Roncevic's 9-Move Strength Session He Never Skips

Roncevic's 9-Move Strength Session He Never Skips

When Alex Roncevic crossed the HYROX finish line in under 52 minutes, he didn't just break a world record. He redefined what the human body can do across eight functional stations and 8 kilometers of running. That kind of performance doesn't happen by accident, and it doesn't happen without a strength foundation built to last.

Roncevic's weekly strength session is nine moves. That's it. No sprawling three-hour gym blocks, no random exercise selection. Every movement earns its place by targeting the exact muscle groups and patterns that determine how fast you move through a HYROX course. Here's what that session looks like, why each exercise is in there, and how you can adapt it regardless of your age group.

Why Strength Training Is Non-Negotiable in HYROX

HYROX is not just a running race with obstacles. It's a precision test of your ability to sustain output across repeated transitions between aerobic effort and functional power. The moment your posterior chain fatigues on sled pushes, your running economy on the next kilometer collapses. Strength and speed are not separate concerns here. They're the same concern.

The challenge most HYROX athletes face is managing strength training volume without accumulating fatigue that bleeds into their running sessions. High-mileage training weeks demand recovery. Adding heavy lifting on top of that without a structured approach leads to stagnation or injury. Roncevic's nine-move session is deliberately compact because it has to be. It's designed to build and maintain functional strength without creating the kind of systemic fatigue that slows you down on race day.

The 9-Move Session: Structure and Selection

The session follows a logical flow: posterior chain and hip power first, upper body pulling and pressing in the middle, and core plus loaded carry work at the end. That sequencing matters. It mirrors the muscular demand order you'll actually experience during a HYROX race.

Move 1: Trap Bar Deadlift

The foundation of the session. The trap bar deadlift builds total posterior chain strength, specifically the glutes, hamstrings, and erectors, while keeping spinal stress lower than a conventional barbell pull. For HYROX, strong posterior chain mechanics directly translate to sled push and sled pull efficiency. Roncevic works in the 3 to 5 rep range at high relative intensity, keeping neural output high without accumulating volume that creates soreness ahead of running sessions.

Move 2: Bulgarian Split Squat

Single-leg strength is one of the most under-trained qualities in endurance athletes, and it's directly relevant to running economy. Each running stride is a single-leg loading event. The Bulgarian split squat builds unilateral quad and glute strength while exposing and correcting asymmetries. For HYROX athletes carrying fatigue through later kilometers, those asymmetries are where time gets lost.

Move 3: Romanian Deadlift

A hamstring-specific complement to the trap bar deadlift. The Romanian deadlift targets the eccentric loading capacity of the hamstrings, which is the exact quality that protects you from injury when running at pace under fatigue. It also reinforces hip hinge mechanics that carry over to the sled push starting position and the burpee broad jump floor-to-stand transition.

Move 4: Weighted Pull-Up

Upper body pulling strength is directly tested in the HYROX rowing station and the ski erg. Weighted pull-ups build lat and scapular retractor strength in a vertical pulling pattern. Roncevic adds load gradually here, treating it as a long-term strength development movement rather than a conditioning tool. The goal is genuine strength, not exhaustion.

Move 5: Landmine Press

The landmine press is a shoulder-friendly pressing movement that builds anterior shoulder and upper chest strength in a pattern that mimics the pushing mechanics used during wall balls and the sled push finish position. It's easier on the rotator cuff than a strict overhead press, which matters when you're also logging significant running volume that creates residual upper body tension.

Move 6: Chest-Supported Dumbbell Row

Rowing stations in HYROX reward athletes who can sustain output through the mid-back and rear delts without form breakdown. The chest-supported row eliminates lower back compensation, isolating the pulling musculature directly. It pairs with the pull-up to create comprehensive horizontal and vertical pulling strength.

Move 7: Goblet Squat with Pause

This is the session's movement quality anchor. The goblet squat with a two-second pause at the bottom develops positional strength in the deep squat position, improves ankle and hip mobility under load, and reinforces the pattern needed for wall ball shots. The pause specifically builds the ability to generate force from a fully loaded position, which is exactly what wall balls demand at the bottom of each rep.

