The A.R.T of the Heart

The A.R.T. of the Heart is a framework that helps you build a steady, responsive nervous system. It teaches you to understand your HRV, meet stress with presence, and return to your natural rhythm of resilience and self-trust.

Awareness

Everything starts with noticing. Awareness means learning to recognize your body is always communicating, and starting to understand its unique language. HRV becomes your greatest ally on this journey.

Regulation

Awareness shows you the pattern. Regulation shifts it. This is where you train to be an emotional athlete and build nervous system resilience, learning to breathe through the trigger, choose your response, and stay sovereign even in the storm. 

Transformation

Transformation happens when awareness and regulation consistently meet. This is where old patterns begin to dissolve. You move from reacting to responding, from surviving to living rooted, steady, and connected to yourself.

Truly a life-changing experience, on a level I've never accessed before. I've been fortunate to work with many incredible mentors and teachers over the years, across a wide range of disciplines. But working with Salim took me to a depth of consciousness and self awareness that I've never experienced, a journey that has profoundly transformed my life.

Truly a life-changing experience, on a level I've never accessed before. I've been fortunate to work with many incredible mentors and teachers over the years, across a wide range of disciplines. But working with Salim took me to a depth of consciousness and self awareness that I've never experienced, a journey that has profoundly transformed my life.

What began as a seemingly simple mission to elevate my HRV evolved into a complete life shift — impacting not just me, but my wife, my children, my business, and everyone I care about. Salim's true gift is the energy, love, and deep presence he brings. He has an extraordinary ability to break through ego and emotional barriers, opening the heart to new levels of possibility and understanding. He challenges you, supports you, and expands your view of what's truly possible - not just in performance, but in life itself. My time with Salim has sparked a powerful awakening in me. I am forever grateful for the clarity, healing, and transformation that emerged through this work — and for the new path I now walk with purpose, strength, and openness. I could not more strongly recommend this incredible human to anyone seeking self-mastery, deeper consciousness, and next-level performance in life.

Salim is a true master of HRV, but more than that, he's one of the kindest, most genuine, and thoughtful people I've ever worked with. Through his guidance, I improved my HRV by over 50%.

As the founder and CEO of Orgain and founder of Humble Growth, my life is a nonstop whirlwind of travel, meetings, and high-pressure decision-making. Amid the chaos, working with Salim Najjar has been one of the most grounding and impactful decisions I've made for my health and performance.

Through his guidance, I improved my HRV by over 50%, which is incredible on its own. But what mattered even more were the tools and techniques he taught me—practical approaches that I now use every day to better manage stress, improve recovery, and show up as my best self.

His coaching style is a rare blend of deep expertise and deep empathy. Salim didn't just help me hit a number—he helped me feel better, think clearer, and live more intentionally. I can't recommend him highly enough.

Incorporating Salim's teachings into my daily life has elevated my energy levels, joy, and optimism, allowing me to thrive amidst the chaos of running multiple businesses and 90 flights a year. His expertise, drawn from personal experience, sets him apart as a world-class healer.

Salim has been my close friend and coach for three years, guiding me toward a profound understanding of health and nervous system balance. His teachings seamlessly blend ancient wisdom with modern biohacking techniques. Before working with Salim, I pursued health and happiness without understanding the significance of HRV. As a busy startup founder constantly on the move, my HRV averaged in the 40s, but through Salim's guidance, it now consistently reaches the 70s and 80s, peaking at 122.

His practices have revolutionized how I manage stress, navigate challenges with grace, and regulate my emotions and nervous system. Salim's approach encompasses technology, nutrition, mindfulness, and sympathetic/parasympathetic regulation. His ability to simplify complex concepts in the biohacking world and provide practical solutions rooted in both science and spirituality is unparalleled. He quickly identifies core issues and offers effective solutions, earning him the distinction of being "Salim-approved," a gold standard among our community and even sought after by leading voices in wellness. Incorporating Salim's teachings into my daily life has elevated my energy levels, joy, and optimism, allowing me to thrive amidst the chaos of running multiple businesses and 90 flights a year.

As we progressed beyond the fundamentals of HRV and explored the intricate layers of my interpersonal challenges, profound revelations ensued. Through this transformative journey, every facet of my life has aligned with my guiding North Star.

Salim provided me with real, customized, practical tools and small changes that have had an exponentially large impact. Through working with Salim, I face high pressure situations with beauty and appreciation, a crystal clear mind and calm nervous system. I now intrinsically understand and listen to what my mind and body need and am far more in tune with honoring those needs.

