Resistance Band Seated Single Leg Hugging Knee Fl
- Beginner
- Compound
- Rep-based
- Lower legs
- Upper legs
This exercise isolates the quadriceps, specifically targeting the rectus femoris by using a 'knee hug' to stabilize the pelvis and prevent lower back compensation. It is an effective unilateral movement for correcting muscle imbalances and improving knee terminal extension.

Setup
- Sit on the edge of a flat bench and loop a resistance band around your right ankle, anchoring the other end firmly behind the bench or under a bench leg.
- Lift your left knee toward your chest and wrap both arms around it, 'hugging' it tightly to tilt your pelvis back and stabilize your spine.
- Position your right thigh so it is parallel to the floor with your foot hovering just above the ground.
How to do it
- Exhale as you slowly extend your right leg forward until the knee is fully locked out, focusing on a hard contraction in the quadriceps.
- Hold the peak contraction for one second at the top of the movement to maximize muscle fiber recruitment.
- Inhale as you slowly lower your foot back to the starting position, maintaining tension on the band throughout the descent.
- Complete the desired number of repetitions for the right leg before switching the band and the 'hug' to the opposite side.
Form checklist
- Keep the non-working knee hugged tightly to your chest to prevent the lower back from arching.
- Ensure the movement occurs only at the knee joint; keep the working thigh stationary on the bench.
- Control the tempo—avoid 'kicking' the leg up or letting the band snap the leg back down.
- Keep your torso upright and avoid leaning backward as you extend the leg.
Pro tips
- For maximum rectus femoris engagement, focus on squeezing the quad so hard at the top that you feel a slight 'cramp' sensation.
- Point your toes slightly outward (external rotation) to place more emphasis on the vastus medialis (teardrop muscle).
Make it harder
- Increase the time under tension by using a 3-second eccentric (lowering) phase.
- Use a heavier resistance band or move further away from the anchor point to increase the starting tension.
