Roman Chair Spine Snake

Think about How YOU want to age.

LIFE requires we bathe and shower, use the toilet, dress, and groom ourselves - a lot - over the course of a lifetime.

The most basic activities of daily living are practically impossible without a healthy spine able to Flex, Twist & Bend at will.

Purchasing a Roman Chair

1. Pelvic Pad Alignment: 45 Degree-Angle vs Horizontal

-45 degree-angled pads naturally reduce the risk of hyperextension (too much backward bending) compared to the horizontal pad alignment.

-Horizontal pads increase the risk of hyperextension, but also place less resting stress on the hamstrings and gluteals.

2. Adjustable Pelvic Pad: Adjustable up & down.

-The top of this pad must rest comfortably where your pelvic bones and belly meet at the crease.

-Smaller individuals may struggle to adjust this pad low enough for a safe practice.

-This pad should NEVER rest in the belly or lower ribs!

3. Leg Support

-Adjust for comfort and support when applicable.

-Designed to prevent the upper body from falling forward during practice.

4. Stability

-For safety, must not break or move during practice.


Message from Roman Chair Spine Snake Founder

Physical aging can be graceful when consistent action is taken to provoke our miraculous inborn potential.

Your body contains that same inborn potential as mine - an incredible potential for healing & performance.

My Roman Chair Spine Snake practice grew from the same place yours will… the beginning & that is where I recommend you start.

Whether it’s an improvement in range of motion or an ability to practice longer each session, continue to challenge yourself.

Keep practicing & age is suddenly nothing but a number.
