Low-Impact Cardio at Home: Best Exercises for Bad Knees and Joints


Here’s something I wish someone had told me years ago: you do not need to jump, sprint, or pound your joints into the ground to get a serious cardio workout at home. Not even close.

If you’ve ever stepped away from a workout with aching knees, throbbing ankles, or hips that feel ten years older than the rest of you, you know the frustration. You want to stay active and keep your heart healthy, but every “beginner-friendly” workout online still has burpees and jump squats sprinkled in like confetti.

I train at home every single day, and a good chunk of my weekly routine is low-impact cardio at home. It keeps my heart rate up, my joints happy, and my consistency rock-solid. Whether you’re dealing with bad knees, recovering from an injury, just starting out, or simply prefer training that doesn’t rattle your skeleton, this guide has you covered.

Let’s get into the 12 best low-impact cardio exercises you can do right in your living room - plus a ready-to-use workout, knee protection tips, and everything else you need to make this stick.

Key Takeaways

  • Low-impact does not mean low-effort. You can absolutely build cardiovascular fitness and burn calories without jumping or high-impact movements.
  • All 12 exercises below require zero equipment and can be done in a small space at home. Optional equipment suggestions are included if you want to progress.
  • Every exercise includes a modification so you can scale the movement to your current fitness level or work around joint limitations.
  • Consistency beats intensity. A gentle cardio workout you do five times a week will always outperform a brutal session you dread and skip.
  • Listen to your body. Sharp or worsening pain during any movement is a signal to stop - not push through.

What Is Low-Impact Cardio?

Low-impact cardio is any cardiovascular exercise where at least one foot stays on the ground at all times - or where you’re seated or supported. That’s really it. There’s no launching yourself into the air, no jarring landings, and far less stress on your knees, hips, and ankles.

Think of it this way: running is high-impact because both feet leave the ground and you land with 2–3 times your body weight on every step. Walking is low-impact because one foot is always planted. The exercises in this guide follow that same principle.

Low-impact cardio at home is ideal for:

  • People with knee pain, arthritis, or joint issues
  • Complete beginners building a fitness foundation
  • Anyone recovering from injury (with doctor’s clearance)
  • Older adults looking for safe, effective movement
  • Experienced exercisers on active recovery days
  • Anyone who simply prefers gentler training

There’s no gatekeeping here. Low-impact cardio is a legitimate training style - not a consolation prize for people who “can’t handle” harder workouts.

Benefits of Low-Impact Cardio

Heart Health Without the Wear and Tear

Your cardiovascular system doesn’t care whether your feet leave the ground. It responds to sustained, elevated heart rate - period. Low-impact cardio exercises raise your heart rate into that beneficial zone without the repetitive joint stress of jumping and running on hard surfaces. Research consistently shows that moderate-intensity cardio improves heart health and lowers blood pressure regardless of whether it’s high- or low-impact.

Joint-Friendly and Sustainable

The best workout program is the one you can actually stick with long-term. If high-impact exercise leaves you sore or injured every few weeks, your consistency takes a hit. Low-impact exercises for bad knees let you train frequently without accumulating joint damage. That consistency compounds into real, lasting results.

Accessible to Nearly Everyone

You don’t need a gym, special equipment, or a high baseline fitness level. Most of the exercises below can be performed in a space the size of a yoga mat. If you can stand - or even sit - you can do low-impact cardio at home.

Pairs Perfectly With Other Training

Low-impact cardio complements your strength training and daily mobility routine rather than competing with them. Use it as a warm-up, a standalone session, or a lighter-day option. Many people find that the benefits of steady-state cardio - like improved mood and better sleep - show up faster when the exercise itself doesn’t wreck you.

The 12 Best Low-Impact Cardio Exercises for Home

Each exercise includes form cues, a modification, and a suggested duration or rep count. No equipment required.

1. Marching in Place

This is the foundation of low-impact cardio at home - simple, effective, and surprisingly good at getting your heart rate up when you commit to the pace.

How to do it:

  • Stand tall with your feet hip-width apart and your core gently engaged.
  • Lift your right knee toward hip height while swinging your left arm forward naturally.
  • Lower that foot and immediately lift the left knee, swinging the right arm forward.
  • Keep your chest lifted - avoid hunching forward as you fatigue.
  • Aim for a brisk, steady pace. Think “purposeful walk,” not lazy shuffle.

Modification: If lifting your knees to hip height bothers your joints, reduce the range of motion. Even small knee lifts at a quick pace will keep your heart rate elevated.

Duration: 60 seconds, or weave it in as active recovery between harder exercises.

2. Step Touches

A staple in gentle cardio workouts at home. Step touches are smooth, rhythmic, and easy on every joint in your body.

