(parts excerpts taken from http://biagtanmma.com )

Biagtan Martial Arts is a fusion of Muaythai, Cinco teros arnis and Dumog (Filipino wrestling). Maestro Biagtan explained that
in his native dialect “biagtan” means “our life.”
“It’s very appropriate because I am espousing
martial arts as a way of life.”

Maestro Raysaldo also derived his strenght in his belief of Christ. He explained in an interview with FIGHT TIMES ,
“In martial arts we have the so-called inner power and
we must exercise meditation to develop this, and the outside power is
done through physical training. In doing these, you must employ the
dynamic discipline, which is found and flows from your inner self. As an
Evangelical pastor you meditate through the Word of God, open you
heart, let it manifest in you and preach through your action so that you
preach the Word powerfully to the people.

Martial art is for physical-
mind and body, being a pastor is spiritual—heart and soul. Reconciling
these two are simply a way of life, as we live in physical and
spiritual. In Team Biagtan my young trainers and fighters are trained
both being a worshiper of God (spiritual) and servant for people
(spiritual/physical fitness).”
