Band Side Clam

A glute medius activation exercise using a resistance band, performed lying on the side and opening the knees against tension. It wakes up the hip stabilizers that keep knees tracking well in squats and lunges, which is why it leads so many lower body warm-ups. The movement is small and the band light by design; feeling the outer glute work is the entire goal.

How to Do the Band Side Clam

  1. Loop a band just above your knees and lie on your side with knees bent and stacked.
  2. Rest your head on your lower arm and stack your hips vertically.
  3. Keeping your feet together, lift the top knee open against the band.
  4. Open as far as you can without the top hip rolling backward.
  5. Squeeze the outer glute for a beat at the top.
  6. Close slowly and complete the set before rolling to the other side.

Do This

Form Cues

  • Stack your hips so the top hip sits directly over the bottom one.
  • Keep the feet together and open only at the knee.
  • Move slowly. This is an activation drill, not a strength lift.
  • Keep the top hip stacked directly over the bottom one. The moment it rolls back, the range is fake.

Avoid This

Common Mistakes

  • Rolling the top hip backward to open the knee further.
  • Using a band so heavy that the hip has to rotate to move at all.
  • Rushing reps so the glute never actually contracts.
  • Counting fast, floppy reps. Ten slow reps with a squeeze beat thirty rushed ones.
