Results through knowledge and dedication

Exercise is my passion, and as a personal trainer I believe that knowing and understanding what we want to deal with is imperative to facing it. That's why since I was 16 years old I began preparing specifically as a resistance training instructor.

I give my maximum effort to achieve what I'm looking for, whether I'm training, studying, or working—I always give my best.

My work excites me, I'm passionate about it, and I seek to help all people who are willing to help themselves. The happiness and satisfaction a client feels when reaching their goals fills me with pride and drives me to give them my best.

I love what I do, and my work has allowed me to train some of the most disciplined and enthusiastic people I know, while in other cases it has allowed me to reveal these qualities in people who hadn't yet discovered them in themselves.

I have over 20 years of experience as a trainer. During this time I have served more than 5,000 people from at least 15 different nationalities, of which more than 240 have become my personal clients.

Since I was 12 years old I have exercised every week almost uninterruptedly until today. At 16 I entered a gym for the first time, at 22 I graduated as a Physical Educator and obtained the most important certification for personal trainers worldwide.

I train people of all ages, from pre-teens to older adults. I have had the experience and joy of working with some of the best professionals in the country in their fields, as well as learning directly from the best in the world.

I have trained clients of all fitness levels, from people who have been at Mount Everest, amateur athletes, cancer survivors, to people who have been sedentary their entire lives.

These are the knowledge, experience, and passion I use to help my clients achieve their goals.

The Why

Making the effort count—that's the why behind App Instructor JP.

Having trained for over 25 years, I know exactly what it means to give everything you have and still not see results. This motivated me to study the field, to finally be able translate effort into success.

Throughout my years as a resistance training instructor, I've met thousands of people, worked in dozens of gyms and homes. I've seen so many people with so much desire and drive to improve but that still fail to reach their goals simply because they lack the necessary tools.

This usually leads to uncertainty, disbelief, and hopelessness in those who have tried everything, and that breaks my heart. To make professional tools accessible to everyone, that's why App Instructor JP exists.

The Goal

To provide professional tools for everyday people.

Simply giving people everything they need to achieve their physical goals.

The Preparation

I've been building the databases by hand since 2009, week by week, year by year.

Since 2010, I began constructing body composition progress projection equations for my clients.

In February 2020, I officially started the first phases of what is now App Instructor JP. I began building caloric calculation tools in Excel, allowing diet adjustments based on daily caloric expenditure, as well as training program construction based on the biomechanical properties of each movement (which is why I built every anatomical and biomechanical aspect of each exercise).

Field Testing

Bodybuilding and Laboratory Tests

To verify the software tools, concepts, and mathematical formulas, I decided to start competing in bodybuilding—but not in the traditional way. Instead, I documented everything with DXA scans, doping tests, hormone panels, lipid profiles, and other laboratory tests required for scientific and impartial verification.

These lab results are available on my social media and include over 17 DXA scans, 28 blood tests, 9 doping tests, and thousands of daily photographs.

To effectively put my tools to the test, I decided to gain between 15 to 20 kilograms of fat and lose it all again on two separate occasions (2020 and 2021), publicly documenting the process with lab tests, videos, photos, and of course, bodybuilding competitions.

These tests allowed me to demonstrate not only that it's possible to compete in bodybuilding naturally (my best result so far is second place), but that I could project every kilogram of fat gained and lost with my tools, achieving deliberate and precise control over body composition.

With Clients

Since 2020, I've been using the tools I built based on known scientific principles combined with my own formulas and algorithms for creating diets, routines, and body composition projections with my clients.

Because of this, I've been able to dramatically increase my clients' success rate, and although they certainly have to do their part to follow the protocols, the results have been worth it.

Initially, I depended on manually creating the processes and documents required by my systems. However, this led me to learn the software programming necessary to automate the process—not only to scale but to increase precision even further.

Current Use

Real-time precise diets based on heart rate

Today, approximately 30 seconds after their heart rate session ends, my clients automatically receive diet adjustments on their phones.

This integration enables one thing: making the effort count. Since most diets are static, it's impossible to know if we're consuming the actual amount of calories and nutrients required, and since these change everyday a tool like this is required.

This software capability wouldn't have been possible without the knowledge I gained from Harvard's CS50X course and the daily Python programming I've done since December 31, 2024, when I completed the course.

Professional workout programming within everyone's reach

Thanks to the documentation I've created of all primary and secondary/synergist joint movements, muscle activation, required stabilization, bones involved, and movement patterns—along with many other properties of each exercise—combined with my ability to program in Python, I've integrated the algorithms and parameters I developed over the years for my clients based on NSCA principles and my professional experience. I was finally able to create the software tools and programs that allow for excellent routine creation based on each client's specific parameters, such as training level, available equipment, injuries, and goals ranging from coordination to strength, weight loss, muscle gain, and more.

Ongoing Development

My clients currently use these tools, including the routine builder logic, real metabolism-based diets, program downloads, real-time exercise comparison, and nutritionally similar food alternatives finder.

For 8 months I've been using my own beta applications, and as of 2026 I'm building the public versions, some of which are ready and under review.

Results

Ultimately, this translates to giving users fast, easy-to-understand, and immediately applicable tools with everything required to achieve their physical goals.
