Calm on command

Losing control is our deepest fear. As tension builds, stress can catch us off guard — and our performance and wellbeing take the hit. When that ‘always-on’ feeling becomes your baseline, anxiety and burnout follow close behind. You’ll learn how to retrain your body to switch off stress when it’s no longer needed — and stay calm on command.

The best technology for the job

Most wearables track your stress. We teach you to change it. Proprietary technology meets real-world physiology training — translating your body’s signals into insights you can actually use. Simple. Actionable. Science-backed.

And adapt to your needs

Every team has its own pressures. Every individual, their own triggers. That’s why our training is built around you — your goals, your environment, your stress profile.
From performance anxiety to chronic tension, we help you meet pressure with clarity and control.

Soundbites

We work with diverse leaders & leaders in the making from all walks of life

Smiling man with short dark hair wearing a white shirt against a clear sky background.

AJ - Special Operator: “I learnt that I had poor breathing habits, developed over time; skip breathing, chest(costal) breathing to name a few. Aware of these deficiencies I consciously
correct posture, at rest, and maintain a consistent breathing rhythm. I have also adopted nasal diaphragmatic breathing as the primary means of respiration for life. Over time these small changes and inclusions have made a significant improvement to my physical & mental performance and general well-being.”

Tim Paulson, pro athlete CrossFit: it feels like I’ve unlocked a superpower I knew was always there but just out of reach. I’ve gained immense knowledge to better understand my body’s chemical and psychological reactions to stressors, and learned data backed interventions I can use to feel and perform my best.”

Kate, agency director: “I have experienced anxiety and panic in situations when I’m outside of my comfort zone, such as important work presentations. My heart can race accompanied by a feeling of losing control. This has impacted my self-esteem. Stark NKD helped me understand what overbreathing is and my breathing habits causing it, which are depriving my brain of oxygen. Until then, I thought it was my heart! Thanks to this programme I now know what to do when I’m out of my comfort zone to quieten my body and mind by the way I breathe! This knowledge and tools has helped me so much. It will take me time and practice to develop new habits, but I feel so much more empowered. Once you understand what is happening on the inside there is less to feel afraid of. Highly recommend. “

Bridget, financial analyst: “I always thought deep breathing was the right thing to do when I felt stressed. Training with Stark NKD taught me that breathing is not a one size fits all. It turns out that for some people like me deep breathing makes me over breathe. Now I know why I was getting so tired and brain foggy when I did it! Especially after a stressful day at work. Thank you so much for explaining to me simply what over breathing is, and for also giving me the tools to pull myself out of it. How is it that we are only learning about this now?!”

Smiling woman with long straight hair in a circular frame against a plain background.

Kate, head of procurement: “The breathing skills I developed through this programme proved to be invaluable to me in so many facets of life. To name just a few, I had a greater ability to focus which drove efficiencies in the workplace, and a new ability to unlock inner calm which reduced my anxiety. “

Smiling woman with dark hair pulled back, wearing a patterned blouse with abstract shapes in pink, black, and yellow.

“I’d never really thought too much about my breathing. But I was recently diagnosed with an inflammatory auto-immune condition and have started paying more attention to my general health and wellbeing. Thanks to the NKD Breathing System, I now have a much better understanding of breathing and what to look out for. Just like nutrition and everything else, one size fits all approaches don’t work for many people. I love that Anna recognises how individual we each are. It turned out that I’m often a chest breather. By checking in with my breathing more often, I’ve started to reconnect with my diaphragm. I feel calmer and more relaxed as a result. I wish I’d known all of this earlier. Thank you!”

How it Works

Why settle for one-size-fits-all solutions when your physiology is as individual as your fingerprint? Your breath isn’t just mechanical — it’s behavioural and biochemical. It shapes how you think, feel, and perform. At Stark NKD, we combine breathing behaviour analysis with cutting-edge tech to give you real-time insight into what drives — and derails — your state. Together, we retrain your system for balance, control, and lasting performance.
