HYROX demands a rare combination of endurance and functional strength. Athletes need to run 8 km, but between every kilometre they face a station that punishes anyone who hasn't trained their strength intelligently.

The question most HYROX athletes face isn't whether to strength train, but how to train smart enough that they're getting stronger, increasing their power endurance without accumulating unnecessary fatigue that compromises their conditioning work.

This is exactly where Velocity-Based Training (VBT) comes in.

Velocity-Based Training uses real-time movement speed data to guide your training decisions. Rather than relying solely on percentages of a one-rep max (1RM) or subjective effort scales like RPE, VBT gives you an objective measure of how your body is performing on any given day.

With the Output sensor, every rep you perform is tracked. The speed at which you move a load tells you, and your coach, exactly what training zone you're working in and whether you're fresh, fatigued, or right on target. Focus on increasing your power endurance, to maintain intensity throughout the race.

HYROX training requires balancing high-volume conditioning alongside meaningful strength work. Overloading in the gym means fatigued running sessions, slower recoveries, and a higher risk of injury. VBT lets you autoregulate your training in real time, if your bar speed drops below your normal range at a given load, you know to dial it back. If you're moving faster than expected, you can push with confidence.

This removes the guesswork. Every set becomes an informed decision, with the Capture app giving you real time feedback, maximizing strength and power improvements without pushing beyond your limits.

Traditional 1RM testing is fatiguing and time-consuming, two things HYROX athletes can't afford during a training block. With Output's Load-Velocity Profiling (LVP), you can estimate your 1RM and build a complete strength profile from your regular training sets. You simply need data across a spread of loads (light, moderate, and heavy), and Output generates your profile automatically.

This means you get the insight of a full strength assessment without the recovery cost.

A load-velocity profile does more than estimate your max. It reveals whether an athlete is a velocity-dominant or strength-dominant athlete. A HYROX athlete who moves lighter loads explosively but has a relatively low 1RM is likely velocity-dominant, great for wall balls and burpee broad jumps, but potentially undertrained for sled pushes at heavier competition loads. The reverse is also true: a strong athlete with poor velocity at lighter loads may fatigue faster through high-rep stations.

Understanding where you sit on this spectrum lets you (or your coach) target the specific qualities that will have the biggest impact on race day.

With Output's LVP autoregulation feature, your load-velocity profile updates automatically. Every training session contributes to a rolling picture of your performance. You don't need to schedule separate testing blocks, your training is your testing.

This is especially valuable for HYROX athletes who are juggling multiple training modalities and can't sacrifice sessions for assessments.

One of the biggest challenges in HYROX preparation is maintaining training intensity across a high volume of sessions. VBT gives athletes immediate, objective feedback on every rep.

The Output Capture app shows whether you're lifting above, below, or within your normal velocity range for a given load. This turns each set into a small competition with yourself, driving maximal intent without relying on a coach standing over your shoulder for every rep.

Every rep has a purpose, with the right intent, you will increase power output, transferring to race day.

Once you upgrade to HYROX x Output Sports Elite (Request Demo) or are a direct Output Sports customer, getting started with VBT for your HYROX training is straightforward:

Your profile recalculates each morning using a rolling six-week window, so it always reflects your current capabilities rather than an outdated test result.

● Sled push/pull preparation - Use LVP to find the right training loads that build strength without excessive fatigue. Monitor velocity to ensure you're training with enough intent to build the power needed for competition loads.

● Wall balls and lunges - Track velocity at lighter loads to ensure you're developing the muscular endurance and speed that these high-rep stations demand.

● Periodisation across a training block - Use your profile to shift training emphasis from general strength to power and speed-strength as race day approaches, all guided by objective data.

● Daily readiness checks - If your velocity is significantly below baseline on a given day, it may be a signal to reduce load or volume to protect your conditioning sessions later in the week.

If you're already using Output for VBT, you can begin building your load-velocity profile from your existing training data today. For a step-by-step walkthrough, see our guide on How to Create a Load-Velocity Profile.
