You sit upright on a sturdy chair with your hands resting on your hips for balance, start with the legs spread wide and feet flat on the floor, then bring the knees in toward the midline before opening them again under control. Because the body is supported and the range is short, the adductors on the inner thigh do most of the work without load passing through the spine or knees. This is a low-barrier exercise that suits beginners, older adults, office workers, and anyone returning to training after a layoff. The adductors are often neglected in standard routines, yet they play a real role in hip stability, walking, squatting depth, and side-to-side control. A seated version lets you isolate that inner-thigh action cleanly, which makes it useful as a warm-up before lower-body work or as a standalone activation drill on days you cannot make it to the gym. The setup matters more than it looks. Sitting tall with hands on the hips keeps your torso from slumping or twisting as the legs move, which forces the work into the hips rather than the lower back. Keeping the feet in contact with the floor and letting them slide inward as the knees come together protects the knee joints and keeps the movement smooth instead of jerky. If the chair is too low or too soft, the hips tilt backward and the range shortens, so pick a firm chair that lets your thighs sit roughly parallel to the floor. To execute it well, think of the knees leading the motion. Squeeze the inner thighs to draw both knees toward each other, pause briefly at the closest point, then widen the legs back to the starting spread with the same control rather than letting gravity drop them out. Keep the movement in the hip joints, not the spine, and avoid bouncing the knees at either end. In practice this exercise appears in seated mobility flows, senior fitness classes, prehab programs for groin and hip strength, and home routines where no equipment beyond a chair is available. Progress it by slowing the tempo, adding a longer squeeze at the top, or increasing the repetitions. Stop short of any pinching sensation in the groin or knee, and reduce the width of the starting position if the outer stretch feels forced. ## Instructions 1. Sit on the front half of a firm chair with your feet flat on the floor and your legs spread wide so the knees point outward. 2. Sit up tall through the crown of your head, place both hands on your hips with elbows out, and brace your abdominal muscles lightly. 3. Check that your weight is spread evenly across both sit bones and that your lower back is in a neutral, upright position rather than rounded. 4. From the wide starting position, squeeze your inner thighs and draw both knees in toward each other, letting your feet slide along the floor toward the midline. 5. Pause for a beat when the knees are as close together as your hips allow, feeling the inner thighs fully contracted. 6. Slowly widen the legs back out to the starting spread, letting the feet slide outward and keeping the movement controlled instead of letting the legs drop open. 7. Exhale as the knees come in and inhale as they travel back out to the wide position. 8. Keep your torso square and your hands on your hips throughout; do not lean or twist to help the knees move. 9. Complete your target repetitions at a steady tempo, then rest before the next set. 10. To reset between sets, bring your feet together under your knees and stand up or simply relax your legs while staying seated. ## Tips & Tricks - A common mistake is rounding forward as the knees come in; the hands-on-hips position only works if you keep your chest lifted, so imagine your hips glued to the chair. - Do not let the heels lift off the floor. Sliding the whole foot along the ground keeps the knees tracking smoothly and protects the inner knee. - If your knees pinch in the groin at the widest point, narrow your starting stance a few inches instead of pushing through the discomfort. - The close position is where the adductors work hardest, so pause there for two or three seconds rather than rushing past it. - Avoid snapping the legs open on the way out; the eccentric, or lowering-style, portion is where a lot of the inner-thigh work happens. - If the chair is cushioned and you sink in, place a folded towel on a firmer seat so your hips stay level and the range stays consistent. - Keep your neck and shoulders relaxed. Many people hunch toward their knees as they squeeze; drop the shoulders away from the ears and look straight ahead. - Breathe steadily instead of holding your breath during the squeeze, which is a common tendency once the inner thighs start working. - Start with a moderate width and moderate repetitions. Chasing an extremely wide stance usually costs you torso position before it adds any training effect. ## Frequently Asked Questions ### Which muscles does Knees In And Out On A Chair work? The primary muscles are the adductors on the inner thighs, which pull the knees toward each other. The glutes and outer hip muscles assist as the legs open back out, and the core works lightly to keep your torso upright. ### Is Knees In And Out On A Chair suitable for complete beginners? Yes, it is one of the most approachable inner-thigh exercises because you are fully supported by the chair and the only resistance is your own leg weight. Beginners should start with a moderate stance width and a slow, controlled tempo. ### Why do my hands rest on my hips during this exercise? Placing the hands on the hips with elbows out makes it harder to slump or twist, which keeps the work in the hip joints. If you notice your elbows dropping forward, your torso is probably leaning as the knees come in. ### Should my feet stay on the floor when the knees come together? Yes, keep the feet in contact with the floor and let them slide inward as the knees draw together. Lifting the feet turns it into a different hip-flexor movement and removes the smooth knee path this exercise is built around. ### What kind of chair works best for Knees In And Out On A Chair? Use a firm, stable chair without wheels, one that lets your thighs sit roughly parallel to the floor when seated. Soft couches or low stools tilt your hips backward and shorten the range you can move through. ### I feel a pinch in my groin at the wide position. What should I change? Narrow your starting stance until the opening position feels like a mild stretch rather than a pinch. You can also slow down and reduce the range on the way out instead of forcing the legs wider. ### Can I add resistance to Knees In And Out On A Chair? Yes, once body weight feels easy you can loop a light resistance band around your knees and press outward against it, or place a small ball between your knees and squeeze it during the in-phase. Progress with tempo and pauses before adding equipment. ### How many repetitions should I do? Fifteen to twenty controlled repetitions per set works well for activation and endurance, since the adductors respond better to higher volumes in this unsupported, low-load format. Focus on a clean squeeze at the close position rather than rushing the count. ### Is this exercise safe for the knees? For most people yes, because the knees stay bent at roughly the same angle throughout and the movement happens at the hips. If you have a current knee or hip issue, keep the range comfortable, move slowly, and stop if either joint complains. ### When is the best time to use Knees In And Out On A Chair in a workout? It works well as a warm-up before squats, lunges, or any side-to-side leg work, and it is also a practical standalone drill on rest days or during long desk sessions when you want to wake up the hips.
