Band Seated Leg Extension
- Beginner
- Isolation
- Rep-based
- Upper legs
The Band Seated Leg Extension is a unilateral isolation exercise that targets the quadriceps, providing peak resistance at the point of full knee extension. It is excellent for improving knee stability and developing the 'teardrop' muscle (vastus medialis) using portable equipment.

Equipment
Setup
- Sit on the edge of a flat bench with your feet flat on the floor and your back upright.
- Anchor one end of a resistance band to the bench leg behind you and loop the other end around your right ankle.
- Grasp the sides of the bench firmly to stabilize your torso and keep your hips grounded.
- Position your working leg so the back of the knee is resting comfortably against the edge of the bench.
How to do it
- Exhale and extend your right leg forward until the knee is fully straight, moving in a slow, controlled arc.
- Squeeze your quadriceps forcefully at the top of the movement for a one-second pause to maximize muscle fiber recruitment.
- Inhale as you slowly lower your foot back toward the floor, resisting the pull of the band to maintain tension.
- Complete all repetitions on the right leg before switching the band to the left ankle.
Form checklist
- Keep your thigh glued to the bench; do not let it lift as you extend the leg.
- Maintain an upright posture with an engaged core, avoiding the urge to lean back.
- Ensure the band remains under tension even at the bottom of the movement.
- Keep your ankle flexed (toes toward the shin) or neutral to keep the focus on the quadriceps.
Pro tips
- Focus on the 'peak contraction' at the top of the movement where the band's resistance is highest.
- Turn your toes slightly outward during the extension to increase activation of the vastus medialis (inner quad).
Make it harder
- Increase the resistance by scooting the bench further away from the anchor point.
- Incorporate a 3-5 second slow eccentric (lowering) phase to increase time under tension.
