45 Degrees Side Bend
45 Degrees Side Bend Exercise Description
The 45° Side Bend is a standing lateral flexion drill using only body weight. It primarily targets the internal and external obliques, with assistance from the quadratus lumborum and spinal stabilizers (transverse abdominis and erector spinae). The goal is controlled rib-to-pelvis approximation on one side while the pelvis stays level and the torso avoids twisting. You’ll move in the frontal plane only—think “ear to hip” without bending forward or leaning back. Work through a comfortable range that you can control; the exact angle is less important than maintaining alignment, steady breathing, and tension through the trunk. Expect a mild stretch on the long side and a strong contraction on the working side when done correctly.

How To Do The 45 Degrees Side Bend Exercise
‘- Stand tall with feet hip-width, knees soft, and weight evenly distributed. Arms rest at your sides.
– Set posture: ribs down, pelvis neutral, long spine, chin tucked slightly. Gently brace your abdomen (as if preparing for a cough).
– Inhale. Without rotating, slide your right hand down the outside of your right thigh as your torso laterally flexes to the right.
– Keep shoulders level, hips square, and both feet planted. Avoid hiking the hip or letting the chest turn.
– Stop at a controlled end range where alignment is maintained and you feel a stretch on the left side.
– Exhale and draw the left ribs toward the left pelvis to return to tall standing.
– Repeat to the opposite side: left hand slides down the left thigh while the torso bends left.
– Throughout, keep the neck neutral, eyes forward, and movement smooth—no bouncing or jerking.
45 Degrees Side Bend Tips
‘- Stand tall with feet hip-width, knees soft, and weight evenly distributed before you start bending.
– Set ribs down, pelvis neutral, long spine, and a slight chin tuck to establish your posture.
– Gently brace your abdomen as if preparing for a cough before initiating each side bend.
– As you bend, slide your hand straight down the outside of the same-side thigh to guide a pure lateral motion.
– Keep shoulders level and hips square, avoiding any chest rotation or hip hiking.
– Stop the bend where you can maintain alignment and feel a stretch on the long side.
– On the way back up, exhale and actively draw the ribs toward the pelvis on the returning side.
– Keep your neck neutral with eyes forward throughout the movement.
– Move smoothly in and out of the bend, avoiding any bouncing or jerking.
45 Degrees Side Bend Beginner Introduction
The 45° Side Bend is a standing, bodyweight core move that trains side-to-side control rather than forward crunching. Performed upright with a relaxed, balanced stance, it concentrates on the side abs while also engaging the deep core and muscles along the lower back. Because there is no added load, attention centers on precision, posture, and gentle tension through the trunk instead of sheer strength or heavy resistance.
During this movement, the upper body glides toward one side and then returns to the middle, creating a shortening feeling on the working side and a light lengthening sensation on the opposite side. The hips remain level, the chest faces forward, and the bend happens like a smooth arc, not a twist or a lean backward or forward. Breathing stays calm and steady so the ribs and pelvis can draw slightly closer on one side without gripping or strain. When practiced with control, this drill highlights how the core supports side bending while keeping the spine organized and stable.
