How Important is Cardio For Weight Loss?

cardio and weight lossYou are well aware of the fact that you lose weight when you burn more calories irrespective of how much you eat. The best way to lose weight is to follow a combination of cardio, strength training and a healthy diet.

Cardio is one of the key components because:

  • You burn more calories at one time.
  • Getting your heart rate into your target heart rate zone means your blood is pumping, you’re breathing hard, and you’re sweating and burning calories.
  • You can easily add intensity to increase your calorie burn. With cardio, it’s easy to increase your calorie burn with small changes, for instance running or walking faster, jumping higher, climbing hills or trying new activities that your body isn’t used to.
  • It adds to your overall calorie deficit. Burning calories with exercise means you don’t have to cut as many calories from your diet.
  • You can do cardio most days of the week. With strength training, your muscles require rest to recover and grow stronger. Cardio can be done most days of the week without worrying about injury or over-training.

The Best Cardio Exercises

While you know that cardio is important for weight loss, which exercises are best and how much do you really need for weight loss?

The truth is, there really isn’t any best cardio exercise. The best activity is the one you’ll do on a regular basis. So, finding something you like is critical to reaching your weight loss goals. That said, some exercises offer more intensity than others.

  • Impact activities: Exercises that involve some impact, like walking, will usually boost your heart rate quicker than no-impact activities like swimming or cycling.
  • High impact activities: High impact, or exercises that involve running or jumping, will often burn more calories than lower impact things like walking.
  • Whole body activities: When you involve both the upper and lower body, such as an aerobic activity which is also is known as cross training, it’s often easier to get the heart rate up and burn more calories.

That doesn’t mean you shouldn’t bother with low impact exercise. Both types of activities offer opportunities to burn calories and doing both gives you a well-rounded cardiovascular endurance development.

To get an idea of just how much cardio can do for you, check out the following list of common exercises. Below is the number of calories burned for a 150-pound person in 30 minutes:

  1. Step aerobics: 340 calories
  2. Stationary bike: 238 calories
  3. Swimming: 270 calories
  4. Walking 4 mph: 170 calories
  5. Running 5 mph: 270 calories
  6. kickboxing: 400 calories

Everything from walking to kickboxing can burn a significant number of calories!

How Much Do You Need?

It’s tough to know exactly how much cardio we need for weight loss. The American College of Sports Medicine and the American Heart Association recommend about 60 minutes of moderate to vigorous intensity activity on most days of the week. But, the truth is how much cardio you need varies from person to person and depends on factors such as:

  • How many calories you eat
  • How hard you exercise
  • Metabolism, age and gender
  • Fitness levels
  • Body fat percentage and weight
  • Exercise schedule

That said, here are some tips for setting up an effective cardio program:

  1. If you’re a beginner, start with 3 days of the cardio exercise of your choice, working at a level you can handle.
  2. Add time each week to work your way up to 30 to 45 minutes of continuous exercise.
  3. As you get stronger, try interval training once a week to help boost endurance and burn more calories.
  4. Work your way up to 5 to 6 days of cardio and try to vary what you do and how hard you work.

It will help you lose weight but it is most effective when combined with strength training and a healthy, low-calorie diet and adequate rest.

How Much Do You Need To Build Muscle?

You may think you shouldn’t do cardio exercise if you’re trying to gain muscle. But, cardio isn’t just for weight loss. It also helps condition the heart and lungs and promotes health and well-being. If your goal is to gain muscle, you won’t need tons of cardio. But, doing at least three 20-minute sessions a week won’t hurt your goals and will help you reap the benefits of cardio without burning too many calories. These are some simple necessities for cardio in weight loss. After reading this, I am sure all your misconceptions about weight training and weight loss are cleared!

Cardio For Weight Loss: High Intensity vs Low Intensity

cardio for weight loss

We are well aware that Cardio is the best form of exercise to achieve any kind of weight or fat loss. But to understand the intensity required to achieve this, is still a little unclear. While researching, I kept coming back to the same question, what’s better – high-intensity or low-intensity training? There’s just way too much information trying to sway readers without considering their individual goals and needs. 

Don’t worry! We’ve put together a few things you should know about in this article. It will give you a better idea of what low-intensity and high-intensity cardio training mean and will also help you decide which one you should go for! 

Low Intensity Cardio 

This workout encompasses consistent movements anywhere between 30-60 mins. It includes walking, cycling, swimming, light jogging, etc. The intensity is approx 40-60% of your maximum heart rate (your maximum heart rate = 220 – your age). 

