Search "running form" and you will drown in slow-motion videos and conflicting advice about foot strike. Here is the truth: your body already mostly knows how to run. You need three small adjustments, not a rebuild.

1. Run tall The single highest-value cue is posture. Imagine a string gently pulling the top of your head toward the sky. Stand tall, lean very slightly forward from the ankles, not the waist. This opens your chest, lets you breathe, and stops the hunched shuffle that wrecks beginners' backs and necks.

2. Shorten your stride The most common beginner mistake is overstriding, reaching the foot way out in front of the body. This acts like a brake with every step and slams force into your knees. Instead, take quicker, smaller steps and aim to land with your foot under your hips. Think "light and quick" rather than "long and powerful."

3. Relax your hands and shoulders New runners clench. Shoulders creep up toward the ears, fists ball up, and all that tension burns energy and tightens your stride. Drop your shoulders. Imagine holding a potato chip in each hand that you must not crush. Let your arms swing forward and back, not across your body.

Stop obsessing over foot strike Heel, midfoot, forefoot: for a beginner running easy, it genuinely does not matter much, and trying to force a landing usually causes injury. Run tall, take short quick steps, stay relaxed, and your feet will sort themselves out. Form is something you nudge over months, not something you fix in a day. Get these three right and the rest follows.
