says, search clearance out of your physician when you have points with steadiness, or neck, shoulder, or again accidents; putting extra stress on the backbone can exacerbate conditions like degenerative disc illness. Pregnant girls, significantly within the second and third trimester, ought to keep away from including extra load to their trunk.

Whereas it’s well-established that exercise can help strengthen our bones as we age, the analysis on weighted vests and bone well being is scant. Most studies have been small with various or unclear outcomes, and even the latest 12-month INVEST in Bone Health trial, which adopted 150 older adults, discovered that day by day weighted vest use did not prevent weight loss-associated bone loss on the hip.
“There’s lots of buzz across the weighted vest, that it is this bone-density hack,” says Michele Chicken, a board-certified orthopedic medical specialist and assistant professor of utilized train science on the College of Michigan Faculty of Kinesiology. “I simply do not suppose that the proof has supported that right now.”
Nonetheless, she says, “if that vest is getting somebody to be extra lively, I feel that’s nice.”
Upcoming analysis
As extra individuals 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 group 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 study suggesting that sporting a weighted vest throughout lively weight reduction might assist individuals keep that loss over the long run.
“I don’t suppose the story is finished,” she says.
