Best Cardio Workouts: Comparing Running, Cycling, Rowing, and More

There's no single "best" cardio workout — the right one depends on your joints, your goals, and what you'll actually do consistently. Searches for "best cardio workouts" spike every year around the same time people start new fitness routines, and the honest answer disappoints a lot of people looking for a shortcut: the best cardio is the one you'll do three times a week for the next six months, not the one that burns the most calories on paper.

That said, the different options do have real, measurable trade-offs worth knowing before you pick one.

The short answer

• Running burns the most calories per minute for most people but has the highest impact on joints.
• Cycling and rowing burn nearly as many calories with far less joint stress, making them better options if you have knee or hip issues.
• Swimming is the lowest-impact full-body option but requires pool access and some technique.
• Jump rope is the most time-and-space-efficient — high calorie burn in a tiny footprint, but also high impact.
• The best choice is the one that matches your body, your access to equipment, and what you enjoy enough to repeat.

Comparing the main options

Activity	Calorie burn (relative)	Joint impact	Equipment/access needed	Skill required
Running	High	High	Shoes, safe surface	Low
Cycling	Moderate–high	Low	Bike (or gym bike)	Low
Rowing	High	Low	Rowing machine	Moderate
Swimming	Moderate–high	Very low	Pool	Moderate–high
Jump rope	High	High	Rope, small space	Moderate
Brisk walking	Low–moderate	Very low	None	None

Calorie burn depends heavily on your bodyweight, intensity, and how efficiently you move — these are general comparisons, not fixed numbers.

Running

Running is popular because it needs almost no equipment and translates directly to real-world fitness. It's also unforgiving on joints, especially if you increase distance or speed too quickly. If you're new to running, start with a run-walk approach and add distance gradually — most running injuries come from doing too much too soon, not from running itself being dangerous.

Cycling

Cycling — whether outdoors or on a stationary bike — delivers a strong cardiovascular workout with almost none of running's impact, since the bike supports your bodyweight. It's a good option for people managing knee or hip issues, or anyone who wants a hard session without the next-day soreness that running can cause. See gym cardio machines guide for how stationary bikes stack up against other gym cardio equipment.

Rowing

Rowing works your legs, back, and arms in one continuous motion, which is why it burns calories at a rate close to running while staying low-impact. The trade-off is technique — poor rowing form (using your arms and back before your legs) reduces the workout's effectiveness and can strain your lower back. It's worth learning the basic drive sequence (legs, then back, then arms) before going hard.

Swimming

Swimming is about as joint-friendly as cardio gets, since the water supports your entire bodyweight. It's an excellent option during injury recovery or for people with arthritis or chronic joint pain. The barrier is access and technique — swimming inefficiently burns more energy on struggling than on actual cardiovascular training, so some instruction pays off.

Jump rope

Jump rope packs a serious cardiovascular workout into a tiny space and a few minutes — it's a legitimate option for exercise snacks or quick sessions when you're short on time. But it's high-impact on the ankles, knees, and calves, so it's not the best starting point if you're carrying extra weight or coming back from a lower-body injury.

Which one is actually "best" for fat loss?

For fat loss specifically, the differences between these activities matter less than total volume and consistency. An hour of moderate cycling and an hour of moderate rowing burn similar calorie totals; the bigger variable is whether you can sustain the habit. Pick the option with the lowest barrier to entry for you — the one you don't need to talk yourself into — and build consistency first. Once that's established, see how much cardio per week to dial in volume for your specific goal.

The bottom line

Running, cycling, rowing, swimming, and jump rope all train your cardiovascular system effectively — the real differences are impact, accessibility, and how well each fits your life. Logging your cardio sessions in GymMonster alongside your strength training gives you one consistent record of everything you're doing, so you can see what you're actually sticking with over time.
