The Best Cardio Exercises for Weight Loss, Strength, and Stamina
To many people looking to lose weight, cardio exercise means running… and that’s it. So if you don’t like rapidly planting one foot in front of the other for miles at a stretch, chances are you don’t do it. Or you give it half effort on the rare occasion you do lace up your sneakers.
But there are plenty of other ways to get your cardio on, most of which can help you boost heart health, build muscle and strength, and reach or maintain your goal weight — it all depends on how you do them. Following is everything you need to know about cardio exercises for weight loss, strength, and endurance.
What Is Cardio Exercise?
Although we think of “cardio” as activities like running, cycling, and swimming, cardiorespiratory exercise is anything that elevates the heart rate and challenges the body to deliver oxygen to working muscles.
Anaerobic vs. Aerobic Activity
Two more terms that get thrown around along with cardio are “aerobic” and “anaerobic.” These designations refer to how much oxygen is used to produce energy for the task at hand. While each energy system is always in use to some extent, the intensity of activity determines which form of fuel is utilized more.
Aerobic exercise relies primarily on oxygen to produce energy, and is performed at low or moderate intensity for an extended period of time (more than 2 minutes or so) due to the length of time necessary to produce that energy.
Examples: marathon running, swimming, road cycling, etc.
Anaerobic exercise, on the other hand, does not emphasize oxygen as its main source of energy, relying more on ready glycogen and phosphocreatine. Anaerobic activity is performed in bursts (up to 2 minutes or so) at high intensities.
Example: sprinting, weightlifting, and high-intensity intervals
The anaerobic threshold — at which you cross over from aerobic into anaerobic activity — varies from person to person, but generally starts around 80 percent of your max heart rate. Here’s a formula that can help you determine your max heart rate.
220 minus your age = your age-adjusted max HR
For example, if you’re 30 years old, your age-adjusted maximum heart rate is 220 minus 30 years = 190 bpm. From there, calculate appropriate percentages of that number to determine your target zones.
In this case, 80 percent (the anaerobic threshold) is about 152 beats per minute. You can use a heart rate monitor to track your BPMs during exercise to make sure you’re adequately challenging yourself relative to your objectives.
The Talk Test
If you prefer an even simpler way of tracking your effort, there’s the talk test. Can you carry on a conversation? If not, you’re doing anaerobic work.
Your body needs to expire (exhale) carbon dioxide to metabolize glycogen, So the pace of your breathing picks up and you lose the ability to talk.
Another way to gauge the intensity of activity is the rate of perceived exertion (RPE) — basically, how hard you feel you’re working. The RPE scale runs from six to 20, which roughly corresponds with your heart rate divided by 10.
At rest, your RPE is six. Light activity lands you at 11, hard work gets you up to 15, and all-out maximal exertion takes you up to 20.
Benefits of Cardio Exercise
Like all exercise, cardiorespiratory workouts offer a slew of perks. “Cardio improves circulation of blood and oxygen, allows you to exert yourself longer without being fatigued, helps make the heart more efficient, burns off calories, helps you sleep, gives you more energy, and reduces stress,” says Michele Olson, Ph.D., professor of sport science at Huntingdon College.
Cardio can even help you become stronger. “Enhancing aerobic capacity can improve blood, oxygen, and nutrient flow to working muscles, and help with recovery between sets of resistance-training exercises.
Cardio for Weight Loss
Of course, chief among the benefits of cardio for many people is weight loss. Research has long found that both endurance and interval training improve body composition, decrease waist circumference, and lead to similar amounts of weight loss.
However, high-intensity exercise has been found to trump aerobic exercise at decreasing body fat, owing primarily to the afterburn effect of excess post-exercise oxygen consumption (EPOC). Where steady-state (low to moderate intensity) activity may burn more calories during its typically longer durations, high-intensity exercise keeps your metabolism elevated long after a workout, in some cases up to 72 hours. That means more calories burned overall.
And since interval training takes less time to get the same results, many prefer it. In a small study published in 2016, a group of sedentary men was split into two groups who exercised three times a week for 3 months: one group did moderate-intensity cycling for 45 minutes, while the other alternated three 20-second cycle sprints with low-intensity pedaling for 10 minutes.
At the end of the experiment, both groups lost about 2 percent of their body fat. But the second group worked for one-fifth as much time as the first. “With HIIT, you are utilizing all your systems efficiently — you’re getting the biggest bang for your buck in the shortest time
How Much Cardio Should You Do?