Salim has changed my life. I originally started working with Salim hyper focused on performance optimization and biohacking coaching, my objective was to get a greater understanding of what changes I could make physiologically to professionally perform harder, faster, smarter. From the first session, I very quickly realized that Salim's coaching isn't just performance optimization, but far more than that - Salim teaches life optimization. Salim provided me with real, customized, practical tools and small changes that have had an exponentially large impact. Through working with Salim, I face high pressure situations with beauty and appreciation, a crystal clear mind and calm nervous system.

Salim's wisdom and world class understanding of the interaction between mind, body, soul, is second to none and a single source of truth. Salim intuitively challenges your status quo, whilst simultaneously holding space. I started with Salim hoping for one thing, and came out of his coaching with so much more. Salim is a guide and a light in this world. He has had one of the most profound impacts on my life. When I count my blessings, I count working with Salim twice.

Salim has helped me tap into obstacles and alchemize them into opportunities. There is accountability, caring and wisdom in this container and it's potent. If anyone is looking for the next level of personal and/or professional success and is reading this review…..then this may be an invitation. One of the best investments I have made in myself.

Working with Salim has been a game changer. A healthy nervous system is the gateway to true self actualization. The nervous system is the bridge to an optimal relationship to your environment and self. We can get so clouded with programs of fear and scarcity that we keep unwittingly losing opportunities of expansion during trying times.

While I initially sought out Salim to improve my physical health, what I got was so much more. I'm calmer, kinder, and more present in every aspect of my life, and the ripple effects are undeniable. My employees are happier, my relationships are stronger, and most importantly, I'm kinder to myself.

When people ask what is the one thing I've done that has made the biggest improvement to my health, I say "Salim Najjar". Working with Salim has been nothing short of transformative, and I don't throw that word around lightly. Let me paint you a picture: I'm juggling multiple businesses, keeping up with my rigorous training schedule, and trying to maintain some semblance of a personal life. Stress was overtaking me, and burnout felt like the inevitable destination. Enter Salim. Now, I've worked with my fair share of coaches but Salim is in a league of his own. He's like a walking encyclopedia of modern biohacking techniques and ancient wisdom, all seamlessly integrated into a personalized roadmap for optimizing my brain, body, and soul.

What sets Salim apart is his relentless pursuit of knowledge and his unwavering commitment to uncovering what ACTUALLY makes a measurable difference. Every recommendation is backed by rigorous testing, always on himself first. The result? Disciplines and rituals that I've struggled to implement for years suddenly feel like second nature, effortlessly weaving into my daily routine.

He has gone around the world and immersed himself in techniques from different cultures and was able to transport the relevant teachings to me. I would say single-handed this is the most important mentorship and education I've ever had.

I was lucky to be introduced to Salim through a friend who is one of Australia's leading entrepreneurs. Salim has given me the tools and the education at a masters level tertiary education. This has enabled me to be able to bring out the best in me as a human. He equipped me with tools to enhance my HRV which directly translated to human performance. I became a better husband, friend, son, doctor and human being. He helped me understand the science of the autonomic nervous system and how to regulate this using daily practices. As a doctor I was sceptical at the beginning, but not only did my HRV increase dramatically but I also ceased some of my own medication for chronic Inflammatory conditions.

He has gone around the world and immersed himself in techniques from different cultures and was able to transport the relevant teachings to me. I would say single-handed this is the most important mentorship and education I've ever had.

The value and return on investment is immeasurable. My wife and children have all commented on how present I've become and most importantly how I have embodied calmness and and love. Thank you my brother Salim, I will forever be grateful.

Got Questions?

What is HRV and why is it so important?

Heart Rate Variability (HRV) shows how your body adapts to stress in real time. It’s a direct reflection of the health of your nervous system, how well you recover, focus, and respond with presence instead of reactivity.

When HRV improves, so does your resilience, sustainable energy, and emotional steadiness.

How long does the HRV Fundamentals Course take to complete?

The HRV Fundamentals course is about two hours of content. It consists of 5 Modules that can be watched at your own pace. Each Module is released every 4 days to ensure proper integration of the material. It gives you practical, science-backed tools you can apply immediately to start improving your HRV and build nervous system sovereignty.

What’s included in each offering?

Foundations (Core): A self-paced introduction to HRV, complete with The HRV Fundamentals course, guided practices and protocols from Salim’s favorite partners.

Who is this not for?

This isn’t for anyone looking for a shortcut or a quick hack.


The A.R.T. of the Heart is a framework for real integration, it takes presence, patience, and consistency.

Do I need special equipment?

No. You can begin without a device that tracks HRV.

What makes The A.R.T. of the Heart different?

Most wellness approaches focus on the data and protocols based on other instructors' experiences. This offering and course guide you to understand and listen to what resonates with your body. Salim blends HRV science, psychology, and embodiment, showing you how to translate numbers into awareness, regulation, and transformation.

What if I don’t resonate with the course and material?

We totally understand that this framework isn’t for everyone and offer a 14-day money back guarantee.
