About Ania

Hi! I'm Ania (or Anna). I discovered bodybuilding while I was in university, and I instantly fell in love! When I started out, I didn't have a trainer, so I ended up with several injuries, and and even a metabolic disorder. After that, I made it my mission to learn from the best (trainers, fitness competitors, and sports medicine and kinesiology professionals), to bounce back stronger and healthier than ever, and help everyone I can to start looking and feeling amazing, while avoiding injury and nutrition mistakes! 

My belief is that there is no "one-size-fits-all" approach to nutrition and fitness, and everyone can fall in love with it, given the right program and right knowledge!

The Plan


Hello friends! I'm Iolanda from Toronto :)  I have been in health and fitness all my life, first as a ballerina, then a ballet teacher, and then discovering the worlds of Barre, Bodybuilding, and Group training. I believe health is all about balance, and fitness is for life, so I prescribe my clients the same as I prescribe for myself: plenty of activities they love, and meal plans they find delicious and easy to stick to.


My background is neuroscience and business. Sports and healthy nutrition is a way of life for me and I am working towards specializing in transformations. I am obsessed with learning new approaches to different theories or goals, be it workout programs, education or ever-changing body goals. I believe that anyone can achieve anything they wish, it's all a matter of finding the right way with smart guidance. To help you succeed, I analyze your goals and current lifestyle from different points, and work on personalized plans and tools

About Alina

Hi there! My name is Alina. I began my own fitness journey when I moved from my beautiful little town in southern Germany to London, England. I remember how lost I felt at the gym, and how difficult it was in the beginning to learn how to eat in a way that would nourish my body and help me perform.

Years later, I am still learning so much, and often it is from clients as I coach them through a new challenge. 

My approach to fitness and nutrition is making it fun and delicious! After all, we want to be fit, healthy and happy for life!
