Strong muscles around the knee act like shock absorbers: they take load off the joint, keep the kneecap tracking well and help the knee stay stable when you walk, climb stairs or play sport. The good news is that you don’t need a gym to start building that strength.
These four exercises are a sample from Stage 3 (strengthening) of my 3-stage knee rehabilitation guide. All you need is a mini band, a sturdy bench or chair, and a low step.
Before You Start
- Warm up with a few knee stretches and quad activation exercises
- Keep your knee in line with your second toe; don’t let it cave inwards
- Push through your heel rather than your toes
- No sharp pain inside the knee; muscle fatigue is fine
4 Knee Strengthening Exercises
1. Sit to Stand With a Band
Sit on a bench or sturdy chair with a band around your knees. Breathe out and push through your heels to stand up, keeping gentle outward pressure on the band. Pause, then lower yourself back down slowly with control rather than dropping onto the seat. A higher seat makes it easier.
2. Step Up
Stand in front of a low step with one foot on it. Lean slightly forward and step up slowly, keeping the front knee in line with your toes, then lower back down with control. Keep the step low to begin with.
3. Lateral Step
Stand side-on to a low step with one foot on it. Step sideways up onto the step, keeping the supporting knee slightly bent, pause, then step back down slowly. It trains the knee to stay stable when you move sideways.
4. Single Leg Bridge
Lie on your back and lift into a bridge. Straighten one leg in line with the other knee and hold without letting your hips drop. The hamstrings and glutes are key knee stabilisers, so knee rehab isn’t only about the quads.
How to Progress
Start with the easiest versions and slow, controlled reps. You can progress by lowering the seat, using a higher step, going single-leg or adding load, but only when the easier version feels easy with perfect form. The full guide rates every exercise from 1 (beginner) to 3 (advanced), with the sets, reps and progressions for each level, including box squats, lunges and ball hamstring curls.
If stairs are your main problem, read knee pain going down stairs: exercises that help. Weak side glutes often let the knee cave inwards, so also try these gluteus medius exercises.
