The Concept
NUMBER 3 was born from the vision of creating a fitness boutique that offers a premium training experience in a comfortable environment that feels like home.
The name – NUMBER 3 – reflects who we are and what we believe in. Our commitment to excellence, built on close relationships with our clients, makes our fitness boutique feel like your very own home gym.
This dream comes to life in the NUMBER 3 space: an exclusive studio designed for personalized training, thoughtfully crafted to offer a welcoming, functional, and technically advanced environment. Every detail—from the layout to the equipment selection—has been carefully considered to ensure a safe, efficient, and truly customized training experience.
At NUMBER 3, we believe that the environment in which you train is just as important as the method itself. That’s why we’ve created a space where body and mind find balance, purpose, and growth.

Our Philosophy
Our training philosophy is based on the integration of knowledge from different fields, namely neuroscience and joint and muscular physiology. At NUMBER 3, we look at the human body always considering the interrelationship between the brain, muscles, and joints. Each of these parts influences the others
As a starting point, we carry out a careful analysis of each client’s physical condition to establish a work plan suited to their abilities and goals.
Our premise is the quality of execution, joint ranges of motion, and the duration of exercises, which must always be appropriate to improve the daily physical condition of our guests, always respecting their comfort and safety.
At NUMBER 3, improved mobility and performance, increased muscle mass, fat loss, and increased strength will be the result of enhancing each individual’s capabilities and the natural consequence of working together with one of our trainers. Training at NUMBER 3 is a tireless pursuit of our students’ improvement.
Our modus operandi includes the fulfillment of three distinct and complementary components:
Physical Assessment
Our guests’ training programs are built according to an assessment process that analyzes a set of variables, namely: medical history, athletic background, body composition, joint mobility (identifying movement dysfunctions), and availability for training.
Training
The individual is at the center of the entire process.
As previously mentioned, our methodology is based on the integration of knowledge from various fields, namely neuroscience, musculoskeletal physiology, biomechanics, and physics.
By combining these multiple disciplines and grounding our approach in the brain-muscle-bone equation, exercises are developed according to each guest’s unique capabilities.
Well-being
Our approach to helping those who seek us combines training, nutrition, and lifestyle, promoting healthy habits and encouraging the adoption of positive behaviors.
We share knowledge that empowers our students to become more autonomous in their daily choices.
The space
The NUMBER 3 facilities are located in a quiet area of the municipality of Oeiras and offer all the conditions necessary to ensure the comfort and privacy we wish to provide.
In addition to the fully equipped training area, the space features a lounge—offering water, coffee, and snacks to our students—and three individual changing rooms with all the necessary amenities.


Adaptive Structure
At NUMBER 3, all sessions are 30, 45, or 60 minutes long and are available every day at a time that suits both our guests and their trainer.
Sessions take place at our facilities, which offer the comfort and carefully selected equipment designed specifically for the execution of the NUMBER 3 methodology
Our guests commit to their trainer on a monthly basis, making their satisfaction and needs the main driver of their connection with NUMBER 3.
