Knees not reaching hip height.
Losing hip position during the High Knees changes the loading pattern and can reduce the intended work for your Hip Flexors. Keep your hips aligned with the setup cues and move only through the range you can control.
Leaning too far back or forward.
Changing your back position during the High Knees can alter the movement and make the load harder to control. Brace your midsection and keep the torso position called for by the exercise.
Flat-footed landing.
Your foot position during the High Knees determines how force transfers through your body. Keep your feet flat with weight distributed evenly — losing contact with the ground means you're losing power and stability.
Arms not moving with legs.
Squatting patterns like the High Knees coordinate the hips, knees, and feet. Keep those positions consistent and use a range you can control while your Hip Flexors carries the intended load.
All fitness levels. Easily scaled by adjusting speed.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3-4 sets of 30-45 seconds. Rest 15-30 seconds between sets.
