High Knees
Running in place with high knee drive — heart rate booster and hip flexor primer.
Execution
- Stand tall, arms at boxer angle.
- Alternate driving the knees up to hip height (or higher) at a fast pace.
- Land on the balls of the feet, springy and quiet.
- Stay upright — don't lean forward to "meet" the knees.
Tips
- Great cardio burst between sets (30-60 s) — no gear, plenty of stimulus.
- If the knees don't come up, it's jogging in place — not the exercise.
Heart rate up, hip flexors active
High knees are running in place with an exaggerated knee drive. They push the heart rate up quickly while activating the hip flexors — a muscle group that gets shortened by sitting but is rarely actually strong.
Their real value lies in warming up before running and jumping sessions: they prime exactly the movement pattern needed afterward, at a higher frequency than an easy steady run.
Execution
Stand tall, then alternate driving the knees up to hip height. Ground contact is brief and over the balls of the feet, the heels barely come down. The torso stays upright — it must not lean back to make the knees look higher.
The arms drive opposite to the legs, as in a sprint.
Common mistakes
- Leaning back. The most common mistake. It fakes knee height and strains the lower back.
- Landing on the heels. Loud, hard and slow. Contact belongs on the balls of the feet.
- Knees too low. Below hip height it turns into jogging in place without the actual stimulus.
Programming
In the warm-up: two to three rounds of 20 seconds. As a conditioning element: 30 to 45 seconds with an equal rest, six to eight rounds.
