Knee Osteoarthritis Starter Exercise Guide

1. Quad Sets

What it helps: Wakes up the quadriceps — the big thigh muscles that support and control your knee. Getting them firing is the foundation of a strong, steady leg.

How often: 2-3 sets of 10, a few times a day.

1. Sit or lie with your leg straight.
2. Tighten the muscle on top of your thigh, pressing the back of your knee down.
3. Hold briefly, then relax.

2. Glute Squeezes

What it helps: Wakes up the glutes — the big muscles that steady and support your hip. Getting them firing again is the first step toward a hip that feels stronger and carries you with less strain on the joint.

How often: 2-3 sets of 10, a few times a day.

1. Lie or sit comfortably.
2. Squeeze your buttock muscles together.
3. Hold a few seconds, then relax.

3. Heel Slides

What it helps: Coaxes gentle bending back into the knee — restoring the motion you need for stairs, sitting, and getting in and out of a car.

How often: 2-3 sets of 10, a few times a day.

1. Lie on your back with your legs straight.
2. Slowly slide your heel toward you, bending the knee.
3. Slide it back down.

Tip: Only go as far as is comfortable.

4. Straight Leg Raises

What it helps: Builds quad and hip strength while the knee stays straight, so the muscle works hard without stressing the joint.

How often: 2-3 sets of 10, once or twice a day.

1. Lie down with one leg bent and the other straight.
2. Tighten your thigh and lift the straight leg a few inches.
3. Lower slowly.

Tip: Keep the knee straight as you lift.

5. Terminal Knee Extensions

What it helps: Trains the quad to lock the knee out fully straight — the strength you rely on every time you stand and step.

How often: 2-3 sets of 10-15, once or twice a day.

1. Anchor a resistance band to something solid at about ankle height — a table leg or a door anchor.
2. Loop the free end around the back of your knee, then face the anchor and step back until the band is taut.
3. Stand with that knee slightly bent, weight through the foot.
4. Tighten your thigh and push the knee straight against the band's pull.
5. Let the knee bend slowly back to the start.

Tip: The band pulls the knee forwards; your job is to resist it. Nothing goes around your foot.

6. Heel Raises

What it helps: Strengthens the calf and steadies your balance, rebuilding the push-off that drives walking.

How often: 2-3 sets of 10-15, once or twice a day.

1. Stand holding a counter.
2. Rise up onto your toes.
3. Lower slowly.

7. Walking Program

What it helps: Comfortable, frequent walking keeps the joints loose, builds your stamina, and rebuilds confidence on your feet. Little and often beats long and tiring.

How often: throughout the day.

1. Take short walks at a comfortable pace.
2. Increase your distance gradually as you feel able.

Tip: Use your assistive device as directed.

8. Sit-to-Stand

What it helps: Trains the exact strength you use to rise from a chair, a toilet, or a car. Stronger here means more independence and less of a struggle on tough days.

How often: 2-3 sets of 8-10, once or twice a day.

1. Sit at the edge of a sturdy chair.
2. Lean slightly forward and stand up.
3. Lower yourself back down with control.

Tip: Use your arms for support as needed.
