1. Overstriding
If your foot lands far in front of your hip, every step acts like a brake — and the impact travels straight up to your knee. The fix: shorten your stride and aim for a cadence of 170-180 steps per minute. Most beginners run at 150-160. Use a metronome app set to 175 bpm and match your steps to the beat.
2. Heel Striking Hard
Landing hard on your heel sends a shock wave up through the tibia and into the knee joint. You don't need to switch to forefoot striking — just aim to land softer and closer under your hip. Run on a treadmill barefoot for 60 seconds: your body will naturally find a quieter, more efficient landing pattern.
3. Crossing the Midline
Watch yourself in a mirror or on video — if your feet cross over your body's centerline, the rotational stress lands on your knees and hips. Cause is usually weak glute medius. Fix: add 2 sets of 12 banded clamshells and 2 sets of 10 single-leg glute bridges to your warm-up.
4. Slouched Upper Body
Looking down at your feet collapses your chest and tilts your hips backward, forcing your knees to absorb more force. Cue: 'tall through the crown of the head, gaze 20 meters ahead.' Imagine a string pulling the top of your head toward the sky.
5. Death-Grip Hands
Tense hands and clenched fists create tension that travels up your arms, into your shoulders, and down through your hips. Run with thumbs lightly resting on index fingers, as if holding a potato chip you don't want to break. The whole body relaxes, stride lengthens, knee load drops.
