Setup

How each one starts

45° Side Bend — first steps

  1. Stand with your feet shoulder-width apart and your arms extended straight down by your sides.
  2. Keeping your back straight and your core engaged, slowly bend your torso to one side, lowering your hand towards your knee.

Smith Hip Raise — first steps

  1. Position yourself on the smith machine with your back against the pad and your feet shoulder-width apart.
  2. Place your hands on the barbell, slightly wider than shoulder-width apart.

Decision

Which should you choose?

The 45° Side Bend needs no equipment and scales through leverage, tempo and reps. The Smith Hip Raise fixes the bar path so you can push close to failure with less balance demand. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the abs adapting.
