VAHVA Fitness is a Finnish calisthenics and fitness platform designed and run by Samuli Jyrkinen and Eero Westerberg. VAHVA means “strong” or “able-bodied” in Finnish and uses many aspects of traditional Finnish culture such as Sisu (hardiness, resilience) to instill the proper mindset in its practitioners. Its goal is to overcome mental and physical boundaries in exchange for long term benefits, and to become the very best version of yourself you could be on an evolutionary (genetic) level.
