An Asian squat is a deep squat where you lower your hips all the way down near your ankles while keeping both feet flat on the ground. Unlike a partial squat or a toe-balanced crouch, your heels stay planted, your weight distributes evenly across your whole foot, and you can hold the position comfortably for minutes at a time. The name comes from its widespread use as a resting posture across East and Southeast Asia, where people commonly squat this way while eating, waiting, socializing, or working.
If you grew up sitting in chairs, there’s a good chance you can’t do this without toppling backward or lifting your heels. That difficulty isn’t about your genes or your skeleton. It’s almost entirely about practice.
What Makes It Different From Other Squats
The defining feature is the flat foot. In a heels-up squat, you balance on the balls of your feet, which is inherently less stable and puts more strain on your knees and toes. A flat-footed deep squat shifts your center of gravity lower and distributes your weight more evenly, letting you sit in the position without muscular effort to stay balanced. Your hips drop below your knees, your thighs press against or near your calves, and your torso stays relatively upright.
This is not an exercise position. It’s a resting position. In many parts of the world, it replaces sitting in a chair entirely for daily activities. Roughly 40% of men and 68% of women in a large Beijing study reported squatting for at least an hour a day at age 25, giving a sense of how routine this posture is in cultures that use it.
Why Some People Struggle With It
The most common assumption is that Asian populations are genetically built for deep squatting, with different joint structures or bone proportions. Research from the University of Waterloo tested this directly by comparing the maximum knee bend in Caucasian participants and Canadian-born East Asians who grew up in a chair-sitting culture. The two groups showed no meaningful difference: East Asians born in Canada averaged about 152 degrees of peak knee flexion, while Caucasians averaged about 150 degrees. The physical capacity was the same. The difference is cultural, not innate.
What actually limits most people is ankle flexibility. To keep your heels on the ground in a deep squat, your ankles need enough range of motion (called dorsiflexion) to let your shins angle sharply forward over your toes. If your calf muscles are tight from years of wearing shoes and sitting in chairs, your ankles can’t flex far enough, and your heels pop up or you fall backward.
Hip flexibility matters too. Tight hip flexors and inner thigh muscles can prevent your hips from dropping low enough between your legs. And your body proportions play a role in how the squat feels. People with shorter thighbones relative to their torso can stay more upright naturally, making the position easier to balance. Longer thighbones push your center of gravity forward, which means your ankles and hips have to compensate with even more flexibility to keep you from tipping. None of these proportions make the squat impossible, but they change how much mobility work you might need to get there.
How It Affects Your Digestive System
Deep squatting straightens the path between your rectum and your anal canal, which makes bowel movements easier. When you sit on a standard toilet, the angle between these two structures is about 100 degrees, creating a kink that requires straining to push past. In a full squat, that angle opens to roughly 126 degrees. The greater hip flexion relaxes the muscle that normally maintains that kink, creating a straighter channel that lets gravity do more of the work.
This is the same principle behind popular bathroom stools that elevate your feet while you sit on the toilet. They mimic some of the hip flexion you’d get from squatting, though they can’t fully replicate the angle. Cultures that use squat toilets have long relied on this alignment without thinking about it.
Effects on Your Pelvic Floor
The deep squat position engages the muscles that support your bladder, uterus, and rectum in a way that strengthens them over time. These pelvic floor muscles work by pulling against a set of internal ligaments to open and close the urethral and anal tubes. When those ligaments are loose or the muscles are weak, the system can’t hold urine or stool effectively against internal pressure.
Squatting-based exercises have shown promise for strengthening these muscles and the ligaments they attach to. In one study of children with bladder and bowel control problems, a four-month program of squatting-based pelvic exercises resolved their symptoms. The mechanism works in both directions: squatting strengthens the muscles that hold things closed when you need continence, and it also trains the muscles that open things up when you need to go.
What About Your Knees?
This is where the picture gets more nuanced. The Beijing Osteoarthritis Study found that prolonged daily squatting was associated with higher rates of knee arthritis, particularly in the joint between the shinbone and thighbone. People who squatted two or more hours per day at age 25 had roughly double the odds of developing knee arthritis later in life compared to those who squatted less than 30 minutes a day.
Context matters here. These findings came from elderly participants who had spent decades squatting for hours daily, often during manual labor like farming and washing. Squatting briefly throughout your day or using it as a mobility practice is a very different load on your joints than spending three hours crouched in a rice paddy. For healthy knees, short periods of deep squatting appear to be safe and may even help maintain joint range of motion. If you already have knee pain or cartilage damage, approach deep squatting cautiously and pay attention to what your knees tell you.
How to Work Toward a Flat-Footed Squat
If you can’t get into a full deep squat with your heels down, the bottleneck is almost always ankle and hip mobility. Start with your ankles. Stretching your calves targets two key muscles: the larger one that crosses your knee joint and a deeper one underneath it. A simple wall stretch with your knee straight hits the outer muscle; bending your knee while keeping your heel down shifts the stretch to the deeper one. Do both. Consistent stretching over weeks will gradually give your ankles the range they need.
For your hips, any stretch that opens the front of your hip and your inner thighs will help. Lunges, butterfly stretches, and deep lunge holds are all useful. The goal is to let your pelvis drop between your legs without your lower back rounding excessively to compensate.
While you build flexibility, practice the squat itself with support. Hold onto a doorframe, a pole, or the edge of a counter, and lower yourself into the deepest squat you can manage with your heels on the ground. Let the support take some of your weight so you can sit in the position without straining. Even a minute or two a day trains your nervous system to accept the range of motion. You can also place a small wedge or rolled towel under your heels to reduce the ankle demand while you work on flexibility.
Progress is slow but steady. Most adults who commit to daily practice can achieve a comfortable flat-footed squat within a few weeks to a few months, depending on their starting mobility. Children and teenagers typically pick it up much faster because they haven’t yet lost the flexibility they were born with.