Move 8: Pallof Press

Anti-rotation core strength is one of the most overlooked qualities in endurance athletes, and it's one of the most relevant for HYROX. Every running stride, every sled push, every ski erg pull requires your core to resist rotational force rather than produce it. The Pallof press trains that quality directly. It's low fatigue, low injury risk, and high return on time invested.

Move 9: Farmer's Carry

The session closes with loaded carries. The farmer's carry taxes grip strength, shoulder stability, and core bracing simultaneously while adding a cardiovascular element that keeps the session honest without replacing conditioning work. It also mimics the sustained tension demands of carrying and transitioning between HYROX stations. Heavy carries at the end of a strength session, when you're already fatigued, are a specific adaptation stimulus you don't get from any other exercise.

How the Session Fits Into a Weekly Training Block

Roncevic runs this session once per week, placed 48 hours away from his hardest running session. That spacing isn't arbitrary. Research consistently shows that strength training within 24 hours of a high-intensity run compromises adaptation in both modalities. Giving each session its own recovery window lets both training stimuli land cleanly.

The session takes roughly 60 to 75 minutes depending on rest periods. Roncevic keeps rest intervals between 90 seconds and 3 minutes depending on the movement. Heavy compound lifts get the longer rest. Accessory work gets less. That structure preserves performance quality across all nine moves rather than turning the session into circuit-style conditioning, which would undercut the strength stimulus.

Fueling around this session also matters more than most athletes realize. If you're training at high volume, your ability to recover from a strength session is directly tied to your protein intake and overall energy availability.

Adapting the Routine for Age-Group Athletes

Most HYROX athletes aren't world record holders, and this session doesn't require you to be. The nine movements are selected for their transfer value, not their complexity. Here's how to scale them practically.

• Reduce load, not movement pattern. A 55-year-old athlete doing a bodyweight Bulgarian split squat is still building the same unilateral strength quality as Roncevic doing it with dumbbells. Keep the pattern, adjust the resistance.
• Extend rest periods if needed. Recovery capacity decreases with age. If 90-second rests leave you moving badly on the next set, take two to three minutes. Quality of execution matters more than session density.
• Prioritize the posterior chain and single-leg work. If you're short on time, moves one through three plus move two should be your non-negotiables. Those are the movements with the highest direct carry-over to HYROX station performance and running economy.
• Progress systematically. Add load in small increments, five to ten pounds on compound lifts across three to four weeks. HYROX prep is typically a six to twelve month process. Slow, consistent strength progress compounds significantly over that timeline.

Recovery quality also scales in importance as training volume increases.

What This Session Doesn't Include (And Why)

There's no bench press, no bicep curl, no leg extension, and no traditional back squat in this session. That's intentional. Roncevic's selection excludes movements that either duplicate existing stimulus, add unnecessary fatigue, or have low transfer value to HYROX performance. The back squat, for example, is a powerful strength builder, but it creates significantly more lower back and quad fatigue than the trap bar deadlift and Bulgarian split squat combination, without adding meaningfully different stimulus for this specific sport.

The session also excludes conditioning work entirely. That's not laziness. It's discipline. Conditioning is handled through running sessions and HYROX-specific station training. Mixing conditioning into the strength block would compromise both.

The Bigger Picture

A sub-52 HYROX finish requires running economy, station-specific power, and the ability to sustain both under fatigue for nearly an hour. Roncevic's nine-move session addresses all three by building a functional strength base that supports, rather than competes with, his running volume.

If you're preparing for your next HYROX race and wondering where to focus your limited training time, this session gives you a clear answer. Nine movements, executed with precision, once per week. That's the foundation. With events like the Stockholm Worlds Elite Doubles drawing the sport's top competitors, the training standards at the front of the field are rising. Matching the structure of a world record holder's strength work is one of the most direct ways to close the gap.

You don't need to train like a professional athlete. You need to train like someone who understands why each minute in the gym exists. That's what Roncevic's nine moves teach.
