Stephan Braveboy

Personal Trainer

How can I help you improve your health?

I believe that health should be looked at in a holistic manner, “a complete state of social, physical and mental wellbeing”. I continue to train Capoeira, which has developed my practical understanding of what ‘Healthy’ is and has developed my coaching skills to teach very complex movements, well! Along with that practical experience I have also completed Post graduate studies in Applying exercise for health from St Georges University Hospital. This qualifies me to work with people who may require safe guarding and rehabilitating. I specialise in movement training, rehabilitation and injury prevention designed to get you strong, agile, balanced, flexible and powerful. I design sessions with a mix of client wants along with their needs and ensure that all sessions are challenging and effective! My coaching will not only get you fit and healthy, it will also increase your understanding of how YOUR body works. I aim and succeed in ensuring my clients are well equipped to undertake any physical activity with confidence.

Bettina Keki

Wellbeing Personal Trainer

How can I help you improve your health?

I have been a personal trainer since 2015 and am dedicated to understanding the most effective and efficient way to increase stamina, and wellbeing through training and nutrition.

Being a CrossFit athlete, I've gained experience in functional training, strength and conditioning. I believe functional training can be used to accomplish any goal, from improved health to weight loss to better performance. The program works for everyone, people who are just starting out and people who have trained for years. Functional training is different every day and can be modified to help everyone achieve their goal. The workout program can be adapted for people at any age and level of fitness. I am keen on building a close relationship with my clients and supporting them along their fitness journey.

"Lefteris seems to address the whole person in his work, from the body, to the mind, and can perceive (even over a video call) the slightest indication of pain or injury, and adjusts immediately to deal with it. His charm and humour are as palpable as his skill in seeing the workings of the person in front of him."