How to do it:

  • Stand with your feet together and a slight bend in your knees.
  • Step your right foot out to the right, about shoulder-width apart.
  • Tap your left foot next to the right.
  • Immediately step your left foot to the left and tap the right foot in.
  • Swing your arms naturally with the movement - or raise them overhead for more intensity.

Modification: Keep the steps small and the pace slow if you’re just starting out. As you get comfortable, widen the steps and pick up speed.

Duration: 60 seconds.

3. Standing Knee Lifts

Similar to marching but with a deliberate pause at the top. This adds a balance challenge and engages your core more deeply.

How to do it:

  • Stand tall, feet hip-width apart. Place your hands on your hips or hold them out to the sides for balance.
  • Slowly lift your right knee up toward your chest - as high as comfortable.
  • Hold at the top for a one-count, squeezing your core.
  • Lower with control and repeat on the left side.
  • Keep your standing leg slightly bent - don’t lock out the knee.

Modification: Stand next to a wall or sturdy chair for balance support. Stability lets you focus on the actual movement instead of wobbling.

Sets: 3 sets of 10 per leg, or 45–60 seconds continuous alternating.

4. Low-Impact Jumping Jacks (No-Jump Version)

All the arm and leg movement of a jumping jack, none of the impact. This one tends to surprise people with how quickly it gets the heart pumping.

How to do it:

  • Stand with feet together, arms at your sides.
  • Step your right foot out to the side while simultaneously raising both arms overhead.
  • Step it back in and lower your arms.
  • Step your left foot out to the side and raise your arms again.
  • Keep alternating at a brisk pace. The goal is smooth, continuous movement.

Modification: If overhead arm raises bother your shoulders, bring them to shoulder height only. You can also do both sides simultaneously (step-out, step-in) at a slower pace.

Duration: 45–60 seconds.

5. Swimming Arms

A standing exercise that targets your upper body and back while keeping your heart rate up. It also helps counteract the forward-hunching posture most of us develop from sitting.

How to do it:

  • Stand with your feet hip-width apart and a slight bend in your knees.
  • Extend both arms straight out in front of you at shoulder height.
  • Sweep both arms wide and back in a big circular motion, squeezing your shoulder blades together at the back.
  • Bring them forward again and repeat in a continuous swimming motion.
  • Maintain a steady breathing rhythm - exhale as your arms sweep back, inhale as they come forward.

Modification: Reduce the range of motion or slow the tempo. You can also perform this seated in a chair.

Duration: 45 seconds. Rest, then repeat for 2–3 rounds.

6. Seated Leg Extensions

Perfect for days when standing exercise isn’t in the cards. Don’t underestimate this one - at a brisk tempo, it’s genuinely effective cardio.

How to do it:

  • Sit tall on a sturdy chair with your feet flat on the floor, hip-width apart.
  • Grip the sides of the chair lightly for support.
  • Extend your right leg straight out in front of you, squeezing your quadricep at the top.
  • Lower it back down with control and immediately extend the left leg.
  • Alternate at a quick pace. Keep your back straight - don’t lean back as you extend.

Modification: If full extension causes knee discomfort, only extend partway. Partial range of motion is infinitely better than no movement at all.

Sets: 3 sets of 15 per leg.

7. Standing Side Leg Lifts

These target your hip abductors and glutes while keeping your heart rate elevated. Strong hips directly support healthy knees, making this doubly valuable if you’re dealing with knee issues.

How to do it:

  • Stand tall, feet together. Hold onto a wall or chair for balance if needed.
  • Keeping your body straight (no leaning), lift your right leg directly out to the side about 12–18 inches.
  • Pause briefly at the top, then lower with control.
  • Complete all reps on one side before switching, or alternate for a more cardio-focused tempo.
  • Keep your toes pointed forward throughout - not turned outward.

Modification: Reduce the height of the lift. Even a few inches activates the right muscles. The key is controlled motion, not swinging your leg as high as possible.

Sets: 3 sets of 12–15 per leg.

8. Glute Bridges (Cardio Tempo)

You probably know glute bridges as a strength exercise. Perform them at a faster, rhythmic tempo and they become surprisingly effective cardio.

How to do it:

  • Lie on your back with your knees bent, feet flat on the floor about hip-width apart. Arms rest at your sides.
  • Press through your heels and lift your hips toward the ceiling, squeezing your glutes at the top.
  • Lower back down until your hips just barely touch the floor, then drive right back up.
  • Maintain a steady, rhythmic pace - think “up-squeeze-down-repeat” without resting at the bottom.
  • Keep your core braced throughout and avoid overarching your lower back at the top.

Modification: Slow the pace if the quicker tempo bothers your knees or lower back. You can also place a folded towel or small pillow under your hips for extra support.

