The 9 best cardio workouts to shake up your routine

Running sucks — or at least it seems like it when you’re just starting out. For a lot of people, learning to run, bike, swim, or one of countless other forms of aerobic activity like HIIT workouts is an exercise in discomfort. But before you head out the door in your brand-new workout gear, intent on suffering for some vague sense of “fitness,” let an expert weigh in. “You have to have a plan,” said Mecayla Froerer, Head of Fitness Programming at iFit.

Not familiar with iFit? You likely are familiar with its hardware-based dependents, including NordicTrack, ProForm, and Freemotion, which, along with its stand-alone app, stream interactive workouts across a host of disciplines. Some of the modalities in which Froerer’s trainers concoct plans for every need and all its related machines are running, biking, rowing, and HIIT classes. It’s no surprise, then, that Froerer, a swimmer by training and a runner of late, appreciates moving broadly across disciplines.

“There are quite a few benefits to using your body in different ranges of motion, different planes of motion,” she said. Training across cardio methods can help your mind stay fresh while your muscles develop balance. Tight hip flexors from cycling? Expand them by running. Lost flexibility and core strength running? Pull a few hundred meters on the rower and see what it does for your back. “Working those other muscles that you may not be accessing very often is critical to being well-rounded,” she told us. The best part is that all of her cardio workouts are incredibly fast, allowing you to get it in and get on with your day.

Running: Strength intervals

From Chariots of Fire to Forrest Gump, running has long been lauded for its simplicity in execution. Yeah, some of the best running gear can make it more comfortable, but really, the only thing you need is a good pair of shoes. When you’re ready for more than just a comfortable jog, try this one with intensity on a 1-to-10 feel.

Targeted muscles: Lower body, core, aerobic system, and some upper body

Equipment needed: None

Execution: After a five-minute light jog as a warm-up:

1. “7” intensity, four minutes
2. Two-minute easy recovery

Repeat for three total rounds. Cool down with a light five-minute jog to finish.

Walking: Speed walk

Sure, everyone walks. But ask any city dweller, and they will tell you that hoofing it 10 blocks around uptown is no small task. If you’re ambivalent about running or just not feeling like you’re ready, walking can be a great alternative or transition

Targeted muscles: Lower body, core, aerobic system, and some upper body

Equipment needed: None

Equipment name:

ProForm Carbon T10

Execution: After an easy three-minute warm-up walk, then:

1. “7” intensity, one minute
2. One-minute easy-walk recovery
3. “7” intensity, 90 seconds
4. One-minute easy-walk recovery
5. “7” intensity, two minutes
6. One-minute easy-walk recovery

Repeat for two rounds, then cool down with an easy walk for three minutes.

Trekking or elliptical

For those who want to avoid the pounding of running or an alternative to it, an elliptical is a great option. While its movement is similar, the circular pattern eliminates hard footfalls.

Targeted muscles: Lower body, core, aerobic system, and upper body

Equipment needed: Elliptical machine

Execution: After an easy three-minute warm-up:

1. “6” intensity, two minutes, moderate-high resistance
2. One-minute easy recovery, light resistance

Repeat three times, then:

1. “7” intensity, one minute, moderate-high resistance
2. Thirty-second easy recovery, light resistance

Repeat three times, then:

1. “7” intensity, 30 seconds,
2. Fifteen-second recovery

Repeat three times, then cool down for three minutes.

Cycling

Whether on a protected loop, open road, or a studio bike, cycling develops your aerobic system while avoiding repetitive pounding. Your calves will be chiseled from marble, your quads will ripple, and your belly will recede.

Targeted muscles: Lower body, core, and aerobic system 

Equipment needed: Bike of some kind 

Equipment name:

ProForm Studio Bike Pro 22

Execution: After a five-minute easy warm-up, then:

1. 30-second push, moderate resistance, at 90 to 95 revolutions per minute (RPMs)
2. 30-second recovery, light resistance, at 70-75 RPMs
3. One-minute push, moderate resistance, at 90 to 95 RPMs
4. One-minute recovery, light resistance, at 70-75 RPMs
5. Ninety-second push, moderate resistance, at 90 to 95 RPMs
6. Ninety-second recovery, light resistance, at 70-75 RPMs
7. Two-minute push, moderate resistance, at 90 to 95 RPMs
8. Two-minute recovery, light resistance, at 70-75 RPMs
9. Ninety-second push, moderate resistance, at 90 to 95 RPMs
10. Ninety-second recovery, light resistance, at 70-75 RPMs
11. One-minute push, moderate resistance, at 90 to 95 RPMs
12. One-minute recovery, light resistance, at 70-75 RPMs
13. 30-second push, moderate resistance, at 90 to 95 RPMs
14. 30-second recovery, light resistance, at 70-75 RPMs

Cool down for five minutes.