Benefits: 

  • Consistent movements help maintain a steady heart rate (one can talk while doing any of these exercises)
  • You use more oxygen in these kind of exercises (hence fat is used as energy source)
  • Helps reduce the risk of cardiovascular disease by promoting good blood circulation
  • Reduces hyperglycemia (elevated blood sugar levels) in people with diabetes
  • Builds muscular endurance 

Disadvantages:

  • Due to the principle of adaptation, the body quickly adapts to become more aerobically efficient. So only doing low intensity training can eventually become counterproductive to your goals, especially if one of your goals is long-term fat loss or when you hit a plateau.
  • To keep up with the body’s quick aerobic adaptation process, a person would need to continually run for longer and longer distances and durations just to burn the same amount of calories they did when they first started.

High Intensity Workouts 

These workouts include quick, intense exercise bouts and short rest periods. Ranging from 4-30 minutes max. These types of workouts include a combination of sprints, burpees, squats, jumping jacks, pushups and an endless variety of other drills using only body weight or sometimes equipment like dumbbells or kettlebells. The intensity varies from 70-90% of maximum heart rate with 60-65% max heart rate in rest periods. 

Benefits: 

  • No equipment or gym needed as it can be done anywhere (great for frequent travelers)
  • Helps build muscle mass
  • Time efficient: energy is burned more quickly and even after exercise
  • Anaerobic exercise, since there is no time for oxygen consumption, the body burns more carbs
  • Because of the oxygen debt created, the body consumes extra oxygen post workout (EPOC- excess post-exercise oxygen consumption) and hence, continues burning fat post workout as well. So it has the dual benefit of carb and fat burning.

Disadvantages:

  • The body requires a day or two post HIIT for recovery, so this form of workout cannot be done daily.
  • It is physically intense! They are also harsh on your joints due to the high impact forces created in exercises like Burpees or Squat Jumps. So, if you’re just starting your fitness journey or have weak joints, HIIT cardio may not be the best place to start.

Which One Should You Choose?

It depends on you, your current level of fitness, your preferences and goals. Low-intensity is a great place to start if you have not worked out for a long time or are recovering from an injury. But if you already have experience and want to switch things up, lose some weight quickly or finally achieve your goal of going faster or further, give intervals a try. Don’t forget to be mindful of your body. Take breaks when you need to, don’t overtrain. Your body needs to rest, heal and progress! 

We hope this article on cardio for weight loss helps you achieve your goals! To learn more, check out Healthy Reads or tune in to LIVE sessions by experts on GOQii Play.

Interval training, to put your fat on flame!

HIT

Most of us have this desirable goal of losing fat but, when asked to get acting on it, we have a fixed set of excuses ready- No time! Too tough for me! Too boring to repeat the same pattern etc…

Well, it’s time to ditch these excuses and rev up the workouts, which would consume lesser time, could be easily done, least monotonous as you can get creative and come up with your own style… and not to forget- The most effective workout to reduce the fat- Interval training it is!!

Interval training is a workout in which we alternate the bursts of high-intensity exercises with intervals of lighter activity. All that we do here is, we repeatedly challenge our body and then give it shorter breaks to recover, for a massive cardio blast. It helps burn more calories in a short period of time, as compared to a steady-state exercise.

Here’s how it works-

When we vary the intensity while working out, it leads to muscle confusion. Our body gets confused and wonders what’s happening! As a regulatory mechanism, our heart rate shoots up and it starts pumping more blood. More the blood, higher the Oxygen and to your surprise fat combustion occurs more efficiently in the presence of Oxygen.

Ever wondered why candle stops burning when we put a glass over it and block the Oxygen? That’s exactly the principle. Any burning process requires O2 which is a key to burning fat. And since interval training involves a lot of Oxygen, it’s been gaining fame in the fat loss/inch loss sector.

There are no hard and fast rules in interval training. We can have variations as we want, to make it most enjoyable and thus keep boredom at bay.

We can-

Interval walk: Walking fast for 2 minutes, then walking slowly for a minute, again fast, then slow and go on this way as long as we can.

Interval runs Alternating 2 minutes run with a 1-minute walk.

Interval swim: Alternating fast-paced swimming moves with slow-paced moves.

We can also try this with cycling, dancing, strengthening exercises (Tabata- being the most popular form of High-Intensity Interval Training) and the list can go on.

It’s quite possible to take interval training to many levels. The length and speed of each high-intensity interval solely depend upon our strength and capacity. To get better with it, we need to make sure we push our body way past our comfort zone each time we do it. Remember, not to rush into strenuous exercise before our body is ready, to avoid injury. Ensure a good warm-up session before starting with it, and end it with stretches.

If you are a novice exerciser, I would say, don’t start with interval training directly. Give your body some time to build the stamina with steady cardio workouts for a few weeks to a month. You can then add interval training to your routine. In fact, you can also add these interval training plans to your gym routine once a week to enhance your speed and cardiovascular endurance.

