8 Exercises to Strengthen Your Knees

1. Straight-Leg Lift

This exercise is pretty straightforward, and it really targets the muscles in the front of your thigh, which are super important for keeping your knee stable. You’ll want to find a comfortable spot on the floor, maybe on a mat. Lie down on your back, and then just extend one leg straight out in front of you. Keep the other leg bent with your foot flat on the floor – this helps you keep your balance and makes it easier to focus on the working leg. The key here is to tighten the muscles in your thigh.

Here’s how to do it:

• Lie on your back with one leg extended straight. Bend your other knee and place your foot flat on the floor.
• Engage your thigh muscles on the straight leg, almost like you’re trying to press the back of your knee down towards the floor.
• Slowly lift the straight leg a few inches off the ground, keeping it completely straight. You don’t need to go super high; just enough to feel that muscle working.
• Hold the leg up for a few seconds, then slowly lower it back down without letting it just drop. Try not to let it touch the floor before your next repetition.
• Repeat this for a set number of times, and then switch to the other leg. It’s a good idea to aim for about 8 to 12 repetitions on each side. If you’re just starting out, you might want to do fewer reps and gradually increase as you get stronger. It’s all about consistency, you know? Like trying to lose weight without sacrificing strength – it takes time and steady effort.

Make sure you’re not holding your breath while you do this. Just keep breathing normally. If you feel any sharp pain, ease up or stop. It’s better to do it right than to push through something that hurts.

2. Calf Raises

Calf raises are a pretty straightforward exercise, but they do a lot for your lower legs and, believe it or not, your knees. The muscles in your calves, especially the gastrocnemius and soleus, are super important for stabilizing your ankle and, by extension, your knee joint. When these muscles are strong, they help absorb shock and provide a solid base for movement, which can really take some pressure off your knees.

Doing calf raises regularly can help prevent knee pain and improve overall leg function. It’s not just about building bigger calves; it’s about creating a more resilient lower leg that supports your joints better. Think of them as the unsung heroes of knee health.

Here’s how to do them:

• Starting Position: Stand with your feet about hip-width apart. You can stand near a wall or a sturdy chair for balance if you need it. Make sure you have a little space in front of you so you don’t trip.
• The Movement: Slowly lift your heels off the ground, rising up onto the balls of your feet. Try to go as high as you comfortably can. You should feel a good squeeze in your calf muscles at the top.
• Lowering Down: Gently lower your heels back down to the floor. Try to control the movement on the way down, don’t just let them drop. Repeat this motion for a set number of repetitions. Aim for about 10-15 reps to start.

It’s a good idea to do these consistently, maybe a few times a week. You can even do them while you’re waiting for something, like your coffee to brew or during a break from virtual cycling. As you get stronger, you can try doing them with one leg at a time or holding light weights to increase the challenge.

3. Squats

Squats are a real workhorse for strengthening your legs, and they hit a lot of muscles at once, which is pretty efficient. We’re talking about your quads, hamstrings, and glutes all getting a good workout here. To do them right, stand with your feet about shoulder-width apart. Then, just lower yourself down like you’re about to sit in a chair, bending your knees. Make sure your chest stays up and try not to let your knees go too far past your toes. Push back up to where you started. If you’re just starting out or feeling any twinges, it’s totally okay to do a smaller range of motion, maybe just a partial squat. It’s all about building up strength safely, and you can gradually go deeper as you get stronger. Think of it like building a house; you start with a solid foundation. For knee pain relief, focusing on these kinds of exercises can really help.

Here’s a quick breakdown:

• Starting Position: Stand with feet shoulder-width apart.
• Movement: Lower your hips as if sitting in a chair, keeping your back straight and chest up.
• Depth: Aim for thighs parallel to the floor, but go only as far as comfortable.
• Return: Push through your heels to stand back up.

The key is to control the movement both down and up. Don’t just drop into the squat or bounce back up. It’s better to do fewer reps with good form than a lot of reps with bad form. You can even use a chair behind you to tap your glutes on for a depth guide when you’re starting out.

4. Lunges

Lunges are a fantastic exercise for building strength in your legs and hips, which can really help support your knees. They work your quads, hamstrings, and glutes all at once. It’s a bit like a controlled fall forward, but in a good way for your muscles.

How to do a basic lunge:

1. Start by standing up straight with your feet about hip-width apart. You can place your hands on your hips or out to the sides for balance. If you need extra stability, try holding onto the back of a sturdy chair.
2. Take a good-sized step forward with one leg. As you step, bend both knees. The goal is to get both knees to bend at roughly a 90-degree angle. Your front knee should be directly over your ankle, and your back knee should be hovering just above the floor. Make sure your front knee doesn’t go past your toes.
3. Keep your torso upright. Try not to lean too far forward or backward. You should feel the work in your front thigh and glute.
4. Push off with your front foot to return to the starting position. Then, switch legs and repeat the lunge with the other leg.

