A-Drill Marching
A-drill marching is a running-specific warm-up drill that teaches proper hip flexion mechanics while activating the hamstrings and hip flexors. The “A” position — knee driven high with the toe dorsiflexed — trains the muscle coordination pattern used in sprinting and fast walking.
Setup
- Stand tall with feet together and arms at your sides.
- Drive your right knee up toward the chest (aim for hip height), pulling the toes up toward the shin (dorsiflexion).
- As the right knee drives up, swing the left arm forward naturally (opposite arm, opposite leg).
- Strike the right foot back down to the ground directly under your hips with a quick, pawing motion.
- Immediately drive the left knee up and repeat.
- March forward for 10–15 yards, or perform 10–12 reps per leg in place.
Coaching Cues
What to feel:
- Hip flexors driving the knee up; hamstrings pulling the foot back down
- An upright, tall posture — do not lean back or forward
- The rhythm of opposite arm/opposite leg coordination
Common mistakes:
- Leaning backward to get the knee higher — stay tall and let the hip flexor do the work
- Pointing the toes instead of dorsiflexing — the “toe up” cue is critical for running mechanics
- Landing on the heel instead of the midfoot — the foot should paw backward, not stomp forward
Tip
Start with a slow, exaggerated march before progressing to a faster tempo. The goal is pattern quality first, speed second.

Programming
| Parameter | Recommendation |
|---|---|
| Reps | 10–12 per leg, or 2 x 15 yards |
| Sets | 2–3 |

Progressions
- Beginner: Slow march in place with wall support.
- Intermediate: Walking A-drill for distance at moderate tempo.
- Advanced: A-skip (add a small hop on the stance leg) for power and coordination.
