The 45 Degree Side Bend is a core exercise that primarily targets the obliques (muscles on the sides of the abdomen). This exercise also engages the rectus abdominis (muscles in the front of the abdomen) and the erector spinae (muscles along the spine) as secondary muscles. The stabilizing muscles involved in this exercise are the muscles surrounding the hips and lower body, including the glutes (muscles in the buttocks) and the quadratus lumborum (deep muscles in the lower back), which help maintain proper posture and balance during the movement.
