About Me

Hi, I'm Rai.
The person behind Treethenics.

Calisthenics gave me a reason to keep learning, improving and challenging myself.

As I explored new movements, I became interested in how they fit together: which exercises matched my level, what came before a harder skill, and what I could work towards next.

Organizing those exercises helped me make sense of my own training. Treethenics grew from that idea — a place to explore movements and see the connections between them.
