Fitness has a different definition for people, while for someone it may mean being an ideal weight, for others it may be gaining muscle. And all of these have different types of exercises, diets and other lifestyle changes which will help them reach their goal in a reasonable amount of time. One thing that everyone must understand is that you cannot rush fitness, but you can maximize your ability to reach your goal quicker. Maximizing means making the most of the opportunity, for example, you have an hour to exercise every day and you wish to lose weight, to maximize your opportunity you must fit in cardio that allows you to burn calories easily like Stairmaster, running on an inclination, as well as weightlifting. And on the other hand, if you wish to gain muscle, you will focus more on weights and lifting the most you can. Muscle gain is said to be a difficult task as you are practically depending on the wear and tear of your muscles to build them bigger.

While there are many ways to gain muscle periodization has shown to have better results in the long run.

What Is Periodization?

Think of periodization as planning your workouts like a coach plans a game. Instead of just showing up and doing the same thing every time, you break your training into different stages, each with a specific goal. It's like building a house, you don't start by putting on the roof! You lay the foundation first. Periodization helps you do the same with your fitness. You might spend some time focusing on building a base level of fitness, then move on to building strength, and then maybe work on power or speed. By changing things up regularly, you keep your body guessing and avoid hitting plateaus. It's all about working smarter, not just harder.

Periodization isn't just some random idea, it's based on how our bodies work. When you exercise, your body experiences stress. It reacts to this stress in a predictable way, going through different stages. Periodization uses this knowledge to its advantage. It pushes your body just enough to make it adapt and get stronger, but not so much that it gets worn out and injured. Think of it in food terms, not too hot, not too cold, but just right. Some of the benefits of periodization include getting stronger or faster, avoiding overtraining which can actually make you weaker! preventing injuries, staying motivated because you have a plan, and seeing consistent progress over time.

Can Periodization Be Used For Other Sports?

Periodization is a discipline that can be applied in many places. Periodization isn't just for bodybuilders or athletes; it can help anyone who exercises.

It can be used for strength training, if your goal is to build muscle, periodization helps you cycle through different phases to maximize growth. It is also useful for people who are into endurance training like runners, swimmers, and cyclists use it to prepare for long events by focusing on different energy systems. For athletes in all sports use periodization to peak at the right time and avoid getting injured during training. Even in bodybuilding, where the focus is on aesthetics, periodization plays a key role in maximizing muscle growth and achieving that competition-ready physique.

Putting periodization into practice takes some planning. First, you need to know your goals. What do you want to achieve? Then, choose a periodization model that fits your goals and how much experience you have. Next, divide your training year into phases, each with a specific purpose. This might be a few weeks or a few months long. Then, adjust your training volume which depends on how much you do, intensity which is how hard you work), and exercises to match each phase.

Most of us know exercise is good for the heart. It makes the muscle stronger and brings the resting heart rate down. But new research from the University of Bristol suggests there is another layer. Regular exercise may also change the nerves that tell the heart how fast to beat.

What The Researchers Did

The heart is partly run by the autonomic nervous system, the body’s autopilot. It handles heartbeat, breathing and digestion without you thinking about it. According to a University of Bristol statement, the team studied rats that did 10 weeks of moderate treadmill running. They then examined the stellate ganglia, two small clusters of nerve cells on either side of the lower neck and upper chest. These clusters send the “go faster” signals to the heart.

The study appeared in the journal Autonomic Neuroscience, with researchers from University College London and two Brazilian universities.

In untrained rats, the left and right clusters looked fairly similar. In trained rats, they did not. Healthline, reporting on the paper, said the right cluster held about four times as many neurons as the left. The nerve cells also changed size in opposite directions. Those on the left grew to nearly twice their size, while those on the right became slightly smaller.

The trained rats also had a lower heart rate, around 280 beats a minute against 314 in untrained rats, while their blood pressure stayed about the same, according to Healthline’s report on the study.

Why It Matters

Doctors already target these nerve clusters in some patients. Nerve blocks and denervation procedures calm them down to treat irregular heartbeats, angina (chest pain from poor blood flow to the heart) and stress-induced “broken-heart” syndrome.

