Coaching for anyone done drifting

You don't drift
into shape. You build it.

thebuildsystem is a physique & mindset coaching system built by a guy who rebuilt himself first — from a mental low in 2020 to a remote valley in Australia to Hyrox. Training, food and head-space, run as one system, for anyone in their mid-20s who's done coasting.

The method

Three systems. Run together.

Most programs hand you a PDF and disappear. thebuildsystem runs training, nutrition and mindset as one loop — because a routine that ignores your head and your plate doesn't hold past week three.

Training

Progressive strength and conditioning blocks, built around your equipment and schedule — not a generic 12-week template.

Nutrition

Meal-by-meal calorie targets across three intensity levels, sport-nutrition style — with one guilt-free meal built in every weekend.

Mind

The part most coaches skip. Daily structure, journaling and check-ins for the fear-of-failure and no-motivation days — the ones that actually decide the outcome.

The founder

From a low point to the Hyrox start line

I started training in 2020 to climb out of a mental low point — not to build a brand. Everything since has been the same system, applied to myself first.

2020

Training as a way out

Picked up training to get out of a mental low — no plan, no coach, just consistency and paying attention to what actually worked.

2023

Moved to Australia

Three years of physical work — bar work, moving houses, gardening, framing, hotel maintenance, events — while training kept running underneath it all, based out of Manly.

2024

The sharpest transformation

A stretch of time in an isolated valley, working with horses, journaling daily and training almost every day produced the biggest physical and mental shift of the whole process — and became the blueprint for the system.

2026

Hyrox, then home

Closed the Australia chapter by racing Hyrox, then moved back to Argentina to build thebuildsystem full-time — turning the process into a system other people could actually run.

Running Club

Running clears the head. Then it builds the engine.

Every session starts the same way — legs moving, head quiet. It's the cheapest test of discipline I know, and the aerobic base everything else in training sits on.

Running Club

Clears the head

No shortcuts, no one to perform for — just pace and whether you hold it.

Builds the engine

A stronger aerobic base means faster recovery and more capacity in every other session.

Free tool

Get your VAM

VAM (Maximal Aerobic Speed) is the pace where your aerobic engine caps out. Warm up, then run 5 minutes at the hardest pace you can hold — steady, not a sprint. Enter how far you got and get your number instantly.

Max-effort test — if you're new to running or have a health condition, check with a doctor first.

An 18-day in-person camp in Bali, built into a 6-week program

Yesenia brought the idea herself: instead of a remote plan, hire a personal trainer for a dedicated block. So we built an 18-day in-person camp in Bali — three phases of strength, cardio and recovery, planned day by day — as the opening stretch of a 6-week program built around her goal.

6 months of strength training and running

Estanislao plays rugby and came in wanting to add muscle without losing his engine. Three months of strength training paired with running took him from 63kg to 66kg — the opening stretch of a 6-month program built to keep adding mass while he keeps playing.

Camp

Some training happens somewhere else

A few times a year I take this on the road — pick a place, block off real time, and run intensive in-person sessions there. Same system, built into a fixed block, somewhere else for a while.
