Seated Alternate Knee Extension on Chair
Seated on a chair with no load, straighten one knee and then the other, lowering each foot back to the floor.
How to do it
Setup
Seated tall on a chair, hands on the thighs, feet flat and hip-width.
Steps
- Straighten one knee until the leg is level.
- Tighten the thigh at the top for a beat.
- Lower the foot and straighten the other knee.
Common mistakes
Kicking the leg up: lift it smoothly and lower it the same way. Leaning back as the leg rises: sit tall. Stopping short of straight: finish the extension every rep.
Breathing
Exhale extending, inhale lowering.
