Side Duck Side

  • Intermediate
  • Compound
  • Rep-based
  • Hips
  • Lower legs

The Side Duck Side is a dynamic lateral squat variation that builds lower body endurance and hip stability while engaging the core for balance. It targets the glutes and quadriceps through constant time-under-tension by requiring you to stay low throughout the entire movement.

Equipment

  • Body weight

Setup

  1. Stand with your feet hip-width apart and your hands held at your chest or hips for balance.
  2. Engage your core and pull your shoulder blades back to maintain a neutral spine.
  3. Lower your hips into a half-squat position, ensuring your weight is distributed through your mid-foot and heels.

How to do it

  1. Step your right foot out to the side, maintaining the squat depth and keeping your torso upright.
  2. Bring your left foot toward your right foot until you return to a hip-width stance, staying low without standing up.
  3. Immediately repeat the movement to the left side, stepping out with the left foot and following with the right.
  4. Inhale as you step out and exhale as you bring the trailing foot in, maintaining a steady, rhythmic tempo.

Form checklist

  • Keep your hips at a consistent height; avoid 'bobbing' up and down between steps.
  • Ensure your knees track in line with your toes and do not cave inward.
  • Keep your chest lifted and your gaze forward to prevent the lower back from rounding.
  • Maintain a wide enough step to feel the engagement in your outer glutes and obliques.

Pro tips

  • Imagine you are walking under a very low ceiling to force your legs to stay bent and under constant tension.
  • Focus on pushing off the outer edge of your lead foot to maximize engagement of the gluteus medius and lateral stabilizers.

Make it harder

  • Increase the depth of the squat to a full parallel position to increase the demand on the quadriceps.
  • Place a mini-resistance band just above your knees to add lateral tension and further challenge the glutes.
