Bilateral Training

Bilateral training involves exercises where both limbs work together at the same time - back squats, conventional deadlifts, barbell bench press, and pull-ups are classic examples. Because both sides share the load, bilateral movements allow you to lift heavier weights than any single-limb variation, making them the cornerstone of maximal strength development. For HYROX^® athletes, that raw strength is the engine behind Sled Push, Sled Pull, and every running stride.

Why It Matters for HYROX^®

The Sled Push station alone demands that you move 152-202 kg (women/men) across 50 metres as fast as possible. That is a bilateral effort - both legs driving simultaneously against the ground. The stronger your squat and deadlift, the easier that sled moves. There is no substitute for the absolute force production that heavy bilateral training builds.

Bilateral exercises also develop the posterior chain as a coordinated unit. The deadlift pattern - hip hinge with both feet planted - transfers directly to the initial pull phase of the Sled Pull and the hip extension required to maintain running speed when fatigued.

From a hormonal and neuromuscular standpoint, heavy bilateral lifts recruit the most motor units and trigger the greatest systemic training response. This means more muscle, stronger tendons, and a more resilient body that can absorb the punishment of an 80-minute race. Research directly comparing bilateral, unilateral, and hybrid resistance training protocols confirms that bilateral training produces significant improvements in overall strength, though unilateral methods offer additional advantages for non-dominant limb development.^[1]

How to Apply It

Structure two to three bilateral strength sessions per week during the general preparation phase. Prioritise the squat, deadlift, and overhead press as your primary lifts. Use a progressive overload model: add 1-2.5 kg per week or increase reps before adding weight.

During HYROX^®-specific phases, shift toward moderate loads at higher rep ranges (3-4 sets of 8-12) to build strength-endurance that mirrors station demands. For example, performing 4 sets of 10 back squats at 65-70% of your one-rep max conditions the quads for sustained effort under load.

Pair bilateral lifts with HYROX^® station drills in the same session. A back squat followed immediately by a 50-metre Sled Push teaches your body to produce force when pre-fatigued - exactly what race day demands.

Key Guidelines

• Primary lifts: Back Squat, Deadlift, Bench Press, Overhead Press, Barbell Row.
• Strength phase: 3-5 sets of 3-6 reps at 80-90% 1RM, 2-3 minutes rest.
• Strength-endurance phase: 3-4 sets of 8-12 reps at 60-75% 1RM, 60-90 seconds rest.
• Frequency: 2-3 bilateral sessions per week, balanced with unilateral accessory work.
• Track progress: Log loads and reps weekly; aim for measurable improvement every 3-4 weeks.

Frequently Asked Questions

Should HYROX^® athletes prioritise bilateral or unilateral training?

Both. Bilateral training builds the raw strength and power needed for heavy stations like Sled Push and Sled Pull, while unilateral training addresses imbalances and running-specific stability. A well-designed programme includes both in every training week.

How heavy should HYROX^® athletes squat?

There is no universal target, but a good benchmark is 1.5x bodyweight for a back squat. At that level, the Sled Push and Wall Ball stations become significantly less taxing, freeing energy for the running segments.
