HRXperformance backed by science

BACKED BY RESEARCH
The science behind every product

Every HRX Performance product is built on more than race-day intuition. The claims we make about stability, recovery and performance are backed by peer-reviewed research — so you can train and race with confidence in what you're wearing and following.

COMPRESSION KNEE SLEEVE

Stability that holds when your legs are already gone

The 200m walking lunges arrive at the worst possible moment — after kilometers of running and seven stations of accumulated fatigue. That's exactly when the knee's ability to sense its own position starts to break down.

A systematic review of 20 studies found that knee sleeves measurably improve proprioception in healthy knees and deliver functional improvement in injured ones. [1] Research specifically on hop and cutting movements — the same mechanics as weighted lunges under load — showed that wearing a knee sleeve significantly reduced average ACL loading rates, lowering injury risk at the exact moment fatigue hits hardest. [2] A further study confirmed that a neoprene knee sleeve compensates for the loss of knee position sense that occurs as muscles fatigue [3] — which is why it's not just useful on race day, but on every hard training session leading up to it.

The compression also improves blood flow during effort, supporting faster clearance of metabolic waste — which means less soreness, less swelling and a shorter gap between sessions.

What the research confirms:

• Improved proprioception under fatigue

• Reduced ACL load during lunges and hops

• Faster recovery between sessions

COMPRESSION SHOULDER SLEEVE

Keep your shoulder in the race from station one to station eight

The SkiErg, sled push, burpee broad jumps, farmer's carry — every station loads the shoulder. By station five, most athletes feel it. By station eight, it's all they can think about. The shoulder is the most mobile joint in the body, which makes it the most vulnerable under repeated high-rep loading.

Research shows that a neoprene shoulder sleeve measurably improves active joint repositioning — the ability of your shoulder to find and hold the correct position — in both stable and unstable shoulders. [4] Compression garments applied to the shoulder and scapular area improve both active and passive joint repositioning, with researchers attributing the effect to increased proprioceptive feedback through skin contact. [5]

A 2024 systematic review and meta-analysis — the most comprehensive to date — confirmed that compression garments consistently deliver significant proprioceptive improvements across multiple studies compared to no garment. [6] That translates directly to less compensatory movement, reduced rotator cuff stress and a shoulder that can keep up with the demands of a full HYROX race.

What the research confirms:

• Better joint position sense under load

• Less rotator cuff compensation

• Confirmed by 2024 meta-analysis

HYROX TRAINING PROGRAMS — BEGINNER, INTERMEDIATE & ADVANCED

Built around what the data actually says about HYROX performance

Most HYROX athletes train hard. Fewer train smart. The difference shows up on race day — in blown pacing, station technique that falls apart under fatigue and recovery that doesn't keep up with training load. Our programs are designed specifically to close those gaps.

The first peer-reviewed physiological study of HYROX (Frontiers in Physiology, 2025) found that faster finish times were significantly correlated with higher VO₂max and structured aerobic training. [7] That's why aerobic base building and compromised running sessions — running under accumulated fatigue — sit at the core of every program level, from beginner to advanced.

A 2025 athlete profile study found that recovery strategies among HYROX competitors were frequently unstructured or insufficient, directly increasing injury risk and limiting performance consistency. [8] Every HRX program — whether it's the 8-week beginner plan or the 12-week advanced block — includes explicit recovery protocols and progressive loading so you arrive at the start line ready to race, not just ready to survive.

What the research confirms:

• VO₂max and aerobic base as performance foundation

• Structured recovery built into every week

• 3 levels: beginner through advanced
