What's your Gravitype?
Each of us relates to gravity in a unique way. Some people move through life with ease, steady and balanced. Others feel weighed down, dizzy, or anxious under its pull. These differences form your personal profile of gravity resilience, known as your gravitype—the way your body and mind adapt to Earth’s constant force.
Your gravitype is shaped by three dimensions:
- Gravity Fortitude – your physical durability and internal strength.
- Gravity Sensing – how sensitive your nervous system is to gravity’s effects.
- Mental Gravity – your emotional orientation toward life’s ups and downs.
Together, these create eight distinct gravitypes, ranging from the resilient Gravity Master to the Overwhelmed Defender. Knowing your gravitype can help explain why certain activities (like flying, roller coasters, or even standing up quickly) feel easy—or overwhelming—and what you can do to strengthen your resilience.
