High Intensity Interval Training and Its Benefits

HIIT and its benefitsYou’ve likely come across the term HIIT in recent years. High-Intensity Interval Training is an exercise routine that many people swear by to get optimal results! While there may be some confusion about what HIIT entails and who should do it, we’re here to clear things up!

What is High Intensity Interval Training?

HIIT, or High-Intensity Interval Training—also known as Sprint Interval Training or High-Intensity Intermittent Exercise—is a workout designed to aid in fat loss and increase stamina.

In this routine, a person performs a burst of high-intensity exercise (like sprinting for 30 seconds) followed by a short burst of active rest (like walking or jogging for 30 seconds) for a total of 4-5 minutes. You then take a minute or two of rest and repeat the same pattern with different exercises.

The main focus of this routine is continuous movement, alternating between high and low-intensity exercises. HIIT is suitable for all ages and can be done 4-5 times a week for best results.

It’s advised to start with a 1:1 ratio of high to low intensity—30 seconds of high intensity followed by 30 seconds of low intensity. As you progress, you can increase this ratio to 2:1.

Benefits of HIIT

  1. Quick Workout For Busy Individuals: HIIT workouts can range from 10 to 45 minutes, combining one or multiple exercises. It’s the perfect workout if you’re short on time but still want effective results. You can burn up to 500 calories in a 40-45 minute session, depending on the exercise and ratio chosen.
  2. Fat Loss: HIIT quickly raises your heart rate to the fat-burning zone and keeps it there, as there’s no rest. This provides excellent fat-loss results in a short period compared to traditional cardio, and the results are noticeable.
  3. Increased Endurance: This routine is highly effective for building stamina, even if you start at lower speeds. Many who practice HIIT have noticed they can run longer and faster after consistently following the routine.
  4. Improved Brain Functioning: Research conducted at various institutes has shown that following a HIIT routine for some time can lead to the following changes that enhance brain functionality:
    • Increases neuron count
    • Improves cognitive function
    • Reduces nerve stiffness and inflammation
    • Promotes new blood vessel development in the brain
  1. Better Physical Performance: Research from the University of British Columbia revealed the following benefits of HIIT compared to traditional, moderate-intensity workouts:
    • Enhanced stamina
    • Greater endurance
    • Boosted metabolism
    • Increased speed and agility
    • Higher peak power

As we can see, HIIT is more than just a popular method for fat loss; it also improves essential aspects of both mental and physical performance. You can add HIIT to your current workout or try it instead of your usual cardio routine for a week.

Here is a Quick HIIT Routine You Can Follow  

  • Jumping Jacks – 1 minute
  • Squats – 1 minute
  • Spot Running – 1 minute
  • Squats – 1 minute
  • Jumping Jacks – 1 minute

Rest for 1-2 minutes, then do 2-4 sets depending on your fitness level.

Effects of Smoking on your Muscles

Quit SmokingIn my fitness carrier so far, I have met many people with all kinds of obsessions. Take my closest friend for example – he’s a fitness and gym enthusiast who wants to develop muscles and also lose fat. However, he had a major misconception: he believed that smoking cigarettes would help him loses fat and that losing fat would automatically lead to muscle gain.

When he approached me to discuss this, I began to wonder—if fat loss were so simple, why would people go through various diets and workouts? Could they simply light a cigarette and shed pounds within weeks? Unfortunately, this is not true.

Some people smoke to appear “cool,” while others believe it will relieve stress and boost happiness. The reality is that none of this happens, and smoking only harms the lungs.

If you’re a smoker, it’s not just your lungs that are at risk; smoking also impacts your strength training. It can make you lethargic. A smoker’s heart beats, on average, 30% faster than that of a non-smoker, which significantly affects exercise outcomes. Since a smoker’s heart works harder to achieve adequate circulation, they expend more energy during workouts.

This increase in heart rate, along with elevated blood pressure, reduces blood flow and hampers the smoker’s performance during the same exercise routine as a non-smoker. If the exercise routine aims at muscle building, a smoker’s reduced performance will yield less muscle compared to a healthy non-smoker.

