High Knees

How to do it

Stand tall with feet hip width apart and arms bent at roughly ninety degrees, ready to drive.
Run in place, driving each knee up toward hip height in quick alternating fashion.
Pump the arms in opposition to the legs to help maintain rhythm and balance.
Land on the balls of the feet each time, letting the quadriceps and hip flexors control the quick knee drive.
Keep the torso upright and avoid leaning back, which shortens the range of the knee drive.
Maintain a fast, consistent cadence and avoid letting the knees drift only partway up, a common fault that reduces the working range for the quadriceps and biceps femoris.
