"Working with Fabian is great! He is more than a personal trainer, he provides you with support and guidelines on how to exercise, eat accordingly, change your habits to reach your goal, while being a great motivator. He is eager to see how your body and mind react to the transformation and always explain you in details the reasons behind all steps you take together. Fabian is also very attentive to your emotional balance and suggests relaxing exercises and techniques. All clients are different and Fabian come up with a tailored plan for anyone."
"I’ve been training with One from the beginning and it has been nothing less than a positive transformative experience. Their secret sauce? Not focus on the physics aspects of the individual but a holistic approach that includes everything that affects one’s life: work, sleep, stress etc. The result: a deeper more meaningful relationship that transcends the traditional 2-3 hour relationship you might have with your PT."
"I have a new relationship with my body’s since joining ONE. I learnt how to make better choices eating, drinking and what impact those choices have on my physical and mental well-being. The training plan is tailored to me. Every move makes max effect on my body. I see the difference every day as I look in the mirror. More toned, stronger, 8kg less body weight, more muscle, less fat."
"Glenn is a very dedicated personal trainers who want the best for their clients and always look at you and your situation in a holistic way. I train with Glenn since 3 years through different life stages and no matter where I am at Glenn always tries to find the best solution for training, nutrition and mindset. I can highly recommend ONE and I'm proud to be part of the community."
"I highly recommend Glenn at ONE for his full programme transformations. I've never done weight training before, I exercise a lot, however Glenn has really shown me how this type of exercise is so beneficial for your body shape. Alongside the nutrition advise and coaching I've now finally lost most of the weight gained during pregnancy. Highly highly recommended."
"If you want a gym that will motivate you and help you get to your goals, go to One Institute . 3 months into the program, my transformation is real and i am in the best shape of my life... Yes you do need to put the work in, but the guidance, tools and vision you receive from One will help you get there."