Dr. Augusto Coppi, the study’s lead author, said in the University of Bristol’s statement that the clusters work like the heart’s “dimmer switch.” He said that knowing how they differ on each side could one day help doctors pick the side most likely to benefit.

This was a rat study. Dr. Coppi himself said in the same statement that the findings are early-stage and that clinical studies would need to follow. The team still has to show how these changes affect the way the heart actually works. They plan to test larger animals and eventually people, using noninvasive markers so no surgery is needed.

So this is not a new reason to change anyone’s treatment. It is a clue, not a cure.

The advice itself is old and well proven. The World Health Organization recommends that adults aged 18 to 64 do at least 150 to 300 minutes of moderate aerobic activity a week, or 75 to 150 minutes of vigorous activity. Brisk walking, swimming and cycling all count. WHO data also shows that about a third of adults worldwide still don’t do enough.

If you have a heart condition, get chest pain, or take heart medicines, check with your doctor before starting a new routine. For everyone else, the message is simple. Your heart is not the only thing that changes when you work out. The nerves that control it may change too.

For someone living with obesity today, the treatment conversation has become more complex and, in many ways, far more hopeful. With newer weight-loss pharmacotherapies offering significant results, patients and clinicians now have more options than ever before. The key question is no longer whether medication or surgery is better, but rather which approach or combination of therapies is most appropriate for a particular patient.

Obesity is a chronic, relapsing disease that can affect much more than body weight. It is closely linked to severe metabolic comorbidities, including type 2 diabetes, hypertension, obstructive sleep apnoea, fatty liver disease, joint problems and reduced quality of life. Treatment must therefore focus not merely on short-term weight loss, but on long-term metabolic health and sustained weight maintenance.

How Newer Weight-Loss Medicines Are Changing Treatment

Newer anti-obesity medicines, including GLP-1-based and related therapies, have significantly expanded the options available to patients. They can support meaningful weight loss and improve metabolic health when combined with appropriate nutrition, physical activity and behavioural support. They may be particularly useful for patients who are not ready for surgery, those who need to improve their health before an operation, or those who experience weight recurrence after previous treatment.

However, these medicines do not work in the same way for everyone. Long-term treatment may be required, while side effects, affordability, access and adherence can influence outcomes. Some patients may also regain weight after stopping treatment. In India, the cost and continued access to these therapies are therefore important considerations when planning long-term care.

Why Bariatric Surgery Remains An Important Option

For patients with severe obesity, particularly those with established metabolic complications, metabolic and bariatric surgery remains an important treatment option. Procedures such as sleeve gastrectomy, Roux-en-Y gastric bypass and one-anastomosis gastric bypass can influence appetite, gut hormones and glucose metabolism, in addition to reducing stomach capacity. This can result in substantial weight loss and improvement in conditions such as diabetes and sleep apnoea.

The decision to undergo surgery should be based on factors such as the severity of obesity, associated illnesses, previous treatment attempts and the patient's readiness for an operation and long-term follow-up. Surgery is not an endpoint; nutritional care, lifestyle changes and regular monitoring remain important afterwards.

Combining Medication, Surgery And Lifestyle Changes

Weight regain also needs to be viewed in the context of obesity as a chronic disease. Treatment may need to evolve over time, with medicines, surgery and lifestyle interventions playing different roles at different stages. A patient may use medication before surgery to improve metabolic health, while another may require medication later to manage weight recurrence. This approach allows treatment to adapt to the patient's changing needs rather than treating weight loss as a one-time goal.

Technology is also influencing how bariatric surgery is performed. Technology has fundamentally elevated precision in minimally invasive bariatric procedures. Robotic-assisted surgical systems, such as the da Vinci Surgical System provide three-dimensional visualisation and wristed instruments that flex and rotate with dexterity far exceeding the human hand.

Operating at a dedicated console, the surgeon maintains full control throughout the procedure, as the system translates hand movements in real time with built-in tremor filtration. These capabilities are particularly advantageous during complex reconstructive procedures such as gastric bypass, where precise suturing, micro-dissection, and delicate tissue handling are paramount.

The technology, however, works within a broader surgical ecosystem. Patient selection, surgical expertise, standardised protocols, anaesthesia and postoperative care remain central to achieving good outcomes.

