EXCELLENT Based on 41 reviews Megan Simmons2023-10-26Trustindex verifies that the original source of the review is Google. I cannot begin to express how grateful I am for the expertise and guidance provided by Petroula Matthaiaki from Eat Lift Be Happy. With her invaluable support, I was able to break through a plateau and achieve new heights in my weightlifting journey, all while significantly improving my form. I had first observed Petroula training her clients in the gym and I could sense Petroula's genuine passion for helping people reach their fitness goals. Her deep knowledge and understanding of weightlifting techniques, combined with her incredible ability to connect with her clients, sets her apart as a true professional in this field. From the first training session i had with Petroula the most remarkable aspects of working with her is her ability to identify and address mental barriers, knowing i could do more weight. She listened attentively to my concerns and fears, empathizing with my struggles and offering constructive solutions tailored to my specific goals. Under her guidance, I gradually learned to overcome my mental blocks, pushing forward and surpassing previous limitations. Petroula's attention to detail is second to none. She meticulously analyzed my form, providing me with personalised feedback that was both insightful and transformative. With her incredibly keen eye, she spotted even the slightest misalignments or posture issues, helping me optimise my movements for maximum efficiency and safety. Her guidance has not only improved my lifting technique but has also prevented potential injuries. Moreover, Petroula's teaching style is both encouraging and empowering. She creates a supportive and motivating environment through her genuine belief in her clients' abilities. Her positive attitude fueled my enthusiasm, always left me feeling motivated to put in the extra effort required to reach my goals. I am truly thrilled with my progress, thanks to Petroula's coaching. Without a doubt, her passion, expertise, and unwavering support have been instrumental in my weightlifting journey. If you're looking for a coach to help you overcome mental obstacles, perfect your form, help with nutrition advice and take your fitness goals to the next level, I wholeheartedly recommend Petroula Matthaiaki from Eat Lift Be Happy! Ems Loo2023-10-07Trustindex verifies that the original source of the review is Google. Petroula is a fantastic PT! She listens to what you want and tries to accommodate you in the best possible way. From someone who hardly knew about weight training, I feel more confident with the tools and techniques she has shown me throughout our 6 months working together. I chose to do my sessions from home but that didn't stop the continued support and guidance from this strong, happy, motivating woman 🥰 Thank you for everything Petroula, it has been a pleasure 🏋♀️💗 Sarah-Jayne Lovering2023-08-30Trustindex verifies that the original source of the review is Google. Petroula was amazing to work with. She constantly inspired and motivated me to improve and work on myself. Our sessions were fun, and I always looked forward to each and every one! She got me enjoying exercising again, and always gave me inspiration for healthy meals and what I could do to help achieve weight loss outside of the gym. She is missed a lot in Cornwall 😊💪🏻 Thirlwell 102023-07-09Trustindex verifies that the original source of the review is Google. After moving home I joined the gym with the aim of getting my fitness levels back to where I wanted them; I was fortunate to be in some group classes that Petroula was running and made the decision to book some PT sessions with her. The BEST decision I made. Her passion and determination to help you reach your goals is second to none. Her knowledge is incredible and she helps you understand the benefits of eating certain foods; exercising muscle groups together and overall builds your confidence and makes you believe and realise you can do so much more than you thought you could. I want to say a massive thank you to Petroula for giving me that confidence and helping me enjoy my sessions and have a healthier relationship with food. If you’re thinking of taking the next step on your journey and are thinking about some PT sessions you won’t find a better trainer than Petroula. Don’t let age or your fitness level stop you, it’ll be the best decision you make. Rena Komboraki2023-07-06Trustindex verifies that the original source of the review is Google. Too bored to work out. But since I started weightlifting with Petroula both my body and mood changed. I am strong (something I didn’t know about), I feel more confident to go to the gym on my own and I have more knowledge about nutrition. I really appreciate Petroula’s help and professionalism. Not enough words to say thank you!! Ολγα Χρηστοφορακη2023-07-06Trustindex verifies that the original source of the review is Google. Petroula has helped me a lot to change my relationship with food and exercise. Before I started working with Petroula, I used to believe that I have to eat too little calories to see results but that is absolutely wrong. I am so happy that I can enjoy my life while seeing results with my weight loss journey. I cannot recommend Petroula enough. She is so kind and empathetic. Thank you for changing my mindset 😍💪 Felicity2023-07-06Trustindex verifies that the original source of the review is Google. My time with Petroula as my PT was great! Very supportive, understanding and created enjoyable workouts that kept me motivated. Would definitely recommend! Mariya Dimitrova2023-06-23Trustindex verifies that the original source of the review is Google. Working with Petroula has been a pleasure and the best thing I’ve done for my health and fitness. She is very kind, professional and caring. Her knowledge of biology, physiology and fitness is excellent! She has helped me learn how to do exercises safely, focus on my form and how to build and maintain muscle. My relationship with food, exercise and my body have completely changed, I feel like a totally different person. I would recommend Petroula 100% without a doubt. Thank you for everything. 💪🏻❤️ Ειρήνη Χαλκίδου2023-06-22Trustindex verifies that the original source of the review is Google.
