Exercise guide

Smith Lateral Step-Up

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

This unilateral compound movement targets the glutes and quads while the Smith machine provides stability, allowing for greater focus on lateral drive and hip abduction. It is highly effective for correcting muscle imbalances and building lower body power through a controlled range of motion.

Equipment

  • Smith machine

Setup

  1. Position a flat bench or sturdy step platform inside the Smith machine, parallel to the bar path.
  2. Set the bar at shoulder height and stand sideways to the platform, placing the foot of the leg closest to the bench firmly on its center.
  3. Position the bar across your upper traps, unhook it, and establish a balanced stance with the trailing foot on the floor.

How to do it

  1. Drive through the heel of the elevated foot to lift your body vertically, exhaling as you fully straighten the working leg.
  2. At the top of the movement, squeeze your glutes briefly while maintaining a slight bend in the knee to keep tension on the muscle.
  3. Lower your body under control for a 3-second count until the trailing foot lightly touches the floor, inhaling during the descent.

Form checklist

  • Keep the working knee tracking directly over the middle of the foot to prevent internal collapse.
  • Ensure the trailing leg does not 'cheat' by pushing off the floor to initiate the movement.
  • Maintain a proud chest and neutral spine, avoiding excessive rounding or arching.
  • Keep your hips level throughout the movement to ensure the glute medius is properly engaged.

Pro tips

  • Hinge slightly forward at the hips while keeping your back flat to increase the stretch and recruitment of the gluteus maximus.
  • Focus on a 'soft touch' with the trailing foot to ensure the working leg is responsible for 100% of the weight displacement.

Make it harder

  • Increase the height of the step to deepen the hip flexion and increase the range of motion.
  • Add a 2-second pause at the bottom of each repetition to eliminate momentum and increase time under tension.
