—NickyLloyd––Getty ImagesMost people leave the monkey bars behind with childhood. Yet hanging from a bar—right-side up, don’t worry—may be one youthful habit worth picking back up, especially if you spend your days hunched over your desk and phone. (Guilty.)“We look at kids on a playground—what are they doing?” says Australian physiotherapist Daniel Vadnal, owner of FitnessFAQs, who posts instructive videos on Instagram and YouTube. “They don’t need to be told to hang. They just intuitively do it.”A few years ago, Vadnal persuaded his grandmother, now 93, to try a supported hang. That means gripping a bar overhead with straight arms but keeping your feet planted on the floor, rather than dangling your entire body weight. She was skeptical: She hadn’t even raised her arms fully overhead since she was a kid. But after just 30 seconds, she felt taller and looser—and found it easier to reach her kitchen cabinets.Here’s what hanging can do for your body, how to keep your feet planted while you build strength, and why just 30 seconds is long enough. It gives your upper body a stretchAt its simplest, hanging means gripping a secure overhead pull-up bar—the kind that can be installed in a doorway—with straight arms while supporting some or all of your body weight. You remain right-side up: Your hands are above your head, and your feet point toward the floor or remain planted on it. Hanging upside down, known as inversion, is an entirely different exercise. “It’s fairly simple, but it’s not easy,” says Hazel Anderson, a physical therapist and faculty member at the University of St. Augustine for Health Sciences in Austin.Whether your feet stay planted for support or lift off the floor, there are two ways to position your upper body. “The passive hang is, as the name suggests, just relaxed,” Vadnal says. “You’re letting nature, gravity, your body do whatever it wants.” Your shoulders move toward your ears, creating a stretch through the shoulders, arms, and trunk.An active hang requires more effort. “You want to think of trying to bring your shoulder blades down away from your ears,” Vadnal says. That engages the muscles around the shoulders and back, creating more stability. Your elbows remain straight—and your feet can remain planted or off the floor—in either type of hang.Vadnal considers passive and active hangs opposite ends of a spectrum. A passive hang still requires enough muscle effort to remain safely attached to the bar; an active one involves “really making a concerted effort” to hold yourself in position. He recommends choosing the amount of engagement that feels most comfortable for your body.Reaching overhead may feel especially satisfying after all those hours slumped over your desk. Hanging “stretches all the tight muscles that we tend to have through the pecs, through the triceps on the back of the arms, as well as the lats,” Vadnal says. You’ll likely find it leaves you feeling a little taller—and less scrunched up through the shoulders.That doesn’t mean 30 seconds on a bar will permanently correct your posture or treat back or shoulder pain; those claims haven’t been established in strong clinical trials. But hanging moves your upper body into a position it might not visit very often, which helps explain why people often step down feeling looser.It makes your grip workA hang might look passive, but your hands and forearms are busy keeping you attached to the bar. “First and foremost, it supports grip endurance,” Anderson says. “It’s helping with grip strength, but more with the endurance of being able to hold on to the bar.”That endurance is useful for everything from carrying groceries to working toward a pull-up. “The hands, fingers, and forearms serve as a link to our back,” Vadnal says. Strengthening that link helps prepare you to support—and eventually pull—your body weight.Research on short, recreational hangs is limited, and most studies involve climbers. In a small 2026 study, 11 climbers hung on until their grip gave out. As they got tired, their shoulders and other upper-body muscles increasingly pitched in to keep them on the bar.Another randomized trial found that when experienced climbers hung by their fingers for eight weeks, with progressively more weight attached to the body, some measures of grip strength improved. The study involved extra weight and a climbing hold—not beginners attempting a relaxed 30-second hang—but it supports the idea that regularly asking your hands to hold you up can make them better at the job.Grip strength is also widely used as a marker of overall health. “We do know that grip strength is correlated with longevity,” Vadnal says. In a study of nearly 140,000 adults across 17 countries, weaker grip was associated with a higher risk of death and cardiovascular disease.That doesn’t mean hanging longer will make you live longer, Vadnal adds. Think of it as one useful signal—not a path to immortality.Your feet can stay on the floorBeginners don’t need to hover heroically above the ground. When you’re starting out, the bar is—quite literally—low. “I love the addition of a little step stool or platform,” Anderson says. Hold the bar with both hands, bend your knees slightly, and keep enough weight in your feet that the stretch feels manageable. You can gradually allow your arms to support more of you as you become comfortable.“You definitely don’t need to jump straight to 30-second hangs all at once,” Anderson says. She recommends starting with a 10-second supported hang and repeating it three to five times, resting briefly between attempts. From there, work toward the 30-second goal. Vadnal likes three 30-second sets, but only after choosing a variation easy enough to complete with control.Begin with your hands about shoulder-width apart. “That’s most comfortable for pretty much everyone,” Vadnal says, though you can move your hands wider or narrower based on what feels best. Wrap your thumbs underneath the bar to make your grip more secure.If the typical overhand position bothers your shoulders, try a neutral grip, with your palms facing each other. Many gyms have parallel handles that allow for it, and gymnastics rings will rotate to accommodate your joints. Vadnal calls it “probably the most friendly position for the shoulders.”Decide whether a passive or slightly more active hang feels better, and don’t worry about matching someone else’s position. Forcing your shoulders farther overhead than they can comfortably go may leave them sore or irritated, Vadnal says. Let your range of motion improve gradually instead.Most importantly, remember to breathe. Anderson advises using “slow, controlled breaths” and making sure you’re not holding your air in, whether you’re a beginner or an expert. It’s easy to get so focused on staying on the bar that your whole body clenches up; a few steady breaths can help you relax into the hang.“Don’t chase the clock,” Anderson says. If your form changes or you can no longer control the hang, put your feet down, rest, and try again.Know when to let goHanging should feel like work—not like you’re about to injure yourself. “We should feel a stretching sensation; we should feel fatigued,” Vadnal says. “We shouldn’t feel pain.” Put your feet down if you experience sharp or persistent pain, numbness, tingling, or weakness.Those symptoms are signs to stop, not to push through. Talk to a doctor or a physical therapist before trying again. Some people should seek guidance before they ever reach for the bar: Anderson recommends medical clearance for anyone who recently had shoulder surgery or an injury involving the neck, shoulders, elbows, wrists, or trunk. The same applies to people with shoulder instability, pain when reaching overhead, cardiovascular concerns, or uncontrolled high blood pressure. Osteoporosis doesn’t automatically make hanging off-limits. But because a fall could have more serious consequences, Anderson says, it’s particularly important to keep your feet supported and get personalized guidance.Anderson recommends practicing two or three times a week on nonconsecutive days, which allows the muscles to recover. There’s no need to progress from zero hanging to auditioning for Cirque du Soleil. Add time or body weight gradually, and take a day off if your hands, forearms, or shoulders remain unusually sore.If you like hanging, Vadnal suggests keeping a bar somewhere you’ll regularly see it, like in your laundry room. “It’s like daily hygiene,” he says. “You brush your teeth; hanging is a good thing, too.”
