Best Leg Exercises
Intermediate Level

What are the best leg exercises for knee pain?  It's such a common question and over many years, working with hundreds of patients, I’ve pulled together a selection of mid-level exercises that I have found work well for all sorts of knee pain.

Here you will find some of the best leg exercises incorporating strengthening, balance and stretching exercises. Muscles can get weak and tight over time, or after an injury without us really noticing. When this happens, it changes the way the knee moves and how the forces go through the knee which causes pain. Most causes of knee pain will benefit from knee exercises.

The exercises here are mid-level exercises. If they feel too strenuous or your knee movement is quite restricted, try simpler exercises first. If you are looking for something more challenging, visit the advanced exercises section.

Best Leg Exercises For Strength

Here you will find six of the best leg exercises for increase strength. Strengthening the leg muscles is one of the best ways to reduce most causes of knee pain. You should notice an improvement after 3-4 weeks of doing these exercises, if you do them regularly.

1) Bridging: Stage 1

Purpose: One of the best leg exercises for increasing all-round strength and control - strengthens the hamstrings whilst also working the quads and buttock muscles. Also helps develop core strength and stability

Starting Position: Lie on your back with both knees bent about 90° and your feet on the floor/bed

Action: Clench your buttocks and lift your bottom off the bed as high as you can without arching your back. Hold for 3-5 seconds and slowly lower

Repetitions: Repeat 10-25 times, 1-2x daily

Note: 1) Keep your back straight – don’t let it arch as you lift up, make your bottom doing the work
2) Don’t hold your breath – keep breathing normally
3) Don’t let your knees drop out – imagine you are trying to hold a tennis ball between your knees

2) Wall Squats

Purpose: One of the best leg exercises for strengthening the quadriceps. A little twist on normal squats – doing them against the wall reduces the pressure going through the knee compared to conventional squats whilst still increasing the strength

Starting Position: Stand with your back against a wall, feet about 6 inches from the wall, knees apart, toes pointing forward

Action: Slide down the wall, allowing your knees to bend.  Hold for a few seconds and then push back up

Repetitions: Repeat 10-25x, 2x daily

Progression: 1) Increase the depth of the dip (up to 90°)
2) Hold the bent knee position for longer (aiming for 10secs)

Note: As you squat, don’t let your knees come too far in or out - Keep your knee in line with your second toe so you can always see your big toe past the inside of your knee

3) The Clam

Purpose: One of the best leg exercises for strengthening the buttock muscles. Almost everyone I've seen with knee pain has weak glutes. The glutes help support the knee and make sure the forces are evenly spread throughout the joint.

Starting position: Lie on your side with your hip and knees bent approx 90°, feet together

Action: Keeping your feet together, lift the top knee up as high as you can. Hold for 3 seconds and slowly lower

Repetition: Repeat 10-25x on each side, 2x daily

Note: Do not let your top hip roll backwards

4) Step Ups

Purpose: Strengthen the quadriceps and improve knee control/stability

Starting Position: Stand facing the bottom of the stairs/single step and put the leg you want to strengthen up on the step. Hold onto the wall/rail for support if required

Action: Slowly, step your other leg up onto the step and then lower it back down to the floor.

Repetition: Repeat 10-30 times, 2x daily

Progression: 1) Don’t hold onto anything
2) the slower you do the exercise, the harder it will work your knee muscles

Note: 1) Make sure you can see your big toe at all times – keep your kneecap in line with your second toe, don’t let the knee fall inwards
2) If you don’t have any steps at home, be creative e.g. large book

5) Side Step Downs

Purpose: Strengthen the quadriceps, improve balance, improve knee stability

Starting Position: Stand sideways on top of a step. Hold the wall/rail for support

Action: Slowly lower your good leg down to the floor and then bring it back up (keeping your other foot up on the step throughout)

Repetition: Repeat 5-20x, 2x daily

Progression: Stand facing forwards and step down instead of sideways, lightly touching the good leg to the floor

Note: 1) You are aiming to do this in a slow, controlled fashion
2) Don’t let the knee twist inwards

6) Solo Heel Raises

Purpose: Strengthen the calf muscles to help support the knee

Starting position: Stand on one leg holding onto something stable for balance.

Action: Push up onto your tiptoes so your heel is up of the ground as high as you can. Hold for 3-5 secs and slowly lower

Repetition: Repeat 10-30 times, 2x daily

Target: When you can do 30 repetitions on a single leg, that is a good sign you have good strength in your calf muscles

Best Leg Exercises For Balance

Good balance/proprioception is really important to prevent knee injuries. As a quick test to see whether you would benefit from this exercise try standing on one leg with your eyes closed. If you can’t do it for 1 minute, you would benefit from this exercise. This is one of the most simple but best leg exercises to help your body learn the subtle adjustments needed for good balance.

Balance exercises are an important part of the best leg exercises programm

1) Single Leg Standing

Starting position: Standing

Action: Lift up your good leg and stand on one leg for as long as you can

Repetition: Spend 5 minutes doing this 2x daily

Progression: 1) Close your eyes and perform the exercise as above
2) Open eyes and throw and catch a ball
3) Slowly bend and straighten your knee a small amount while doing the exercise

Best Leg Stretches

Tight muscles are a common cause of knee pain. If the muscles are tight, it changes the way the knee moves and alters how the forces are distributed through the knee.

Here you will find the best leg exercises for stretching the quads and hamstrings as these are the most common muscles to be tight. Visit the knee stretches section for a quick test to see if your muscles are tight and you would benefit from stretches, or for different ways of stretching these muscles. You will also find stretches for the glutes, ITB and calf muscles there.

1) Lying Quads Stretch

Purpose: Best leg exercises to stretch the quads muscles. Quads tightness is a common feature in knee problems

When to do: Before and after exercise, most knee problems

Starting Position: Lie flat down on your tummy

One of the best leg exercises for stretching the quad

Action: Bring your heel towards your bottom pulling at the ankle until you feel a stretch in the front of your thigh – if you can’t reach your ankle put a towel or belt around your foot and pull that. Hold for 30 secs.

Repetition: Repeat 3 times, 2x daily, or before and after exercise

Progression: 1) Prop yourself up on your elbows and carry out the exercise as described above
2) Place a pillow/rolled up towel under your knee and carryout the exercise as described above. Combine with progression 1 to stretch further

2) Standing Hamstring Stretch

Purpose: Best leg exercises to stretch the hamstring muscles

When to do: Before and after exercise, most knee problems

Hamstring stretches can really help reduce knee pai

Starting position: Find a stool or object that is about 50cms / 1 ½ foot high. Leave one foot on the floor and rest the other foot on the stool with the knee slightly bent (about 15°)

Action: Lean forwards and down, keeping your back straight, until you feel a stretch in the middle of the back of the thigh. Hold for 30 secs

Repetition: Repeat 3 times, 2x daily, or before and after exercise

Tips: 1) You want to feel the stretch in the middle of the thigh rather than behind the knee – bending the knee slightly helps to achieve this
2) If you do not feel much of a stretch, lean slightly to the side of the leg being stretched as well as forwards and you may feel more of a stretch