Sets: 3 sets of 20 at a brisk tempo, or 45 seconds per set.

9. Wall Push-Ups (Faster Pace)

Wall push-ups at a standard pace are a strength exercise. Pick up the tempo and you’ve got an upper-body cardio movement that’s easy on every joint while building pushing strength.

How to do it:

  • Stand 2–3 feet from a wall and place your palms flat against it at shoulder height, slightly wider than shoulder-width.
  • Bend your elbows to bring your chest toward the wall, then push back out briskly.
  • Maintain a straight line from your head through your heels - no sagging at the hips.
  • Move at a pace that elevates your heart rate while still letting you maintain good form.
  • Breathe steadily: inhale as you lower, exhale as you push away.

Modification: Move your feet closer to the wall to reduce difficulty, farther away to increase it. Find the distance that lets you maintain a quick tempo for the full set.

Sets: 3 sets of 15–20 reps at a brisk pace.

10. Heel Slides

A floor-based exercise that’s gentle on the knees while keeping your core and legs engaged. Particularly good for people recovering from knee surgery or dealing with significant joint limitations.

How to do it:

  • Lie on your back with both knees bent and feet flat on the floor.
  • Slowly slide your right heel along the floor, extending your leg straight out.
  • Pause briefly, then slide it back to the starting position.
  • Repeat on the left side.
  • Alternate continuously at a smooth, controlled pace. Wear socks on a smooth floor for easier sliding.

Modification: Only slide partway if full extension is uncomfortable. Focus on smooth, controlled motion rather than forcing range of motion.

Sets: 3 sets of 12 per leg.

11. Standing Calf Raises

Often overlooked for cardio, but at a quick tempo calf raises get your blood pumping and strengthen the muscles supporting your ankles and knees.

How to do it:

  • Stand with feet hip-width apart, lightly holding a wall or chair for balance.
  • Rise up onto your toes, lifting your heels as high as possible.
  • Squeeze your calves at the top for a brief moment.
  • Lower back down with control - don’t just drop your heels.
  • Maintain a brisk, steady rhythm. Think of it as a continuous pumping motion.

Modification: Reduce the range of motion, or perform these seated - pressing up onto your toes from a chair. Seated calf raises are easier on balance and still effective.

Sets: 3 sets of 20–25 reps.

12. Gentle Dancing / Movement Flow

Putting on music and moving freely is one of the most underrated gentle cardio workouts at home. It’s enjoyable, it gets your heart rate up, and you’re far more likely to do it consistently because it doesn’t feel like exercise.

How to do it:

  • Put on music you enjoy - something with a tempo that makes you want to move.
  • Start with simple side-to-side steps and arm swings.
  • Gradually add movement: sway your hips, roll your shoulders, reach your arms overhead.
  • There is no wrong way to do this. The only rule is to keep moving continuously.
  • Stay mindful of your footing - no sudden pivots or direction changes on a slippery surface.

Modification: This can absolutely be done seated. Arm circles, torso twists, and head rolls all count. Chair dancing is real cardio if you commit to it.

Duration: One full song (3–4 minutes), or longer if you’re feeling it.

Tips for Protecting Your Knees During Exercise

If you’re specifically doing low-impact exercises for bad knees, these guidelines will help you train safely.

Always Warm Up First

Cold muscles and stiff joints are more vulnerable to strain. Spend 3–5 minutes doing the gentlest movements from this list - slow marching, easy step touches, ankle circles - before picking up intensity.

Maintain a Slight Knee Bend

Locked-out, hyperextended knees put unnecessary stress on the joint. Keep a soft bend in your knees during all standing exercises - this keeps the surrounding muscles engaged and absorbing force instead of dumping it into the joint.

Watch Your Alignment

When your knee bends, it should track in line with your second toe - not caving inward or bowing outward. Poor alignment during repetitive movement is one of the fastest paths to knee irritation. If you notice yourself collapsing inward, slow down and reset.

Invest in a Supportive Surface

Hard floors are not your friend. A thick exercise mat makes a real difference for floor-based movements and reduces fatigue during standing exercises too.

Wear Proper Footwear (or the Right Barefoot Surface)

Supportive athletic shoes help with standing exercises on hard floors. If you prefer barefoot training, make sure you’re on a mat, carpet, or rubber flooring. Bare feet on hardwood during repetitive standing cardio is a recipe for sore joints.

Respect the Pain Signal

There’s a difference between muscle fatigue and joint distress. Muscle fatigue is normal. Joint pain that feels sharp, stabbing, or gets worse with movement is your body telling you to stop. Modify the exercise, reduce the range of motion, or switch to something else.

