The heart is your window to emotional control

We all have the power to control how our hearts respond to stress and the ways in which we connect, compete, and lead during challenging times as well as in everyday life.”

Heart Breath Mind:
Train Your Heart to Conquer
Stress and Achieve Success
by Dr. Leah Lagos, Psy.D.

Stress is not in your head, it’s in your body—
this is the key to peak performance

  • Do you ever wonder how to let go of your fears and achieve your life’s goals?
  • Do you aspire to lead with courage, make better decisions, turn off your busy brain and perform optimally under pressure?
  • Can you imagine what you would accomplish if you had increased focus, improved mood, better sleep, enhanced stamina and greater mental endurance?

In her book, Heart Breath Mind: Train Your Heart to Conquer Stress and Achieve Success, top performance psychologist Dr. Leah Lagos shares her groundbreaking program which has transformed people’s lives in the U.S. and around the world.


The average person takes about 20,000 breaths a day. You would think we would be pros at it by now. We’re not.

The scientifically proven 10-week Heart Breath Mind protocol includes clinically tested exercises that allow you to control your body’s physical response to stress.

This training, paired with easy-to-master cognitive-behavioral exercises, offers a safe and natural process for strengthening health and performance, enabling readers to respond more flexibly to stressful situations, let go of negative thoughts and emotions, and ultimately be more focused and confident under pressure.


Dr Leah Lagos is an extraordinary being. I’ve never known a greater empath. She feels the ripples of the human psyche with a subtlety and sensitivity that is unique in my world experience. I’ve also had the good fortune of observing up close her HRV Biofeedback training with elite mental performers. The vast majority have described the experience as some version of life changing, and I’ve been blown away by the immense performance benefits.”

Whether you’re a martial artist, a CEO, or a student taking a test, being able to tap into instant calm-on-demand is one of the most important life skills. If you can control your emotions and attention, you can navigate whatever happens in life with your full range of abilities. It doesn’t take years of yoga and meditation. Dr. Lagos teaches you how to tap a powerful tool anyone can use in daily life. Her techniques should be taught to every child. It’s not too late, whatever your age, to learn them now.
