Butt Kicks — Sprinting

Quick Intro

Butt kicks, sprinting, is a high-impact cardio exercise performed by driving the heel rapidly to the glute at sprint speed. The pace turns a warm-up drill into speed work.

Equipment Needed

Butt kicks, sprinting, only needs a stretch of open, flat ground to travel across.

Why Butt Kicks — Sprinting Matters

Speed is the main demand of this exercise, which is meant to be performed at sprint pace, well above the tempo of the basic drill.

The back of the thigh (biceps femoris and semitendinosus) pulls the heel up rapidly on every rep, the glutes (gluteus maximus) extend the hip through ground contact, the calves (gastrocnemius) manage the quick ground contact and the hip flexors (iliopsoas) reset the leg for the next cycle.

When to Do It

Butt kicks, sprinting, works well as a sprint-speed running-mechanics drill, a track and field warm-up component or a hamstring-activation primer before a hard running session, two to three times a week given the high impact and speed demand. Speed exposes technical gaps this drill’s slower version can hide.

Prioritizing knee height over heel recovery speed. At sprint speed the quick heel snap matters more than how high the knee travels forward, so chasing height alone misses the point of this version.
Existing hamstring sensitivity. The rapid heel pull places repeated demand on the hamstrings at speed. Building up through the slower Butt Kicks version first is worth doing if the hamstrings feel tight beforehand.
Attempting sprint speed before the basic pattern is smooth. A rushed, uncoordinated version at speed teaches poor mechanics quickly. Comfort with the drill at a moderate pace first pays off before adding full sprint effort.

A hamstring that’s already sensitive is the one item on that list worth resolving before adding sprint speed to this pattern.

Getting Ready

A few minutes of easy jogging or Butt Kicks at a moderate pace rehearses the basic heel-to-glute pattern before adding sprint speed.

Keep the torso tall and drive the arms hard while snapping the heel to the glute rapidly. At sprint speed this becomes a running-mechanics drill, so prioritize quick heel recovery over how high the knee travels forward.

Step-by-Step Instructions

1. Starting position. Stand tall with feet hip-width apart, arms bent and ready to drive.

2. The drive. Begin moving forward at speed, driving the arms hard.

3. The kick. Snap the heel of the trailing leg rapidly up toward the glute on every stride.

4. The rhythm. Continue the rapid heel-to-glute cycle at sprint pace, staying tall through the torso throughout.

How Many, How Often

Level	Where you’re at	What to do
Beginner	Comfortable with Butt Kicks at a moderate pace	4 sets of 10 meters at a quick but controlled pace, walking back to the start between sets.
Intermediate	The heel snap feels fast and consistent	4 to 5 sets of 15 to 20 meters, adding sprint effort while holding the pattern together.
Advanced	The pattern holds at full sprint speed	5 to 6 sets of 20 to 25 meters at true sprint pace, treating this as a speed-mechanics drill rather than one to keep loading further.

Keeping the heel recovery quick matters more here than knee height, since a slow heel snap at sprint pace undoes the technical benefit this drill is built around.

Modifications and Variations

Butt kicks, sprinting, sits between an easier, slower version and a harder full-speed application.

For an easier entry point, Butt Kicks covers the same heel-to-glute pattern at a slower, more controlled pace.

For more difficulty, Sprinting removes the exaggerated heel kick and applies the same sprint-speed mechanics to a full running stride.

Progression path: Butt Kicks → Butt Kicks — Sprinting → Sprinting

Build consistency with the slower version before adding full sprint speed, since a rushed pattern at speed teaches poor mechanics quickly.

Common Mistakes to Avoid

Prioritizing knee height over heel speed. It’s the exact technical breakdown that shows up once true sprint pace is added. Focusing on a quick heel snap over knee height fixes it and restores the drill’s purpose.

Leaning too far forward or backward. A torso that isn’t tall and stable throws off the timing of the rapid heel cycle. Staying tall through the torso keeps the pattern controlled at speed.

Letting the arm drive go passive. Passive arms slow the whole rhythm down at a pace where arm drive matters more than usual. Driving the arms hard keeps the tempo where it needs to be.

Jumping straight to sprint speed without the slower version feeling smooth first. Adding speed to a pattern that isn’t consistent yet compounds the inconsistency instead of building on it. Spending time on Butt Kicks at a moderate pace first pays off more than rushing into the sprint version.

After Your Set

Lying on the back and holding one straight leg up with both hands laced behind the thigh, gently pulling it closer to the chest, stretches the hamstring that pulled the heel up rapidly on every rep. Kneeling in a half-kneeling stance with the back foot propped flat against a wall behind, easing the hips gently forward, releases the hip flexor that reset the leg for the next cycle.

Going Deeper

A quick heel is doing more here than a fast pair of feet. Snapping the heel up rapidly trains the hamstring’s ability to shorten fast, which is exactly the quality that limits top running speed, while a heel that travels up slowly even at a fast forward pace mostly just tires the legs without building that specific quality. Chasing heel speed on every rep, ahead of how far each stride covers, gets far more sprint-mechanics value out of the same distance.

Someone already comfortable with Butt Kicks can typically manage 4 sets of 10 meters with a quick heel snap within their first two to three sessions. 5 sets of 20 meters at true sprint pace tends to arrive somewhere in the four to six week range.

How to Know You’re Improving

Four checkpoints separate a heel snap that’s still catching up to sprint speed from one that’s there.

4 sets of 10 meters with a consistently rapid heel-to-glute snap
A torso that stays tall through the whole set rather than leaning
An arm drive that stays active and matched to the leg tempo
A comfortable jump to sprint speed without the heel snap slowing down

A heel that snaps up quickly through a full sprint effort, not distance covered, is what progress looks like here.

Muscles Worked

Biceps Femoris (the outer hamstring at the back of the thigh, snapping the heel up at sprint speed)
Semitendinosus (the inner hamstring muscle at the back of the thigh, matching the outer hamstring’s fast knee bend)
Gluteus Maximus (the largest glute muscle, driving the body forward while the heels keep cycling)
Gastrocnemius (the main calf muscle, producing a short sharp ground contact between kicks)
Iliopsoas (the muscle group at the front of the hip, bringing the thigh through at speed)

FAQ

How is this different from the regular butt kick drill? Butt Kicks covers the same pattern at a slower, more controlled pace, and it’s worth building solidly before adding true sprint speed.

Why does my hamstring feel worked more here than in regular sprinting? The exaggerated heel-to-glute range at speed places repeated demand specifically on the hamstring’s ability to shorten fast, more than a standard sprint stride does.

Do I need to master the slower version first? Yes. Attempting sprint speed before the basic pattern is smooth teaches poor mechanics quickly and makes them harder to unlearn later.

Is there a harder progression after this? Yes. Sprinting applies the same sprint-speed mechanics to a full running stride once the heel-snap pattern holds together consistently.