The American College of Sports Medicine recommends adults get at least 2 1/2 hours of moderate-intensity cardio, or 60 minutes of high-intensity cardio, each week for general fitness. That works out to 30 minutes 5 days a week, or 20 minutes 3 days a week, respectively.
But you can split up that time within the day, too. For instance, that can be 15 minutes of jump rope in the morning and 15 minutes of soccer with your kids in the afternoon. Just be sure to push yourself (and pay attention to your heart rate) if you’re aiming for more vigorous cardio.
If you’re newer to cardio, set a small, realistic goal, such as 15 minutes, three times a week.
From there, add 5 to 10 percent more cardio each week. So, 15 minutes becomes 17 minutes, and then 20 minutes, etc. You can add 5 to 10 percent more mileage if you prefer to use distance as your measurement.
It’s OK to do some form of cardio every day, as long as you’re not doing super intense workouts daily. If you put in a hard day, make the one that follows an active recovery day with a walk or perhaps yoga.
Types of Cardio Training
The method by which you perform cardio is as important to your goals as the exercises themselves. The following strategies alter variables like tempo, rest, and even activity.
This is steady-state cardio, wherein you maintain roughly the same pace throughout a workout. You can do this with any of the cardio exercises listed below. You’ll burn calories and train your body to consume oxygen more efficiently, but you won’t build much strength, and you’re likely to lose some muscle. Best for: Muscular endurance, cardiovascular endurance
As mentioned above, alternating between periods of high-intensity bursts (such as sprinting) and lower-intensity rest or recovery (such as jogging or walking) will burn more calories in less time. It also generally burns more fat overall, improves anaerobic capacity, and helps your body recover quicker. Best for: Muscular development, cardiorespiratory capacity, fat loss
This type of total-body workout involves performing a number of different exercises in succession (a circuit) with minimal rest in between. It typically involves combining cardio and strength training, though Olson notes it isn’t optimal for either. For weight loss, however, it can be quite effective. Alternate between exercises such as squat lunges, burpees, medicine ball passes, and mountain climbers for 30 to 60 seconds each, then rest a minute between rounds. Best for: Muscular development, muscular endurance, cardiorespiratory capacity, fat loss
Easy to do most anywhere and fairly cheap, running offers a slew of benefits, like strengthening bones and enhancing joint health. However, “the repetitive impact can cause lower-extremity overuse injuries if you don’t vary it with other forms of exercise.
Easier on your joints than running, biking challenges your body to effectively deliver oxygen to muscles, which offers a greater likelihood for growth.
Another great option if you have joint issues, swimming is a total-body workout.
Crew teams are in top shape because rowing is a great total-body cardio and muscular workout. It’s also low-impact, sparing shock to joints.
This kind of exercise most often refers to jump training, and can burn many calories as you increase your explosive power. Naturally, though, good form is a must for this high-impact activity, or you increase the risk of injury.
Who says cardio can’t be fun? Whether you prefer moving to pop music, country music, or something in between, dancing is a great way to improve aerobic — and even anaerobic — capacity.
Cheap, portable, and easy to do pretty much anywhere, jumping rope builds aerobic and anaerobic endurance, and may help improve coordination, balance, and bone mineral density, research shows. It’s best to wear the right shoes.
Consistent hiking for 2 to 4 hours at a time uses the aerobic energy system, which can help increase the utilization of fat for energy. Hiking is also easier on your joints than running, plus you’re spending time in nature, which has been shown to improve mood among other benefits.
Old-school bodyweight exercises like squats and pushups are a great way to get your heart pumping and build muscular endurance. The more muscles used, the more oxygen required, and the more calories burned. Try jumping jacks, high knees, ice skaters, mountain climbers, and burpees.
Games like softball, basketball, and soccer offer more than friendly competition. Each sport has different benefits for your body, from the fuel system you use to skills required of your body and mind. The movements required in different sports help teach coordination while keeping cardio fun and interactive.
Cardio Is Way More Than Running
You can get the benefits of cardio in many more ways than simply running. Whether you swim, dance, or do VargusFitness workouts , be sure to do more than one thing.
Your body is capable of a lot of things. For general health and fitness, encompass all of it,. Do endurance as well as interval workouts, in all forms of cardio, to lose weight, improve overall fitness, and reduce your risk of injury.
