Low-impact exercise is any physical activity that minimizes stress on your joints, particularly in the knees, hips, and ankles. It raises your heart rate more gradually than high-impact options like running, but that doesn’t mean it’s easy. You can get an intense, heart-pounding workout from low-impact activities if you push the pace. The defining feature isn’t effort level; it’s how much force your body absorbs with each movement.
What Makes Exercise “Low Impact”
The distinction comes down to ground reaction forces, which is the amount of force your body absorbs when your feet (or body) make contact with a surface. When you run, your legs absorb between 1.5 and 3 times your body weight with every stride. For someone who weighs 160 pounds, that’s up to 480 pounds of force hitting your joints on each footfall. Walking produces less force but still involves repeated impact as each foot strikes the ground.
Low-impact exercises reduce or eliminate that repetitive pounding. Some do this by keeping at least one foot on the ground at all times, like walking. Others remove your body weight from the equation entirely by putting you in water, on a seat, or on a gliding track. The movements tend to be smoother and more controlled, without the jarring stop-and-start forces that come with jumping, sprinting, or quick direction changes.
Low Impact Does Not Mean Low Intensity
One of the most common misunderstandings is that low-impact exercise can’t give you a serious cardiovascular workout. That’s not true. Cycling, rowing, swimming, and elliptical machines can all drive your heart rate into vigorous zones if you increase the resistance or speed. As exercise physiologist Richard Lawton at Cleveland Clinic puts it, you can “send your heart rate through the roof” on a rowing machine or bike. The only real difference is what your joints go through.
This matters because it means low-impact exercise can meet standard fitness guidelines without compromise. The American Heart Association recommends at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes of vigorous activity. Swimming laps, cycling hills, or rowing at a fast pace all qualify. You’re not settling for a lesser workout; you’re choosing one that’s kinder to your body.
Common Types of Low-Impact Exercise
The range of low-impact options is broader than most people realize. Here are the most accessible categories:
- Swimming and water aerobics. Water’s buoyancy supports your body weight, reducing the load on every joint simultaneously. Swimming is sometimes described as “zero-impact” cardiovascular exercise because there’s virtually no pounding involved. It works your entire body while keeping stress on your joints near zero.
- Cycling. Whether on a road bike, stationary bike, or recumbent bike, cycling keeps your weight off your feet. That alone makes a significant difference for your knees, hips, and ankles. It’s one of the most commonly recommended exercises during injury recovery because it maintains both muscle strength and cardio fitness.
- Rowing. Exercising from a seated position on a rowing machine takes pressure off your lower body. Rowing also engages your legs, back, arms, and core in a single pulling motion, making it an efficient full-body workout.
- Elliptical training. Elliptical machines use a gliding motion that eliminates the moment of impact you get when your foot strikes the ground while walking or running. Your feet stay on the pedals, and the movement stays smooth throughout.
- Walking. The simplest option and often the best starting point. Walking produces far less joint stress than running and requires no equipment. It’s effective enough that hospitals recommend it immediately after surgery to reduce bone loss, counter fatigue, and prevent muscle wasting.
- Yoga and Pilates. Both emphasize controlled movements, flexibility, and balance without jumping or jarring transitions. They build core strength and stability, which supports joint health over time.
- Vertical climbing machines. These simulate a climbing motion using your arms and legs in rhythm. Despite looking intense, the design distributes force so evenly that they’re considered nearly zero-impact for your joints.
Who Benefits Most
Low-impact exercise is useful for almost anyone, but certain groups benefit particularly from the reduced joint stress.
People with arthritis often avoid exercise because they assume movement will worsen their pain. The opposite is typically true. Exercise strengthens the muscles around affected joints, reduces stiffness, fights fatigue, and helps control weight, all of which ease arthritis symptoms. The key is keeping the impact low so joints aren’t subjected to additional stress while they’re already inflamed or degraded. The Mayo Clinic specifically recommends low-impact exercise as part of arthritis management, noting that it can improve balance, mood, energy, and sleep quality alongside reducing pain.
People recovering from surgery or injury are often cleared for low-impact activity well before they can return to running or sports. After some surgical procedures, patients can begin low-impact exercises as soon as pain is controlled. After more involved surgeries like breast reconstruction, the typical timeline is about four weeks. Walking is almost universally the first exercise reintroduced because it gently rebuilds fitness without risking the healing process.
Older adults, people carrying extra weight, and anyone new to exercise also benefit from starting with low-impact options. The lower injury risk makes it easier to build a consistent habit, which matters more for long-term health than any single intense session.
Effects on Bone Health
There’s a nuance worth understanding here. Weight-bearing exercise, even low-impact varieties like walking, helps maintain bone density. In a study of postmenopausal women, both low-impact and high-impact exercise groups maintained their bone mineral density over a year of training at just 20 minutes per session, three days per week. The non-exercising group lost bone density steadily over the same period. The difference between the low-impact and high-impact groups was not statistically significant, meaning walking-level exercise was just as effective as jumping or running for preserving bone strength.
However, non-weight-bearing activities like swimming and cycling, while excellent for cardiovascular fitness and joint health, don’t stimulate bone in the same way. If maintaining bone density is a priority, mixing in some weight-bearing low-impact activity like walking or using an elliptical gives you the best of both worlds: joint protection and bone support.
How to Get Started
If you’re new to exercise or returning after time off, walking is the most forgiving entry point. Even 10-minute sessions count toward your weekly total, and you can gradually increase duration and speed as your fitness improves. The 150-minute weekly target works out to about 30 minutes on five days, a manageable goal for most people.
If you want more intensity without more impact, cycling and swimming offer the steepest jump in effort for the least joint cost. A 30-minute cycling session at moderate resistance can burn comparable calories to running, and you can scale the difficulty up or down instantly by shifting gears or adjusting pace. Rowing machines are similarly versatile, letting you control intensity through stroke rate and resistance settings.
For people who prefer classes or structure, water aerobics, yoga, and Pilates all provide guided low-impact workouts with the added motivation of a group setting. Many gyms also offer low-impact interval classes that cycle between bursts of effort and recovery, giving you the benefits of interval training without the joint stress of plyometric movements.