What Real-World Experience With Robotic Bariatric Surgery Shows

Our real-world experience of 545 patients undergoing robotic bariatric surgery with the da Vinci Surgical System showed consistent outcomes across procedures, including in patients with severe obesity. There were no conversions to open or laparoscopic surgery, the 30-day post-discharge complication rate was 2.02%, and no mortality was reported during follow-up.

At one year, mean BMI reduced from 44.55 to 32.68 kg/m², while outcomes in patients with BMI ≥50 kg/m² remained broadly comparable with the overall cohort. For patients, this translates into predictable perioperative outcomes and meaningful weight reduction, while for surgeons, the experience demonstrates how robotic assistance can be integrated into bariatric practice, including the management of technically challenging cases.

The changing obesity landscape ultimately calls for a comprehensive, personalized approach to treatment. Anti-obesity medications have expanded the options available to patients, while metabolic and bariatric surgery remains the cornerstone intervention for those who require substantial, durable weight loss and metabolic improvement. Neither approach should be viewed in isolation from nutrition, physical activity, behavioral health, and long-term follow-up.

High-intensity interval training (HIIT) has gained popularity among those who wish to achieve a good workout in a short amount of time. But for those with high blood pressure, the challenge is an important one: Can they attempt HIIT, or is it too much for the heart?

The answer, in short, lies with the individual. Having high blood pressure does not mean that a person has to avoid vigorous exercise, but the intensity has to be suitable considering the blood-pressure control and cardiovascular risk, fitness levels and other medical issues.

In India, where hypertension has become a growing public health concern, an ICMR-INDIAB study which looked at more than 113,000 people across the country, put the overall prevalence of high BP at 35.5 per cent among adults aged 20 years and above. It was higher among men and the urban population.

Blood-pressure control remains a concern in India as the WHO-India estimates that around 220 million people live with hypertension but only about 12 per cent have their BP under control.

So where does HIIT come in?

HIIT, which involves alternating short periods of high-intensity workout followed by recovery periods, can actually be beneficial. HIIT is not forbidden among those with high blood pressure, but the individual has to take stock of several factors before starting such exercises.

Those who are physically active, have good blood-pressure control, and no other concerns can probably take on HIIT workouts. But those who are sedentary and/or have poor blood-pressure control may have to work their way up. This is an important point to consider as HIIT might offer a good workout, but a hard-hitting workout is not always good for your blood pressure.

Start with assessment, not max intensity

Among those who are new to exercise and have hypertension, jumping into an intense HIIT workout may not be the best move. A doctor would look at blood pressure, age, exercise history, cardiovascular risk and symptoms before advising on the most appropriate way forward.

A sedentary person should start with brisk walking, for example, before working their way up to cycling or jogging, and then adding higher intensity workouts, or interval training. It is about pace and control, and not going all out right at the start. Not only is that risky for those with hypertension, it could also lead to severe injuries.

Pay attention to exercises that help you warm up and cool down, and avoid stopping abruptly immediately after a vigorous round of exercise. While doing strength-based HIIT, people should avoid holding their breath, as this can cause blood pressure to spike. Make sure you train with a qualified trainer who can guide you through your workouts safely, and with the right advice.

What about people with uncontrolled BP?

This is the point where exercising caution is important. People with high blood pressure who have persistently high or poorly controlled readings should not assume that every form of exercise is a good idea for them just because it is termed healthy.

Unexplained chest pain or discomfort, breathlessness or dizziness, fainting or unusual palpitations during exercise are signs that a person should stop their workout and get to a doctor rather than powering through the routine.

Those on antihypertensive medication will also need to take stock of their medication, how their blood pressure is behaving, and how their body is responding before deciding on the best approach to exercise.

The goal is sustainable cardiovascular fitness

For Indians looking to get into intense workouts, HIIT can be a part of a physically active lifestyle, but the aim should be cardiovascular fitness, not necessarily high-intensity workouts. Physical activity continues to be an important pillar in the management of blood pressure, alongside a balanced diet, weight control, adequate sleep, reduced salt intake, medication when needed and regular health check-ups.

So the right question for a person with hypertension is not: ‘Can I push myself as hard as possible’, but ‘What intensity is appropriate for my heart and blood pressure?’