Testosterone is also vital for muscle building, but smoking may damage the cells within the body that produce testosterone. Low testosterone levels can significantly impact muscle development, endurance, and workout intensity. This may force you to cut down on the workouts needed to make progress in muscle building.

If you’re considering quitting smoking, the health benefits are numerous—from improved muscle development and endurance to better overall fitness. However, if you choose to continue, be aware that the negative effects will likely become apparent sooner rather than later.

Quitting smoking can lead to significant improvements in fitness, endurance, and health. Let us know in the comments if this article helped you!

Do You Really Need Protein Supplements Before and After Your Workout?

protein supplementsAlong with working out and staying active, it is important to take good care of what we eat before and after a workout for energy and tissue repair respectively. Primarily, the go-to in this case is protein but do you get your protein from protein supplements or from natural sources? Which works better? Let’s find out!  

What’s The Difference Between Natural Protein and Protein Supplements? 

You can get energy from natural sources as well as protein supplements. Normally, natural foods like fruits, nuts, eggs, chicken, pulses and cereals contain carbohydrates, proteins and good fats which help us get energy for a workout. They also repair tissues. Supplements on the other hand contain amino acids, B vitamins, caffeine, creatine and artificial sweeteners – quality differs from brand to brand. 

Who Needs Supplements? 

Normally, protein supplements are required for those who perform heavy workouts like athletes, wrestlers and bodybuilders. When the protein requirement is not fulfilled by natural sources, then supplementation is required. Even the amount of protein requirement depends on the person and whether they want to lose or gain weight. 

On the other hand, the amount of protein consumed should also be monitored because if it is not used up during the workout, it gets stored in the body as extra calories as 1g protein contains 4 kcal. The ideal protein consumption should be 1.2 to 1.7g per kilogram of body weight or 0.5 – 0.8g per pound of body weight. 

There are 3 forms of protein: 

  1. Protein Isolates: This consists of only protein (90-95%) and has carbs and fat removed from it through processing. This is mainly made up of whey protein.
  2. Protein Concentrate: is the combination of carbohydrate and fat (20-40%) and protein (20-40%). This is mainly made up of plant sources.
  3. Protein Hydrolysates: This is further processed and breaks the protein into amino acids which makes it more easily absorbed in the body. But it has a big disadvantage – it increases the insulin level of blood mainly which is made from whey protein.

There are many forms of protein supplements available in the market which are derived from various other sources. Comparing the above, try avoiding plant sources as they don’t provide sufficient protein for muscle growth. Whey is easily absorbed and digested whereas casein takes time to get digested but it’s good to consume before sleep as it helps in recovery of muscles and egg protein is another good option as it is easily absorbed by the body. 

Taking all of this into consideration, I would like to say that though it has several benefits, protein supplements also have major demerits such as the caffeine and creatine contents which affects blood pressure, creating cardiac issues by increasing heart rate, causing diarrhoea, a disturbed sleep cycle and gut intolerances, etc. 

Do note that most of these “health drinks” aren’t regulated by the FDA for safety purposes. So, before you pick a protein supplement, read the ingredients on the label and pick one that fits your requirement. Honestly, what I feel is that it is best to fulfil the protein requirement through natural foods! 

We hope this article helps you make a choice! Do let us know your thoughts in the comments below! For more articles on protein, check out Healthy Reads or speak to an expert by subscribing for Personalised Health Coaching here.

Strength Training Benefits For Aging Bodies

strength trainingStrength training is essential for everyone, serving not just to enhance muscle strength but also to bolster overall health regardless of age. Whether you are 25 or 65, incorporating some form of strength training into your daily routine is beneficial, though the specifics of the exercises may vary depending on one’s age group.

In this blog post, I will discuss the changes that begin to occur in our bodies as we enter our thirties and forties—changes that are often less than welcome. More importantly, I’ll explore how strength training plays a crucial role in counteracting these changes and significantly enhancing the quality of our lives.

I have experienced the positive changes, that my body has undergone over the last 4-5 years, just by incorporating a strength training routine in the form of workouts with weights, and using my own body weight, as I do in my yoga practice. One can even use resistance bands, the various gym equipment, or own body weight for resistance, by doing push-ups, pull-ups, crunches, leg squats or push-ups against a wall etc.

What Happens As We Age?

