Knee Strengthening Exercises for Knee Pain
Train two to three times a week using pain as a guide: keep discomfort at or below three out of ten during exercise and settled within 24 hours. Start with isometric holds and controlled bodyweight work, then progress load gradually.
Strength is the most reliable long term treatment for load related knee pain. This routine progresses from calming an irritable knee through to building genuine capacity.
Stage one: settle the irritation
Isometric holds such as wall sits and static quadriceps contractions often reduce pain while maintaining muscle activity. Use these daily during a flare, alongside a temporary reduction in aggravating activity rather than complete rest.
Stage two: build strength
Progress to controlled movement such as step ups, split squats and leg presses within a comfortable range. Aim for three sets of eight to twelve repetitions at an effort where the last two repetitions are hard but achievable with good technique.
Stage three: return to your sport
Add speed, direction change and impact gradually once strength is comparable between sides. Rushing this stage is the most common reason knee pain returns.
Exercise programme
Work within a comfortable range. Mild discomfort is common, sharp or increasing pain is not.
1. Static Quadriceps Contraction
BeginnerStarting position: Sitting with your leg straight and a small towel roll under the knee.
- 1Press the back of your knee gently down into the roll.
- 2Feel the thigh muscle tighten.
- 3Hold for five to ten seconds, then relax.
Suitable for: Very painful or recently injured knees.
Should be comfortable. Stop if it produces sharp pain.
2. Split Squat
IntermediateStarting position: Standing in a staggered stance, back heel lifted.
- 1Lower straight down until the back knee approaches the floor.
- 2Keep your trunk upright and the front knee tracking over the foot.
- 3Press back up through the front heel.
Suitable for: Building single leg strength once pain is manageable.
Reduce the depth rather than pushing into pain.
3. Sideways Band Walk
BeginnerStarting position: Standing with a resistance band around the thighs, knees slightly bent.
- 1Step sideways keeping tension in the band.
- 2Take ten steps in one direction, then return.
- 3Keep your feet pointing forwards.
Suitable for: Strengthening the hip muscles that control knee position.
Stop if you feel pinching at the front of the hip.
When to stop and get assessed
- Pain above three out of ten during the exercise.
- Swelling increasing after sessions.
- Knee giving way or locking.
When to see a physiotherapist
If your knee is not improving after four to six weeks of consistent strengthening, or if there is swelling, instability or locking, book an assessment.

Frequently asked questions
How many times a week should I do knee exercises?+
Two to three strength sessions a week is a common target, with lighter isometric work daily during a flare.
Are squats bad for the knees?+
Squats are not inherently harmful. Depth, load and progression rate determine whether they irritate a sensitive knee.
Should knee exercises hurt?+
Mild discomfort up to about three out of ten that settles within a day is generally acceptable.
Do I need equipment?+
Not to start. Bodyweight, a step and a resistance band cover most early rehab.

Runner's knee usually reflects more load through the kneecap joint than it is currently prepared for. Reduce running volume temporarily rather than stopping, strengthen the quadriceps, glutes and calves, and rebuild mileage by roughly ten percent per week.