So what are you waiting for? Jump into your workout shoes and jazz up your workout routine by adding interval training! You can self-observe the changes in your body fat levels. Just pull out a measuring tape, measure your inches before you start with the training and re-measure them after a good gap (say, after a month). You may be surprised with the result. There may be a subtraction in your inches which indicates a drop in fat percentage.

P.s. If you have a chronic health condition (Hypertension or Cardiovascular illness), it’s better to keep away from interval training to avoid any aggravation.

How much cardio should you do?

 

cardio exercise

 

CARDIO- The only form of exercise which has grabbed everybody’s attention and why not, almost all the common activities are a form of cardiovascular exercise.

Whenever I ask someone about what exercise you do throughout the day- their reply is mostly WALKING. Hours of walking sometimes.

So, what does cardio include?

  • Walking (As already mentioned above)
  • Running
  • Swimming
  • Cycling
  • Aqua-aerobics
  • Aerobics
  • Zumba
  • Rowing
  • Boxing

I have seen people concentrating only on cardio exercises for years without any change in their routine. Some people consider themselves to be fit with simply walking.

Fitness is measured by different things and not just your overall structure.

As a part of your fitness routine, these 3 components are very important which is as follows: –

  • Cardiovascular exercises
  • Strength training exercises
  • Flexibility exercises

None of the components can be skipped.

All these 3 components are very important for a proper fitness regime.

The question which I always get is (which also became an idea to write this article) how much cardio should I do?

And my answer is (Always), you should actually ask how much of these 3 components I should do?

Well, I will be covering all these 3 components in 3 separate articles so for now, I will be concentrating on cardio.

So, going back to the question which I always get, I wish I had an answer to that which could be as simple as

Do 60 minutes a day or maybe 150 minutes a week!

But being a healthcare professional, I cannot give a generic answer.

In fact, that question has no specific answer.

The amount of cardio which should be done completely depends upon these 4 factors: – (Ps: – Please read all the factors before you come to a conclusion for yourself)

cardio ex1

(1) It depends on what you are aiming at.

Well, not everybody needs weight loss! Some people might be looking for muscle gain while someone else might need to run a marathon.

So, does that mean all of them will be doing 150 minutes of cardio per week?

Definitely not!

Along with the aim, you also need to know about your metabolism.

Metabolism is the rate at which your body needs calories while resting.

So, for a person who wants to lose weight will probably be needing a lot of cardio but for someone who wants to build muscle- the amount of cardio which you require completely depends on your metabolism. If you have a fast metabolism then you don’t need any cardio but if your metabolism is slow then you need to do some amount of cardio.

Someone who is into different sports like shot put or powerlifting or sprinting might require very little cardio.

Why am I targeting these 2 categories first?

It is because losing weight and gaining muscles are totally different things to talk about. For your body as well, it becomes a very confusing state because the body cannot do 2 things simultaneously. However, with proper training, it does become possible sometimes.

Then, what about fat loss? How much cardio should one do?

If losing weight is your only goal then it is okay to put your focus more on cardio and neglect the muscle gain part.

You just work on not losing muscles while you are losing your fat.

This can be achieved by 2 times a week strength training and adequate proteins in your diet.

What If someone is a marathoner? How much cardio should one do?

It also includes a good amount of cardio and minimum strength training but flexibility here is very important. It can all be divided throughout the week with a focus more on cardio and other endurance sports.

Although I don’t like putting anything in a restricted way I guess I can do with sharing some guidelines about the first factor which I have discussed in brief above so that it becomes easier for everyone to understand.

  • Building muscle + Fast metabolism = No cardio
  • Building muscle + Slow metabolism = 2-4 days per week with about 20-30 minutes every day.
  • Losing fat = 5-6 times per week with about 45-60 minutes every day
  • Marathoner= 4-6 times per week with about 30-60 minutes every day

*This is very generic; the requirement might differ in each person but this can be used as a guideline to work upon.

(2) State of your hormones

Well, the most common problem which most of us are facing is WEIGHT GAIN or UNABLE TO LOSE THE EXISTING WEIGHT which ultimately makes you hit the gym and your trainer will suggest you do cardio. He or she will decide the plan and everyone blindly follows that plan. But, do you think everybody needs exactly the same amount of cardio?

When your weight becomes a problem the hormone which comes into the picture is CORTISOL.

Cortisol is a hormone which is released all the time in the body but most commonly it reaches its peak under extreme stress. When the stress is often short-term like some assignment to complete or some exams to give then the graph of cortisol keeps fluctuating but when the stress becomes long term which goes on for months and years then the gland which produces cortisol is adrenal glands that starts burning out which means there won’t be enough cortisol which is produced. Well, none of this is good. Neither LOW nor HIGH. Everything goes well in balance.