Rowing: Stroke-rate builds

Whether you’re plotting for control of a fictitious executive branch a la House of Cards or just looking for a whole-body workout, rowing has a lot of benefits. Focusing on your technique, you’ll gradually be increasing your speed, or Stroke Rate (SR), getting more intense by the minute.

Targeted muscles: Lower body, core, aerobic system, and upper body 

Equipment needed: Rowing machine or an actual boat

Execution: After a three-minute, easy pull warm-up, then:

1. One minute, 22 SR
2. One minute, 24 SR
3. One minute, 26 SR
4. One minute, 28 SR

Pull easy for one minute of recovery, then:

1. One minute, 26 SR
2. One minute, 28 SR
3. One minute, 30 SR
4. One minute, 32 SR

Pull easy for three minutes of a cool-down.

Climbing

Most beginners believe that climbing is all upper body. When done correctly, the sport recruits total musculature, from grip through abs and legs. While there are climbing machines that loosely simulate the basics, you can easily plot a route at your local gym for this suggested workout.

Targeted muscles: Full body

Equipment needed: Climbing machine, an indoor climbing wall, or your nearby crag

Execution: Either traverse on a wall as a warm up for two minutes or easily use the machine for the same time, then:

1. Push (aggressively climb), 30 seconds
2. Recover (downclimb or continue to easily move on the machine), 30 seconds
3. Push, 45 seconds
4. Recover, 45 seconds
5. Push, one minute
6. Recover, one minute
7. Push, 45 seconds
8. Recover, 45 seconds
9. Push, 30 seconds
10. Recover, 30 seconds

Repeat this set twice, then cool down by traversing for one to two minutes.

Free weights

Instead of scrolling through your Instagram between sets, reduce your recovery and think of your muscle-building session as aerobic as well. This bodyweight- and free-weight-designed workout will leave you panting after and sore the following day.

Targeted muscles: Upper body, lower body, core, and aerobic system 

Equipment needed: Dumbbells, kettlebells, and fitness mirror (optional)

Execution:

1. Dumbbell kickbacks, 12
2. Dumbbell bicep curls, 12

3. Scissor kicks, 30 seconds
4. Mountain climbers, 30 seconds
5. Rest, 30 seconds

Repeat this circuit three times.

Cables

Similar to a rower, the specialized cable machine at your local gym can give a hell of a workout that hits differently than your average jog. Recruiting the core and lower body even as your upper body delivers the power, it’s an easy way to shake up a stale cardio routine.

Can you lose weight by doing cardio?

You can lose weight by doing cardio, but it’s not the whole story. While cardio certainly plays a role in weight loss, it’s not the only piece of the puzzle and may not be the most effective approach on its own. Here’s what you need to know.

Pros of cardio for weight loss

• Burns calories: This is the main benefit. Cardio activities like running, swimming, or cycling raise your heart rate and make your body work harder, leading to calorie expenditure.
• Improved fitness: Regular cardio strengthens your heart and lungs, improving your overall fitness level and helping you sustain longer workouts.
• Boosted metabolism: Some forms of cardio, particularly HIIT workouts, can temporarily increase your metabolic rate, meaning you burn more calories even at rest.

Cons of relying solely on cardio for weight loss

• Muscle loss: Overdoing cardio can lead to muscle loss, which can actually slow down your metabolism and make it harder to lose weight in the long run.
• Increased appetite: Intense cardio can trigger hunger hormones, making you feel hungrier and potentially leading to overeating.
• Sustainability: Cardio-heavy routines can be demanding and repetitive, making them harder to stick with over time.

Cardio and strength training

Combine cardio with strength training so you can build muscle mass to help you burn more calories at rest and maintain a healthy metabolism. Aim for at least two to three strength training sessions per week. Also, you want to focus on diet, as your calorie intake plays a crucial role in weight loss. Create a sustainable calorie deficit by eating healthy, nutritious foods.
