In the page's words:

JOMO Studio is an extraordinary yoga studio in the heart of the Belgian Quarter in Cologne - a place dedicated to sound, yoga and movement. We are all about authentic experiences that take you into the depths of your being.

JOMO stands for "Joy of Missing Out" and refers to the feeling of satisfaction and relief you experience when you decide to "miss out" on things and instead spend time alone or doing things that are really good for you.