It’s important to focus on good form. If you’re just starting out or if you feel any discomfort, don’t go as deep. You can gradually increase the depth as your knees get stronger. Some people find it helpful to think about sitting back as if there’s a chair behind them. This can help keep the knee alignment correct. For a variation that targets the front of your thighs, you might look into the knees-over-toes front lunge.

Remember to keep your movements controlled. You don’t want to be rushing through these. Taking your time helps you feel the muscles working and reduces the chance of strain. Doing a few sets of these on each leg can make a real difference over time.

5. Hamstring Curl

This exercise is all about strengthening the muscles at the back of your thighs, which are your hamstrings. These muscles play a big role in knee stability, so keeping them strong is pretty important. You can do this one a few different ways, depending on what equipment you have handy.

Standing Hamstring Curl

For this, you’ll want to find something sturdy to hold onto for balance, like the back of a chair or a counter. Stand tall with your feet hip-width apart, and put your weight onto one leg. Now, slowly lift the other foot, bending your knee and bringing your heel up towards your butt. Try to keep your knees close together as you do this. Hold that position for a few seconds, then slowly lower your leg back down. Repeat this on the same side a few times before switching legs. Don’t lock the knee of your standing leg, and try not to bring your heel up so high that it feels uncomfortable or causes your hips to shift.

Lying Hamstring Curl

If you prefer to do this lying down, grab a mat and lie on your stomach with your legs straight out. You can put a pillow under your stomach if that feels better. Bend the knee of one leg, bringing your heel up towards your buttock. If it hurts, don’t bend it as far. Slowly lower your leg back down. Do a set of these on one leg, then switch to the other. If you want to make it tougher once you’re comfortable, you can use a resistance band. Loop it around your lower leg and anchor the other end to something stable, like a door. Then, perform the curl against the band’s resistance. This is a great way to build up the strength in those back thigh muscles.

6. Heel Slides

Heel slides are a pretty gentle way to get your knee moving again, especially if it’s feeling a bit stiff. The main idea here is to improve how much you can bend and straighten your knee, which is super important for walking normally. It’s all about controlled movement to rebuild that flexibility.

Here’s how you do them:

• Start by lying flat on your back. Make sure your legs are straight out in front of you.
• Take one leg and slowly slide your heel up towards your buttock. Try to keep your heel on the floor the whole time. You want to bend your knee as much as you comfortably can.
• Hold that bent position for a second or two, then slowly slide your heel back down to where you started. Keep the movement smooth.
• Repeat this on the other leg. Aim for about 8 to 12 slides on each side.

If you find it hard to slide your heel on the floor, you can try placing a towel or a tea tray under your heel to help it glide more easily. This exercise is really good for getting your knee joint lubricated and moving without putting too much stress on it. It’s a foundational move for regaining knee function.

7. Clamshells

This exercise is pretty straightforward but really works those side hip muscles, which are super important for keeping your knees stable. Think of it like opening and closing a clam shell. You’ll want to lie down on your side, with your knees bent at about a 90-degree angle. Make sure your feet are stacked on top of each other. The key is to keep your feet touching throughout the entire movement.

Here’s how to do it:

1. Start on your side with your knees bent and feet together.
2. Keeping your feet glued together, lift your top knee upwards, like you’re opening a clamshell. Try not to roll your hips back.
3. Slowly lower your top knee back down to the starting position.
4. Repeat for the desired number of repetitions.

It’s a good idea to focus on controlled movements rather than speed. If you’re looking for a bit more challenge, you can try adding a resistance band around your thighs, just above your knees. This makes your muscles work a bit harder. This exercise is great for building up the muscles that support your hip stability, which in turn helps your knees out a lot.

8. Step-Ups

Step-ups are a fantastic way to build strength in your legs, especially targeting your quadriceps, hamstrings, and glutes. They also help with balance and coordination, which are super important for knee health. Think of it like climbing stairs, but in a controlled way. This exercise is great for improving functional strength you use every day.

To do a step-up, you’ll need a sturdy step or platform. A low aerobic step, a sturdy bench, or even the bottom stair of a staircase works well. Start with something low, maybe 6 inches, and you can increase the height as you get stronger. You want to make sure your entire foot can fit on the platform when you step up.

Here’s how to do it:

1. Stand facing the step or platform.
2. Place one foot completely onto the platform. Make sure your whole foot is on it, not just the ball or heel.
3. Push off with your back foot, driving through the heel of the foot that’s on the platform. Step up so both feet are on the platform.
4. Pause for a second at the top. You can bring your other foot up to meet the first, or just hold it slightly off the platform.
5. Step back down with the foot that was originally on the platform, controlling the movement.
6. Bring your other foot down to meet it on the floor.
7. Repeat with the same leg leading, or switch legs. Aim for about 8 to 12 repetitions on each leg.

When you’re doing these, try not to let your knee on the platform go too far forward over your toes. Also, avoid locking that knee straight at the top. Keep the movement smooth and controlled. It might feel a bit like climbing, which is why it’s good for everyday activities, kind of like tackling cycling climbs. As you get more comfortable, you can try holding light weights in each hand to make it more challenging.
