Circular, triangle, and square

Instructions for breathing patterns can be delivered concisely and precisely when displayed graphically. It’s common to use basic geometrical shapes to illustrate a breathing cycle. The most commonly used shapes are:

• Triangles: One breath-hold added to a breathing cycle.
• Rectangles: Two breath-holds per breathing cycle.
• Circles: Connected continuous breathing without breath-holds

Geometric shapes illustrating breathing sequences

Pendulum breathing is a variation of circular breathing, where inhaling and exhaling are in equal parts (like a pendulum).
