Equipment

  • Smith machine

Setup

  1. Place a gym mat on the floor directly underneath the Smith machine bar.
  2. Lie on your back with your hips positioned directly under the bar and your arms flat at your sides for stability.
  3. Extend your legs vertically and place the arches of your feet firmly against the center of the bar.
  4. Carefully unlock the bar from the hooks, supporting the weight entirely with your legs.

How to do it

  1. Exhale and contract your abdominals to lift your sacrum and lower back off the floor, driving the bar straight upward.
  2. Focus on curling your pelvis toward your ribcage rather than simply pushing with your legs.
  3. Inhale as you slowly lower your hips back to the floor using a controlled 3-second tempo.
  4. Touch the floor lightly with your glutes and immediately begin the next repetition to maintain constant tension.

Form checklist

  • Keep your legs as straight as possible to maximize the lever length.
  • Ensure the bar travels in a perfectly vertical path without tilting.
  • Avoid using your arms to press into the floor for momentum.
  • Keep your head and upper back relaxed on the mat throughout the set.

Pro tips

  • Think about 'peeling' your spine off the floor one vertebra at a time to maximize muscle fiber recruitment in the lower abs.
  • Pause for one second at the top of the movement to emphasize the peak contraction of the obliques and rectus abdominis.

Make it harder

  • Add small weight plates to the bar to increase the resistance against hip flexion.
  • Perform the eccentric (lowering) phase even slower, taking 5 seconds to return to the starting position.