So now that was about the theory, let’s understand how to practically apply it.

Symptoms of cortisol imbalance: –

  • Rapid weight gain
  • Muscle weakness
  • Chronic fatigue
  • Mood swings
  • Anxiety
  • Depression
  • Confusion
  • Insomnia
  • Fluctuating sugar levels

 

How to know about your cortisol imbalance?

  • It is important to do a stress test first and then go for the lab reports and get your 8 am cortisol checked.
  • Visit an endocrinologist with your reports.

 How much cardio should you do if your cortisol levels are not up to the mark?

  • Under 60% of your maximal heart rate.

How to calculate your maximal heart rate?

  • 220 – your age= maximal heart rate

For example: –

Person who is 40 years of age,

220-40= 180 (Maximal heart rate)

60% of 180 = 108 beats per minute.

  • You should not cross 108 beats per minute while doing cardio in any case.
  • You must strictly monitor it and get yourself a personal trainer/coach who can help you understand this.

Why are we discussing cortisol imbalance and what is the reason behind reducing your cardio activities in such cases?

treadmill-2581437_640

  • All the exercise puts the body into some stress. This stress can affect stimulation of different hormones.
  • When you do steady cardio like a treadmill or cycling your body increases cortisol and reduces other hormones like growth hormone.
  • When you do interval training your body increases cortisol and growth hormone
  • When you do strength training with moderate repetition and sets your body increases growth hormone and cortisol by a small margin.
  • When you do strength training with heavy repetition and sets your body increases testosterone (Which is mostly seen in bodybuilders)

I have given you an in-depth reason here so that you can understand that doing cardio under any stress will increase the complication even more and will do no good to your body.

So before getting into intense workouts, check your cortisol levels.

If everything is okay then you can do the cardio as discussed above.

(3) Depends on your intensity

Whenever I try getting the history about exercises, I get to hear this very often: –

” I do cardio for about 1 and half hours in the gym but I am not getting any results “

” I walk for about 2 hours a day, one hour in the morning and one hour in the evening but I don’t think it is helping”

Well, the basic point to this is,

YOUR DURATION DOESN’T MATTER.

WHAT MATTERS IS- YOUR INTENSITY.

You can work out for just like 15 minutes and still get the same effect as you might get it from longer duration.

Since a couple of months, I often see people talking about high-intensity workouts, low-intensity workouts. I was actually very curious to know their definition of these workouts. I was actually very surprised to know that out of 10 people not even 2 of them knew what exactly it is. They were talking about it because they read it on the internet or their trainer told or something else. You don’t need to be a doctor or personal trainer or a certified health expert. You as a common man to have the rights to know, after all, you are the one who is actually, going to follow that advice. Well, writing this article in this depth is just for everyone to understand the basics behind all the theories which are coming up.

So, coming back to the theory behind intensity.

What is a low-intensity workout?

  • Under 60% of your maximal heart rate (How to calculate it is mentioned above) is a low-intensity workout.
  • These intensity workouts will not increase the endurance but do have relaxation benefits.

What is moderate intensity workout?

  • In between 60-85% of your maximal heart rate is moderate intensity workout.
  • This is a basic workout if your goal is to lose fats.
  • Start with 3-4 times per week and for 30-45 minutes
  • This is just about cardio however in this routine strength training is also required which will be covered in the upcoming article.

What is a high-intensity workout?

  • Anything above 85% of your maximal heart rate is high-intensity workout
  • This can be maintained only for about 1-4 minutes before your speed drops and then gradually goes ahead.
  • Start with 2-3 times per week for about 20 minutes.
  • This course will include proper strength training also which will be covered in upcoming article

Note: – High-intensity workout is not suggested for anybody who has not done any cardio exercises for past 4 months, for someone who has serious cardiac issues. Please consult your doctor before getting into these kinds of workout. Inform your coach and coaches too can take this as a basic part of history taking.

(4) Depends upon how well your response to cardio exercises.

  • As I mentioned in the beginning of the article, every individual is different and there is no same answer to HOW MUCH CARDIO YOU SHOULD DO?
  • It all depends on your responses which can vary from person to person
  • I can simply guess that maybe you require this much workout but I am never sure about it unless I check the response for minimum 15 days.

My players always ask me that why do I give the workouts for 15 days and then think so much for the next set of workouts. Sometimes it so happens that I refuse to change the workout and make then repeat it for 15 days. I know it’s annoying, like very annoying but it is better than any serious injury. Unless I am sure about the responses and progress I do not go ahead in case of workouts.

This article only gives you insights about CARDIO but your workout routine is incomplete with strength training and flexibility.