The human body goes through changes as we age, and some of the effects are obvious, as we cross middle age. Even healthy, normal ageing includes:

  • A Slower metabolism
  • Decreased muscle mass and strength
  • Increased body fat
  • Reduced bone density
  • Increased bone porosity
  • Stiff joints
  • Slower reflexes and reaction times
  • Decreased aerobic capacity

These are normal changes that we may experience as we age, though the severity varies from person to person. One of the most important reasons to exercise, and specifically include strength training, is to slow and minimize these changes.  

Benefits of Strength Training

1. Increases Muscle Mass
As you age, muscle mass gradually decreases – a condition known as Sarcopenia. Individuals who are less active can expect to lose between 3% to 5% of their muscle mass each decade after turning 30, with this rate accelerating after age 65. By age of 70, the average adult may have lost up to 25% of their muscle mass primarily due to disuse and inactivity. However, this loss isn’t irreversible. Engaging in any form of exercise can help regain muscle mass and strength, but weight lifting, strength training, and resistance training are particularly effective. Research shows that after just six months of strength training twice a week, the biochemical, physiological, and genetic characteristics of older muscles can be rejuvenated by nearly 15 to 20 years.

2. Improves Bone Health
Bone fractures and breaks are quite prevalent among older adults due to decreased bone density and osteoporosis. While there are various causes of osteoporosis that may require medical intervention, substantial evidence suggests that exercise can significantly enhance bone density. Moreover, osteoporosis can be both prevented and managed through strength training. Just as muscles grow stronger with activity, bones also gain strength when engaged in physical exercise. Weight-bearing exercises, in particular, bolster bone health by stimulating the production of new cells.

3. Improves Functional Ability/Movement
Increasing strength through training is crucial for enhancing everyday functionality. Regular strength training enables older adults to enhance their mobility, walk longer distances, and potentially decrease their reliance on assistive devices such as canes and walkers.

Additionally, building strength supports a variety of functional movements, including walking, sitting down and standing up from chairs or beds, climbing stairs or escalators, and carrying groceries. These improvements in physical capabilities make daily life more manageable and empower individuals to engage in a wider range of activities that they desire to pursue.

4. Increases Metabolism
Strength training is highly effective for enhancing your metabolism, which is the rate at which your body burns calories while at rest. Engaging in strength training causes your body to require more energy based on the intensity of the exercise. This not only leads to calories being burned during the workout but also increases calorie burn after the workout as your body returns to a resting state. Additionally, hormones like Testosterone and DHEA, which are vital for strength and energy, naturally decrease with age. However, regular strength training can significantly boost these hormone levels within 8-12 weeks.

5. Improves Brain Health
Aging can increase the risk of loneliness, social isolation, depression, and other mental health challenges. However, building strength enhances mobility and functionality, which can significantly improve overall health, elevate mood, and enhance the quality of life. Additionally, resistance training has been shown to slow cognitive decline associated with aging. Studies indicate that lifting weights can improve memory, attention span, and conflict resolution skills.

6. Improves Health Conditions
Type 2 Diabetes: Strength training effectively lowers blood sugar levels and enhances insulin sensitivity. This improvement helps facilitate the transport of blood sugar into cells, thereby optimizing how the body utilizes glucose.

Cardiovascular Health: When properly executed, strength training benefits both the muscular and cardiovascular systems. Strengthened muscles reduce the workload on the heart, enabling the lungs to process oxygen more efficiently with less effort. This efficiency leads to the heart pumping more blood with fewer beats, which in turn increases the blood supply to the muscles.

How Often Should You Do It? 

It is recommended to engage in strength training three to five times per week for 20 to 30 minutes at a moderate intensity or two to three times per week for 15 to 20 minutes at a high intensity. However, always consult your doctor before starting any workout regimen, particularly if you have any pre-existing medical conditions, and seek professional guidance to ensure the correct technique. This helps in preventing injuries and maximizing the benefits of your workouts, especially when focusing on larger muscle groups which offer greater returns.

Let’s move beyond using age as an excuse and start prioritizing muscle health to enhance both our physical health and psychological well-being!

We hope this article helps you care for your muscles a little more and helps you improve your physical and psychological well-being as well.
