Obliques
The internal and external oblique muscles on the sides of the torso. They resist rotation and lateral flexion — stabilizing the trunk during one-shoulder Sandbag Lunges, preventing lateral sway in Farmers Carry, and controlling rotation while running.
Definition
Obliques are one of the most HYROX®-relevant muscle groups in the body. The internal and external oblique muscles on the sides of the torso. They resist rotation and lateral flexion - stabilizing the trunk during one-shoulder Sandbag Lunges, preventing lateral sway in Farmers Carry, and controlling rotation while running.
Why Obliques Matter for HYROX®
Weak obliques cause trunk collapse during one-shoulder Sandbag Lunges and uneven Farmers Carry gait. The body tilts toward the load, wasting energy on correction rather than forward movement. This adds 10-20 seconds to both stations.
| HYROX® Station | Role of Obliques |
|---|---|
| Sandbag Lunges (100m) | The offset sandbag on one shoulder creates lateral force the obliques must resist for 100m. |
| Farmers Carry (200m) | Obliques prevent lateral sway while carrying heavy loads for 200m. |
| Running (8km total) | Obliques control trunk rotation on every running stride. |
| SkiErg (1,000m) | Obliques stabilize the trunk during the bilateral pull-down pattern. |
Best Exercises to Build Obliques
These exercises come from the ROXBASE exercise database of 217 movements, prioritized by transfer to HYROX® race performance.
- Pallof Press - The gold standard anti-rotation exercise. 3 sets of 10 per side with a cable or band.
- Side Plank - Anti-lateral flexion endurance. Hold 30-45 seconds per side for 3 sets.
- Dumbbell Suitcase Carry - Single-side loaded carry that forces obliques to maintain vertical posture. 3 sets of 40m per side.
- Russian Twists with Wall Ball - Controlled rotation with load. 3 sets of 10 per side - don't rush.
- Renegade Row - Anti-rotation row from push-up position. 3 sets of 8 per side.
- Kettlebell Halo - Circular shoulder movement that challenges oblique stability. 3 sets of 8 per direction.
Training Recommendations
Train obliques through ANTI-rotation and anti-lateral flexion, not twisting. 2-3x per week: Pallof Press (3×10/side), Side Planks (3×30-45s/side), and Suitcase Carries (3×40m/side). Add Russian Twists sparingly - controlled rotation, not speed, is the goal.
FAQ
Why do obliques matter for Sandbag Lunges?
The sandbag sits on ONE shoulder, creating an asymmetric load that tries to pull you sideways on every step. Your obliques resist this lateral force for 100m of lunges. Weak obliques mean a wobbly, energy-wasting lunge pattern. Strong obliques keep you upright and efficient.
Are Russian Twists good for HYROX®?
In moderation. The primary oblique demand in HYROX® is anti-rotation (resisting force), not generating rotation. Pallof Presses and Side Planks are more specific. Use Russian Twists occasionally for variety, but keep them controlled - no ballistic twisting.
Your obliques don't train themselves - and generic gym programs rarely target them for the endurance HYROX® demands. ROXBASE analyzes your race data to find which muscles are holding you back, then builds station-specific training that targets your weaknesses. Find Your Weak Station →
