HYROX ENGINE – Transitioning Strength Athletes into Strong Runners

HYROX ENGINE is a year-round training system for athletes with a strength background, CrossFitters, weightlifters, or functional fitness athletes, who want to build their engine, improve running, and become more resilient over longer efforts. It’s a structured, science-backed progression designed to close the gap between strength and endurance.

We get you ready for your next HYROX race, whether that’s in 3 months or 12.

What’s Inside the Weekly Structure:

✅ 3x Conditioning Sessions

– 2x Running: a mix of intervals and low-intensity Zone 2 work

– 1x Long Zone 2 Endurance: focused aerobic work on the ergs (row, bike, ski, etc.)

✅ 2x Functional HYROX Workouts

– Simulate race-specific demands: wall balls, sleds, burpees, lunges, and transitions under fatigue

✅ 1x Strength Session

– Structural strength: compound lifts with higher reps at moderate loads to maintain strength and support running mechanics

**Overall number of conditioning/hyrox or strength sessions can increase/decrease depending on the block we are in.

Block Periodization: Built to Progress Over Time

The program runs in 8–12 week training blocks:

🟫 Block 1: Linear Build-Up

Build a strong foundation with compound movements and movement quality. Introduce low-impact conditioning and Zone 2 running volume gradually.

🟩 Block 2: Higher Volume

Increase total running / conditioning volume and aerobic capacity while continuing functional and strength maintenance.

🟥 Block 3: Competition Prep

Simulate full-race efforts, sharpen transitions, peak conditioning, and taper. Dial in pacing and strategy for race day execution.

You can join the program at any point. We provide a free taper and race-prep week that you can use at any phase of the training cycle

What to Expect:

✅ 5-6 Purpose-Driven Training Days per Week

✅ A year-round training plan with two Peak Phases per year – One in the Spring and one in the late Fall according to the bulk of the HYROX season

✅ Coach Access via Discord – Ask questions, get support, and connect with other serious athletes

✅ Montly live Q&A with founder Gommaar D'Hulst on YouTube

Programming Philosophy

We do not pretend to have all the answers when it comes to HYROX coaching and programming. The sport is still new, and many key questions remain: should you run a lot, focus on HYROX-specific workouts, train more low intensity or high intensity?

That is exactly why we tested these questions ourselves in a HYROX-specific 10-week training study. We combine those insights with data from our previous HYBRID 1.0, HYBRID 2.0, and Zone 2 (CrossFit-specific) projects to design training progressions that are not only effective, but also practical and engaging. A year-round training plan crafted from combining a science-based approach with years of coaching experience.

What Equipment Do You Need?

To get the most out of HX ENGINE, you should have access to an equipped functional fitness facility. Here's what you'll need:

• Barbell + bumper plates
• Dumbbells and/or kettlebells
• Wall ball
• RowErg, BikeErg, SkiErg (Runner optional)
• Sleds (for off-season and odd-object work)
• Boxes, rings, pull-up bar, and other standard gymnastics tools

Training in a limited setting? No problem. We provide smart substitution options so you can still follow the program with intensity and intent. The coaches available via discord can support you in this.

Why Athletes Choose HX ENGINE

Our approach combines the science of training with the art of programming.

Athletes initially choose our programs out of curiosity; wanting to see what a more data-driven approach can do for their training. They stay because they see real progress and break through performance plateaus. A key feature often overlooked in other programs is the meticulous monitoring of training load - in other words, the stress each session places on the body and how well you recover from it. We take great care to track and adjust training load intelligently, reducing injury risk and supporting long-term progression.
