How to do Knee - Extension
- 01Setup
Sit tall on the edge of a sturdy chair or bench, ensuring your feet are flat on the floor and your knees are bent at approximately a 90-degree angle.
- 02Setup
Keep your back straight and core lightly engaged, resting your hands on your thighs or by your sides for stability.
- 03
Slowly extend one leg straight out in front of you by contracting your quadriceps, keeping your thigh firmly on the chair and your back upright.
- 04
Briefly hold the fully extended position, squeezing your quad muscle at the top, ensuring your knee is not hyperextended or locked out.
- 05
With control, slowly lower your foot back to the starting position, allowing your knee to bend back to 90 degrees.
- 06
Complete all repetitions on one leg before switching to the other, maintaining a smooth and controlled tempo throughout the exercise.
Tips
- Focus on a strong, deliberate contraction of your quadriceps at the top of the movement to maximize muscle engagement.
- Maintain a slow and controlled tempo during both the extension and lowering phases, resisting the urge to use momentum.
- Keep your hips stable and anchored to the seat, preventing any rocking or leaning back to isolate the quad muscles effectively.
- Breathe out as you extend your leg and inhale as you slowly return to the starting position, coordinating your breath with the movement.
Common mistakes
- Using momentum to swing the leg up reduces quadriceps engagement; instead, perform the movement with controlled muscle activation.
- Hyperextending or locking out the knee at the top can strain the joint; stop just before full lockout to protect your knee.
- Leaning back or arching the lower back indicates a loss of core stability; keep your torso upright and core engaged to prevent this.
