The banded clamshell is a beginner isolation exercise that uses a resistance band to create targeted tension at the hip joint. You perform this movement lying on your side, opening your knees like a clamshell while keeping your feet together.
This hip external rotation movement specifically targets the glutes and hamstrings, putting heavy focus on the gluteus medius and the deep hip rotators. Working these muscles helps build stability in your hips and pelvis for heavier lower body lifts.
How to do it
Loop a small resistance band around both legs just above your knees and lie on your side with your hips and knees bent. Rest your head on your lower arm and stack your hips directly on top of each other.
- Keep your feet touching and brace your core to stabilize your spine.
- Slowly rotate your top knee upward against the resistance band.
- Open your legs as far as you can without letting your top hip roll backward.
- Hold the top position for a brief second to squeeze your gluteus medius.
- Lower your knee back to the starting position under control.
Sets, reps and load
Start with 2 to 3 sets of 12 to 15 repetitions per side. Rest briefly between sides to maintain high quality movement.
Pick a resistance band that allows you to feel a deep burn in your upper glute by the end of the set without forcing your pelvis to twist.
Common mistakes
- Rolling the hips back. Place your top hand on your hip bone to monitor its position. If your hand moves backward, you are opening your knee too far.
- Rushing the reps. Use a slow, controlled tempo to open the knee and close it. This ensures the deep hip rotators do the actual work.
- Lifting the feet. Keep the inside edges of your shoes or feet in constant contact. Only the top knee should move toward the ceiling.
- Using too much tension. Swap to a lighter resistance band if you cannot open your knee a few inches without shifting your torso.
- Dropping the knee. Resist the band pulling your leg down during the lowering phase. Keep tension on the muscles the entire time.
