Seated Knee Lift Exercise for Abs and Hips

If you’ve been looking for a safe way to build strength without getting down on the floor, this one’s for you. All you need is a sturdy chair and eight minutes. No equipment, no gym, no fancy moves, just slow, controlled knee lifts you can do right at home.

This exercise for abs and hips works two areas at once: your core (the muscles around your stomach and lower back that help you sit and stand up straight) and your hip flexors (the muscles at the top of your thighs that lift your knee up toward your chest, like when you climb a stair). Keeping these muscles strong makes everyday movements, getting out of a chair, climbing steps, walking, feel easier and safer.

Move slowly. Keep your back tall and feet flat on the floor.

How to Do It

Sit upright in a sturdy chair with both feet flat on the floor.
Slowly lift your right knee toward your chest, only as high as feels comfortable.
Hold for 2 seconds, then lower your leg back down slowly and with control.
Switch to your left leg. Keep alternating legs at a steady, unhurried pace.
Rest for 30 seconds between rounds. Stop right away if anything feels uncomfortable.

Move slowly throughout, and keep your back tall against the chair the whole time.

Why Exercise for Abs and Hips Is Good for You

Builds Strength in Your Hips and Stomach Muscles

Every time you lift your knee, you’re asking your hip flexors and lower stomach muscles to do the work. Over time, this makes them stronger, and stronger hip and stomach muscles mean it takes less effort to stand up, climb stairs, or get in and out of a car. Because you’re seated and supported, you get this strengthening benefit without any strain on your joints.

Helps You Sit Up Taller and Straighter

Sitting for long stretches, whether at a desk, on the sofa, or in a car, tends to round the shoulders and slump the lower back. This exercise engages the muscles that hold you upright, so with regular practice, sitting tall starts to feel more natural instead of like something you have to think about.

Gets Your Blood Moving

Lifting your legs repeatedly encourages blood to circulate more freely through your lower body. Good circulation matters more as we age, since sitting still for long periods can leave the legs feeling stiff, heavy, or swollen. A few gentle minutes of movement like this can help keep things flowing.

Helps You Stay Steady and Independent

Strong hip and core muscles are the foundation for balance. They’re what keep you steady when you reach for something on a shelf, step over a curb, or catch yourself if you stumble. Building this strength now is one of the simplest ways to protect your independence and lower your risk of a fall.

Make It Easier or Harder

Easier: Lift your knee just slightly, keeping your foot close to the floor.
Harder: Hold each lift for 5 seconds before lowering your leg back down.

Safety First

Only lift your knee as high as feels comfortable, and never push through pain. Stop immediately if you feel pain, dizziness, or discomfort in your chest.
