My name is Ekaterina Nenkova and I am a NASM Certified Personal Trainer (National Academy of Sports Medicine), AfN Certified Nutrition Coach, member of CIMSPA and founder of Trainer Premium.
I started my fitness journey 12 years ago as a fitness enthusiast and went through different phases of my self-development, experienced injuries and downfalls, but at the end of the day my dedication and eagerness to learn helped me achieve every single goal I had set for myself.
With the professional qualifications I have I am committed to supporting, developing and enabling people to succeed in their own body transformation journey and inspire them to become more active.
As one of the first qualified NASM personal trainers in Bulgaria I am also registered in CIMSPA (The Chartered Institute for the Management of Sport and Physical Activity) which is an additional proof of the professionalism of the organization. CIMSPA is the professional development body for the UK’s sport and physical activity sector and is in partnership with EREPS (European register of exercise professionals).
Truly Yours
The personalized programs are designed to aid beginner, intermediate and experienced lifters in significantly improving their overall stabilization & endurance, strength, maximum strength and power. This is done by using specific training protocols, exercise guidelines and modifications to acute variables such as sets, reps, and volume.
The NASM’s exclusive OPT model which I am using in order to design the training programs simultaneously improves all physical abilities, such as mobility & flexibility, muscular and aerobic endurance, core stabilization, balance, muscular strength, coordination, and power.

Whether you are going to a gym or have some equipment at home and you are seeking a well-designed gym program to reach your goals, then look no further. My personalized training program, designed with the proven OPT model will challenge you, increase your strength, reduce your body fat, increase lean muscle mass and improve your fitness level and overall health.
I have helped people from diverse population reach their fitness goals- you can be one of them.
Choice & Trust
As a certified nutrition professional from the regulator of nutritionists and nutrition scientists in UK, AFN (Associating for Nutrition), I am developing optimal nutrition plans for regular, vegan, vegetarian and pescatarian diets. I am experienced in creating plans that help you reach your goals- get lean, increase your strength, maintain the results.
Inspiration & Taste
The personalized nutrition plan features breakfast, lunch, dinner and snacks. I’m taking into consideration YOUR preferences and the menu is balanced and delicious (does not consist of oats, chicken breast and cucumber only). My goal with the nutrition plans is to inspire you to make small changes in your daily eating habits that can make a big impact to your health and wellbeing and body image. I know you’re going to love it!

The meal plan is on weekly basis, you have choice of foods for rotation, shopping lists is included as well as delicious recipes so it couldn’t be easier to stay on-track. All the work is done – you simply need to follow the plan and enjoy.
What people say about us

Susan, New mom, UK
Ekaterina is an excellent personal trainer I would recommend to anyone who has been struggling with getting rid of that baby weight. I am simply loving the postpartum results, which I wouldn't have been able to achieve on my own. She also tailored for me an easy to follow meal plan which helped me lose 10 kg in 4 months. Thanks to her constant support I am in a great shape and have the energy to face the challenges of being a new mom.
Mark, Manager, UK
Working home office during the past 12 months had its toll on me both physically and mentally. I started gaining weight, suffered constant back aches and felt demotivated to do any leisure activities. Thanks to Ekaterina’s constant support and motivation during these last months, I can now say I have more lean muscle than pre-pandemic. I've said goodbye to the back aches and as a bonus, my mental health has improved!

Annabelle, Student, UK
Over the past 7 years I have been fighting a losing battle to shed some10-15kg and shape up my body. I have tried countless diets, training programmes and activities in order to achieve my goal but found it difficult to stick to a regime or a programme and lost motivation sooner or later, before I could see any significant results. Although I was reluctant to try yet another training regime, a close friend of mine told me about long Trainer Premium and how happy he was with her tailored solutions and his progress. Kate, thank you for helping me be consistent with a programme for the first time in my life! Your relentless support over the past 6 months is the reason I am in my best shape in the last 5 years
