Common High Knees mistakes
Knees not reaching hip height.
Losing hip position during the High Knees shifts the loading pattern away from your Hip Flexors and can compress your lower back. Stay planted and let your Hip Flexors do the work.
Leaning too far back or forward.
A compromised back position during the High Knees puts your spine under unnecessary shear force. Brace your core and maintain a neutral spine throughout the movement.
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 load your entire lower body. This mistake shifts that load to structures that weren't designed to handle it. Stay controlled and let your Hip Flexors absorb the work.

How to Program the High Knees
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.
