A trusted private studio for training, recovery and wellbeing in Zurich.
Structured coaching to improve strength, body composition and performance.
SYNERYS was founded by Yuliya Stecher, whose approach to training grew from years of experience in performance sport, coaching and nutrition.
What began as a personal philosophy of intelligent, structured training has evolved into a private studio supported by a carefully selected team of coaches, yoga teachers and wellness specialists.
Together, they guide clients through personalised programs designed to strengthen the body, restore balance and support long-term wellbeing.
One philosophy. One standard of care. One personalised journey for every client.
Julia and I have been training for the last 5 years. We have gone through think and thin literally. I have gained 30Kilos during my pregnancy. Julia has trained me highest level of expertice before, during and after pregnancy.
With her help and a personalized nutrition plan I have lost all the excessiv weight within 4 months. Shes not only me favorite trainer shes also a person i find trust and comfort in.
She is always in a good mood, always has a smile on her face and looks like a goddess.
Working with Julia is amazing. She is full of warmth, understanding, sincerely interested in her clients, personable, professional and extremely knowledgeable.
I love that the Training is 1x1 in a private environment. I have already learned so much about my body and have completed workouts I never thought I could do before.
Julia challenges you but makes it fun and switches it up every session. I love the fact that she is constantly adding new and interesting activities to my workout sessions so I am never bored.
I have never had a workout go by so fast! I cannot recommend Julia’s Personal Training enough.
I have been training with Julia since 2018 and love the great variety of our workouts and stretching. She focuses on my individual goals and needs, and we train in a wonderful atmosphere right by the shores of Lake Zurich. Julia is always in an upbeat mood and challenges you to become the best version of yourself.
