Teri took time to understand my needs and goals, resulting in very focussed, well thought out sessions. He's analytical, sensitive and creative, all excellent attributes for a Personal Trainer. Highly recommend - unequivocally.
Lefteris is a friendly, fun and inspiring trainer. He trained myself and my boyfriend together over a few months and showed us a great range of excercises. He was great at correcting form to avoid injury and made helpful and encouraging recommendations throughout the sessions. We worked with him both in the gym and outdoors with no equipment. He kept things fun and exciting in both settings. I highly recommend Lefteris as a trainer.
I decided to start my gym sessions back in May as a part of my weight-loss journey and thought that a good personal trainer could add extra value. I was lucky as Lefteris had availability to support me. He impressed me from day 1 as my first warm up was blended with an interesting discussion about by goal and ways to achieve it. I found him very focussed on my overall needs and changing abilities as sessions were continuously adjusted meeting my progress. Lefteris’s creativity and sense of humour attracted me to have next gym even if I was in a bad mood. As a result, I’ve managed to lose more than 10 kilos and reach my targeted weight with the incredible support provided by Lefteris. Strongly recommend! P.S. He was so good that I asked him to help me with my next goal – mussel growth for attractive body shape. New sessions just began.
Lefteris is an excellent trainer . He assesses my condition thoughtfully and adapts our time together appropriately but with consistent themes . We are now 3 months together and everything works well
Had a great few sessions with Lefteris - I was nursing a few injuries and he was very skilful at navigating around them! Highly recommended.
After an accurate assessment, Lefteris tailored the training sessions to my specific needs. In only a short period of time he has helped me improve my strength and fitness. He has a great personality suited to this role. I highly value his skills and hard work. His experience in rehabilitation is evident. His ability to adapt the sessions to my needs is highly admirable.

Lefteris is a conscientious trainer . He spends the time to understand what your preferences and adjusts workouts based on feedback.

Lefteris is truly one of a kind. The kind of trainer who pushes you exactly when you need to be pushed, but also a trainer who understands anatomy and how the the exercises strength, stretch or repair the body. I always left our sessions feeling that I had improved and that I had challenged myself, by doing exercises that I wouldn't normally do by myself. I'm an avid rower and runner, and have had the pleasure of working with some amazing coaches. Lefteris is definitely one of them.
I’ve had a troublesome lower back for a couple of years. Having tried various therapies from sports massage to chiropractic therapies, I was at my wits end. I began training sessions with Lefteris six months ago and he’s achieved the impossible. My lower back pain, which at times was debilitating, has all but disappeared. Lefteris has a very intuitive and informed approach - I have signed my 81-year old father who suffers from sciatica up for sessions, proof of my trust in his abilities.

Ι worked with Lefteris for quite some time. My involvement is sports left me with a bad case of shoulder ache, not able to lift any weights or perform circular movements. Lefteris was able to help me recuperate from my tendonitis and thanks to him I am able to exercise again without a problem.  He is a great caring person to work with, conveying tons of good vibes! Highly recommended!
