Foundation exercise for knee rehab.

Keep knee locked straight.

Control the lowering phase.

What are common Straight Leg Raise mistakes to avoid?

Bending knee during lift.

Letting your knees collapse inward during the Straight Leg Raise puts dangerous rotational force on your knee ligaments. Push your knees out over your toes throughout the movement.

Lifting too high which shifts load to hip flexors.

Losing hip position during the Straight Leg Raise shifts the loading pattern away from your Quadriceps and can compress your lower back. Stay planted and let your Quadriceps do the work.

Not contracting quad first.

During any pressing movement like the Straight Leg Raise, this mistake reduces how effectively your Quadriceps can produce force. Focus on the muscle you're trying to work — if you can't feel your Quadriceps driving the movement, something is off.

How to Program the Straight Leg Raise

Strength10-12 reps

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.

Muscle Growth12-15 reps

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.

Endurance15-20 reps

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 sets of 12-15 each leg. Rest 30 seconds.
