Jasen started practising Calisthenics in 2012 and in 2014, began coaching others when Singapore Calisthenics Academy was founded. The reason he took up Calisthenics was to conduct an experiment of his own. He wanted to see if it was possible for him to develop an aesthetic physique simply by lifting his own bodyweight. As he trained more and more, he began to explore more of what Calisthenics has to offer. What started as just a workout to build more muscle, eventually turned into a training more specific for achieving advanced Calisthenics skills. As his passion for exercising grew, Jasen decided to take a bachelor’s degree in Sports Science at the Nanyang Technological University in order to become more knowledgeable in his fitness venture.

Jasen has also been involved in athletic Calisthenics events. He has competed in the Weighted Calisthenics Category in the Asia Street Workout Championship in 2015 and the BiaAthletics Street Workout Competition in 2019, coming in second and first place respectively. For up to 8 years, Jasen has helped many achieve their goals, from acquiring Calisthenics skills, to building strength, to getting out of pain, and to reshaping their bodies. He strongly believes that Calisthenics is such a versatile form of fitness that everyone should do it. He is always willing to step forward to help those who are ready to commit to becoming a stronger version of themselves.