When to See a Doctor

Low-impact cardio at home is generally safe, but there are situations where checking in with a healthcare professional is the smart move. See a doctor before starting or continuing exercise if:

  • You experience persistent joint pain that doesn’t improve with rest and modification over 1–2 weeks.
  • You have swelling, redness, or warmth around a joint - especially the knee - after exercise.
  • A joint feels unstable, like it might “give way” during movement.
  • You’re recovering from surgery and haven’t been cleared for exercise yet.
  • You have a diagnosed condition like severe arthritis, osteoporosis, or a heart condition that may require specific exercise guidelines.
  • You experience dizziness, chest pain, or shortness of breath during gentle exercise.

This isn’t about being overly cautious - it’s about building on a safe foundation. Getting guidance from a professional can actually help you train more confidently, not less.

Recommended Equipment for Low-Impact Cardio

You don’t need any equipment for the exercises in this guide. But if you want more comfort or variety, these three items are worth considering.

Yoga / Exercise Mat

A thick, cushioned mat protects your joints during floor exercises and gives you a softer surface for standing work. Look for one at least 6mm thick for adequate cushioning.

Resistance Bands

When bodyweight exercises start feeling easy, light resistance bands let you increase intensity without increasing impact. Especially useful for side leg lifts, seated leg extensions, and glute bridges.

Mini Stepper

A mini stepper mimics stair-climbing without the impact, fits in a closet, and you can use it while watching TV or during work breaks. It’s one of the best compact cardio investments for home.

Sample 20-Minute Low-Impact Cardio Workout

Here’s a ready-to-follow routine using exercises from this guide. No equipment needed. Perform each exercise for the listed duration, then move to the next. Rest 60 seconds between rounds. Complete 2 full rounds for a 20-minute session.

Exercise Duration Notes
Marching in Place 60 sec Warm-up pace for Round 1, brisk pace for Round 2
Step Touches 60 sec Add arm raises to increase intensity
Low-Impact Jumping Jacks 45 sec Keep it smooth and continuous
Standing Knee Lifts 45 sec Alternate sides, squeeze your core at the top
Swimming Arms 45 sec Big, sweeping motions - stay upright
Standing Side Leg Lifts 60 sec 30 sec per side, or alternate continuously
Wall Push-Ups (fast pace) 45 sec Maintain a straight body line throughout
Glute Bridges (cardio tempo) 45 sec Quick, rhythmic pulses - squeeze at the top
Standing Calf Raises 45 sec Steady pumping rhythm
Gentle Dancing / Movement Flow 60 sec Cool-down pace - keep moving, loosen up

Total per round: approximately 8.5 minutes of work + 60 seconds rest = ~19 minutes for 2 full rounds.

Want more? Add a third round or increase each exercise to 60 seconds. Short on time? One round gives you a solid 9-minute session - far better than skipping it.

Frequently Asked Questions

Can low-impact cardio actually help me lose weight?

Yes. Weight loss comes down to a calorie deficit, and low-impact cardio burns meaningful calories - especially when you’re consistent. A 20-minute session can burn roughly 120–200 calories depending on your body weight and effort level. Do that five times a week and the numbers add up. More importantly, because it’s easier to stick with than high-impact alternatives, you’re far more likely to maintain the consistency that weight loss requires.

How often should I do low-impact cardio?

Most people can safely do low-impact cardio 4–6 days per week. Because it doesn’t create the same recovery demands as high-impact exercise, your body can handle more frequent sessions. Start with 3 sessions per week if you’re brand new, and build from there. On the other days, a daily mobility routine can keep you active without adding training stress.

Is low-impact cardio enough to improve my heart health?

Absolutely. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic activity per week. Low-impact cardio at a pace where you can talk but not sing falls squarely in that zone. You don’t need to be gasping for air to be doing your heart a favor.

What if even low-impact exercises hurt my knees?

First, try the modifications listed with each exercise - reducing range of motion, slowing down, or using a chair for support. If a particular movement still causes pain after adjustments, skip it and choose a different one. There are enough options here to build a full routine. If multiple exercises cause pain despite modifications, consult a doctor or physical therapist - there’s likely an underlying issue worth addressing.

Can I combine low-impact cardio with strength training?

This is actually the ideal approach. Low-impact cardio handles cardiovascular fitness and calorie burn, while strength training builds muscle and supports your joints. You can do them on separate days or combine them - for example, 10 minutes of low-impact cardio as a warm-up before a joint-friendly strength workout. The two complement each other perfectly.

About the author

I am a 31-year-old who discovered something life-changing: consistent movement completely transformed how I feel day-to-day. For years, I went through the motions without prioritizing my physical health. Then I committed to two simple habits—lifting weights regularly and hitting 10,000 steps every day. The difference has been remarkable. I'm not exaggerating when I say I feel better now than I have in my entire life.

Let's get after it together.
