Low Impact Cardio: The Workout That Saved My Knees (And My Sanity)

Did you know that nearly 54 million adults in the U.S. suffer from some form of arthritis? I was shocked when I first read that. And honestly, it made me feel a lot less alone when my doctor told me I needed to dial back my high-intensity workouts and switch to something gentler. That’s when low impact cardio became my best friend.

At first, I was pretty bummed. I mean, I loved my boot camp classes! But after a few weeks of low impact training, I realized I wasn’t missing out — I was actually leveling up.

What Is Low Impact Cardio, Exactly?

Low impact cardio is any aerobic exercise where at least one foot stays on the ground at all times. Think walking, swimming, cycling, or using an elliptical machine. It gets your heart rate up without putting too much stress on your joints, bones, and connective tissue.

It’s not the same as low intensity, though — that’s a mistake I made early on. You can absolutely push yourself hard during a low impact workout. The “low impact” part just refers to how much force is hitting your body, not how hard you’re working.

Why Low Impact Cardio Is Worth Your Time

Here’s the thing — low impact cardio workouts are seriously underrated. A lot of people think they need to be jumping around and sweating buckets to get a real workout in. That’s just not true. Research from the American Heart Association shows that moderate-intensity aerobic activity — which includes low impact exercises — can significantly reduce the risk of heart disease and stroke.

Plus, low impact cardio is great for burning calories, improving cardiovascular endurance, and even boosting your mood. I noticed a big difference in my energy levels after just two weeks. Honestly, I kind of wished I had started sooner.

My Favorite Low Impact Cardio Exercises

Over the years, I’ve tried a bunch of different options. Here are some of my go-to low impact cardio exercises that I keep coming back to:

• Walking: Simple, free, and incredibly effective. A brisk 30-minute walk can do wonders for your cardiovascular health.
• Swimming: Probably the most joint-friendly workout out there. The water supports your body weight, making it perfect for people with knee or back pain.
• Cycling (indoor or outdoor): I personally love a good spin session. It’s low impact but can still be super challenging if you crank up the resistance.
• Elliptical training: A solid gym option that mimics running without the pounding. Great for maintaining aerobic fitness.
• Water aerobics: Don’t sleep on this one! It’s not just for seniors — water aerobics is a full-body workout that builds strength and endurance at the same time.
• Yoga flows and Pilates cardio: These blend low impact movement with flexibility and core training. Two birds, one stone.

How to Get Started Without Overdoing It

One of the biggest mistakes I see people make — and yeah, I made this one too — is going too hard too fast. Just because it’s low impact doesn’t mean your body isn’t adapting. Start slow and build up gradually.

A good beginner routine might look like three 20-minute sessions per week. From there, you can add time or frequency as your fitness improves. The Mayo Clinic recommends aiming for at least 150 minutes of moderate aerobic activity per week — and low impact cardio counts completely toward that goal.

Also, don’t forget to warm up. I skipped that step once and pulled a muscle on the elliptical. Learn from my mistakes, people!

Your Next Step Starts Here

Low impact cardio is one of those things that works for almost everyone — beginners, seniors, people recovering from injuries, or anyone just looking to move more without wrecking their body. It’s sustainable, effective, and honestly kind of fun once you find the exercises you actually enjoy.

The key is to listen to your body, stay consistent, and don’t be afraid to mix things up. What works for me might not be your jam — and that’s totally fine. Just keep moving!
