Butt Kicks

Definition

Butt kicks are a cardio-pattern running drill where you jog forward while rapidly driving your heels up toward your glutes. This dynamic warm-up exercise develops hamstring activation, running cadence, and ankle dorsiflexion - essential running mechanics for HYROX^® athletes.

Technique & Form

1. Starting position: Stand tall with feet hip-width apart, arms relaxed.
2. Run: Begin jogging forward at a moderate pace. Drive each heel up toward your glute as quickly as possible.
3. Contact: The heel should lightly tap or come close to your glutes on each stride. Keep the knee pointing down - this is not a high-knee drill.
4. Arms: Pump arms naturally at 90 degrees in coordination with the opposite leg.
5. Breathing: Breathe rhythmically. Cover 20-40 metres per set. Perform 3-4 sets.

Muscles Worked

• Primary movers: Hamstrings, hip flexors
• Secondary: Glutes, calves, quadriceps
• Stabilizers: Core, ankle stabilizers

Common Mistakes

1. Lifting the knees too high: Keep knees pointing down. The motion comes from the hamstring pulling the heel up, not hip flexion.
2. Leaning too far forward: Maintain an upright posture with a slight forward lean from the ankles.
3. Moving too slowly: The drill should be performed at a moderate jog with rapid heel contact.

Benefits

Butt kicks activate the hamstrings and improve the recovery phase of the running gait cycle. They increase running cadence and prepare the legs for higher-intensity running.

HYROX^® Context

As a running drill, butt kicks support the 8 km of running in HYROX^® by improving hamstring activation and running mechanics. Include them in every warm-up: 3-4 sets of 30 metres after a light jog, before progressing to B-skips and strides.

Variations & Alternatives

• B-Skips - More advanced drill with pawing extension.
• Carioca - Lateral drill for hip mobility.
• Bodyweight Calf Raise - Ankle strength for running propulsion.

FAQ

When should I do butt kicks? During your running warm-up, after 5 minutes of easy jogging. 3-4 sets of 20-30 metres.

Do butt kicks improve running speed? They improve cadence and hamstring activation, which contribute to faster turnover and running economy.
