I started with Marcela in 2018 and my results improved very quickly. With follow-up, we noticed the gains with each session. She always adapts the diet according to my training phases, ensuring that I have what I need in each training phase.

I have been with Marcela since 2011. She has always helped me with my supplements and diet. Mainly in terms of recovery during the season.
