Christian Ch’ng

Christian began his Martial Arts journey in Karate at the age of 6 training under his Father a Karate Black Belt at his small Dojo.

As a teenager he went on to study Judo and Kung Fu but it wasn’t until leaving school that he realized Martial Arts were the only thing that really kept his interest and decided to pursue his passion with more of a fulltime commitment.

He went on to train in Kickboxing, Muay Thai, Kyokushin Karate, Boxing and BJJ but it was Shidokan ,a style that combines all the training Christian had done in the past which felt the best fit. Shidokan takes the best elements of Karate, Kickboxing and Grappling with the principles of Budo to formulate a well rounded style of Martial Arts.

Christian graded to blackbelt with the legendary Kancho Yoshiji Soeno founder of Shidokan in 1997.

With over 35 years of martial arts experience Christian is still a student aiming to be as well rounded a fighter as possible. He hopes to share the lifestyle and benefits that martial arts has to offer with anyone willing to learn.

Sarah Steinbeck-Phillips

Creative Movement and discipline were instilled early in Sarah by way of Classical Ballet studies from the age of 8. Whilst at Uni her ballet studies continued at the Sydney Dance Company concurrent with studying for her Bachelor of Commerce (Marketing) at the University of Western Sydney. After graduating Uni Sarah was offered work at the prestigious International law firm Minter Ellison Lawyers as National Data Base Manager a position she was in for 5 years.

During Sarah’s time at Minter Ellison Lawyers, Sarah saw that a fast-paced corporate environment must be balanced with a structured exercise regime that challenges you physically so that you can reach peak performance mentally.

With an understanding that Martial Arts offered punching, kicking and somehow something more, Sarah first studied Tae Kwon Do, but it wasn’t until she moved to Singapore and started training in Kickboxing that a real passion developed for the Martial Arts. Upon moving to Switzerland her Kickboxing training intensified and she knew she had found her true path.

In Martial Arts, Sarah discovered that the movement and discipline attained from her Ballet could be transformed into something that still enabled creativity and also had practical life applications physically and mentally. Her Martial Arts journey has since expanded with Shidokan Karate and Brazilian Jiu-jitsu and alongside 8 years of kickboxing experience Sarah is an ISSA qualified Personal Trainer and Certified Power Living Yoga Instructor.

Sarah’s classes are based on Strength, Mobility and Martial Arts and she is keen to share the life balancing way of understanding your own body and mind through movement with clients of all walks of life and fitness levels.
