Self Defence For Women
Tim’s workshop has provided me a great insight of defending myself in dangerous situations. It was comprehensive and easy to understand. Started with knowing nothing about self defence, I walked away with confidence of protecting myself in just 2 hours.

Self Defence For Women
Tim’s self-defence class gave me the skills to be more confident in being able to protect myself as well as making me more aware of my surroundings and being able to read situations before they got out of hand. Thanks Tim.

Tim, thanks again for your demo yesterday afternoon on using the foam roller. I was always under the impression that as long as you felt OK (i.e. no sore points) then that indicated that the body was basically relaxed. Your simple demo yesterday has blown… read more

Tim helped me turn around my health and fitness completely. After 27 years of inactivity, he showed me the way to a healthier, stronger and rewarding way of life, and all in such a short time. My hat’s off to you my friend.

    Been training in martial arts for 15 years, I appreciate the quality of Sensei Tim's instruction and the depth of his skill. Incredibly honoured to be a part of the academy

    Had no idea what i was getting into upon engaging this class for my daughter, at her own request.. But it's been the best few years worth of memories of our lives. For my little girl and for me as well ! Thank you very much sensei Tim🙏.

    My daughter does kick boxing sessions weekly at personal strength. She enjoys the supportive and safe environment whilst having fun keeping fit. Tim has created a great space for young people to be the best version of themselves.

    UPDATE: it's been almost 5 years since I left this review. We're still going strong! I'm still training with Tim 💪 My now 10-year-old son is still doing Ninjas classes 👍 Great local gym with a very welcoming environment. I've been training with Tim for almost 2 years and I always enjoyed his personalised approach which helped me to achieve my goals. Tim is always very encouraging and makes each training session challenging, but rewarding. Apart from training adults, Tim is excellent working with kids and my 5.5yo son is always looking forward for his next Little Ninjas classes, which he started as a 3-year-old. Kids classes are always fun, with a mix of games and various exercises teaching self-awareness and safety. I would definitely recommend FunFit to everyone.

    Tim always keeps the workouts fresh and interesting and was always committed to safety. Workouts were always challenging but catered to the level you were at. Never a boring session and looked forward to them always. Great community feel and music too! Only reason I'm not going anymore is because I moved to the other side of Sydney.

    Ruth Hawkins
    Both my 4 year old girl and 6 year boy absolutely love the classes. They've done lots of other activities over the years but there's something about being a little ninja that makes them light up and they enjoy every minute of the class.
