Band Seated Knee Raise
What Is the Band Seated Knee Raise?
Band Seated Knee Raise is an isolation exercise that primarily targets the hips and groin, working the hip flexors that lift the thigh, and also engages the lower abdominals that keep the pelvis steady. It is a beginner-level movement done sitting on a flat bench with a light mini band looped around both feet: one knee lifts toward the chest against the band while the other foot stays planted, then the legs take turns.
The hip flexors are the muscles that swing the leg forward when you walk, lift the foot onto a stair or curb, and bring the legs up into a car or onto a bed. A seated march with no band already trains this pattern, and the band adds resistance that grows as the knee rises, so the top of each rep is the hardest part. Because the bench supports the body and the hands rest beside the hips, the exercise trains the hip flexors without standing, balancing or putting weight through the knees and ankles.
That makes it a good fit for older adults, people returning to exercise after a long break, and anyone who cannot stand comfortably for a full workout, as long as they can sit upright without help. A year-long study of 94 older adults living independently found that those who did not fall had more hip flexor power than those who fell. It measured power on a lab machine and did not test any exercise program, so it shows why these muscles matter rather than what this exercise does. The bench also takes away the balance challenge, so the exercise builds strength, not balance, and works best alongside standing practice once that is safe.
The iliopsoas, the deep hip flexor that runs from the lower spine and pelvis to the top of the thigh, does most of the lifting, especially once the thigh rises above the seat. The rectus femoris, sartorius and tensor fasciae latae help, and the lower abdominals and obliques brace so that the knee lifts without the torso rocking back. The knee stays bent the whole time, which keeps the work at the hip; straightening the knee instead turns it into a quadriceps exercise such as the Band Seated Leg Extension.
If the band makes it too hard to lift the thigh clear of the bench, start with the same movement and no band, lifting only as high as is comfortable. Once two or three sets of 15 slow reps per leg feel easy, use a stronger band, pause longer at the top, or move to standing hip flexor work such as Marching in Place or the Cable Standing Hip Flexion.

Instructions
- Loop a light mini band around the middle of both feet, then sit tall near the middle of a flat bench with your feet flat on the floor, close together, and your knees bent to about 90 degrees.
- Rest your hands on the bench beside your hips with your arms straight and your shoulders relaxed down.
- Brace your stomach lightly and press your left foot into the floor to anchor the band.
- Breathe out and lift your right knee toward your chest against the band, keeping the knee bent, until the thigh rises well clear of the bench.
- Pause for one second at the top without leaning back.
- Breathe in and lower the foot slowly to the floor, resisting the band all the way down.
- Repeat with the left leg while the right foot anchors the band.
- Keep alternating legs until you finish the set number of reps on each side.
Common Mistakes
Leaning back
Throwing the torso back to get the knee higher takes work off the hip flexors and strains the lower back.
Slumping onto the tailbone
Letting the lower back round tips the pelvis back and shortens how far the thigh can lift.
Using too strong a band
A band that is too tight forces a jerky, short lift instead of a smooth rep with the thigh rising clear of the bench.
Letting the band pull the foot down
Dropping the leg back to the floor skips the slow lowering that does much of the work.
Lifting the planted foot
If the other foot does not press into the floor, the band loses its anchor and slides around instead of resisting the lift.
Holding the breath
Bearing down as the knee rises raises blood pressure, so breathe out on the lift and in on the way down.
Injuries
Band Seated Knee Raise is a low risk exercise when performed with proper technique. The body stays seated and supported, and the only load is the weight of the leg plus a light band. Most problems come from the setup: a bench or chair that wobbles or slides, sitting so close to the edge that the hips slip, or a band that rolls off the foot and snaps back.
The usual strain points are the front of the hip and the groin, which can cramp or pinch when the knee is yanked up fast or held high for many reps, and the lower back, when the torso leans back or slumps to help lift the leg. Use a stable bench or a sturdy chair without wheels, sit tall with the hands resting beside the hips, and choose a band light enough that the knee can rise smoothly. Lower the foot under control instead of letting the band pull it down, and breathe out on the lift rather than holding the breath.
Anyone who has had a hip replacement should check with their surgeon or therapist first. A seated knee raise bends the hip past 90 degrees, which the precautions after a posterior-approach replacement usually rule out for the first weeks of recovery. To make the exercise easier, drop the band and lift the knee only a few inches. To progress, use a stronger band, add a pause at the top, or move to standing work such as Marching in Place.
Stop if you feel sharp or pinching pain in the hip or groin, pain that spreads down the leg, dizziness, chest pain or trouble breathing. Mild muscle fatigue at the front of the hip is normal, but pain that lingers the next day means the band was too strong or the set too long, so cut back next time.

Frequently Asked Questions
- Q: Is the Band Seated Knee Raise good for older adults?
Yes. It trains the hip flexors used to lift the feet when walking and climbing stairs, from a seated, supported position with no impact. It builds strength rather than balance, so pair it with standing practice such as Marching in Place once that is safe.
- Q: What kind of band should I use?
A light mini loop band, lighter than you might expect. You should be able to lift the thigh clear of the bench for 10 to 15 slow reps on each leg; if the lift turns jerky or short, the band is too strong.
- Q: Can I do it in a chair instead of a bench?
Yes. Use a sturdy chair without wheels, sit toward the front of the seat so the thigh has room to lift, and rest your hands on the sides of the seat for support.
- Q: Is it safe after a hip replacement?
Only once your surgeon or therapist clears it. The knee raise bends the hip past 90 degrees, which the usual precautions after a posterior-approach replacement rule out during early recovery, so ask which seated exercises fit your restrictions.
- Q: How many reps should I do?
Start with one set of 8 to 10 on each leg and build to two or three sets of 10 to 15. Each rep should be slow enough that you could stop the knee at any point on the way up or down.
- Q: Does it work the abs?
Somewhat. The lower abdominals brace to keep the pelvis still while the leg lifts, but the hip flexors do the moving. For more abdominal work, the Lying Knee Raise is the harder next step.
