Eric Holmstrom

Brazilian Jiu-Jitsu Coach

Eric has been training and competing in Brazilian Jiu-Jitsu (BJJ) since 2009. Looking to lose weight and couldn’t keep momentum lifting weights, he walked into a gym near his bus stop.

“I remember rolling with Karen, a blue belt and tiny in size. I learned to tap real quick that day and here I was thinking I would be the one going easy.”

Eric fell in love with the martial art ever since and was awarded his black belt (and all belts) under Fabio Glazer and continues to compete to this day.

Lineage: Mitsuyo Maeda -> Carlos Gracie -> Helio Gracie -> Rickson Gracie -> Jorge Pereira -> Paulo Guimaraes -> Fabio  Galzer

Liam Minett

Strength & Conditioning Coach and Kids Coach.

Liam I lived the corporate life for 20 years and loved it. Travel, clients, deadlines, stress, dinners and booze. It wasn’t until I came out of the other side, that I realised the toll on my physical and emotional wellbeing, and on my relationships.
I’m all about progress, each day better than the previous, each achievement a step up from the last, and I know I’m my best person when I’m strong.

Achievements

Outside of my private practice, I’ve trekked Kilimanjaro 5895M, done a little mountaineering: glacier hiking, day climbing in the alps and summiting Gran Paradiso x2 (Italy) 4061M and Mont Blanc (France) 4808M. Completed an Ultra Trail marathon 100Km in the Blue Mountains and started my Brazilian Jiu Jitsu journey 3 years ago. I also teach a strength and conditioning class weekly.

I’m cert 111/1V qualified in personal training.
