Side Bridge With Straight Legs
Side Bridge With Straight Legs Exercise Description
The Side Bridge with Straight Legs (side plank) is an anti‑lateral‑flexion core exercise that builds trunk stability while maintaining a neutral spine. It primarily targets the external and internal obliques and quadratus lumborum, with important stabilizing roles from the gluteus medius/minimus, transverse abdominis, and shoulder girdle (serratus anterior, rotator cuff). Performed correctly, it teaches whole‑body tension, pelvic control, and shoulder stacking without spinal movement. Keeping the legs long increases the lever arm, challenging the lateral core and hip stabilizers to keep the body in one straight line. The focus is quality positioning and steady breathing while resisting sagging, piking, or rotation.

How To Do The Side Bridge With Straight Legs Exercise
‘- Lie on your side with legs straight, feet stacked, and knees fully extended.
– Place your bottom forearm on the floor with the elbow directly under the shoulder; forearm perpendicular to your body, hand relaxed.
– Stack hips and shoulders vertically; align head with spine and gaze forward.
– Lightly brace your trunk (360° abdominal tension) and squeeze your glutes.
– Press the forearm and the outside edge of the bottom foot into the floor to lift the hips.
– Form a straight line from ears through shoulders, hips, knees, and ankles—no sagging or piking.
– Keep ribs down, pelvis level, and avoid rolling forward or backward.
– Push the floor away to keep the bottom shoulder stable; avoid shrugging toward the ear.
– Breathe steadily through the nose or pursed lips while maintaining the brace.
– Maintain the position with control, then lower the hips softly to the floor.
– Switch sides, resetting alignment before repeating.

Side Bridge With Straight Legs Beginner Introduction
The Side Bridge with Straight Legs (side plank) is a static core position where the body is supported on one forearm and the side of one foot, forming a long, straight line from head to heels. Rather than bending or crunching, the exercise challenges the body to resist side‑bending and twisting, so the middle of the body stays steady. This places strong demand on the side abs and side of the lower back, with important support from the glutes, deep abs, and the shoulder muscles that steady the upper body.
Because the legs remain long, the load is spread along the entire length of the body, increasing the challenge to the core and hip area. The shoulder on the supporting side also plays a significant role, as it works to hold the upper body lifted and stable. Attention to body alignment, a calm, even breath, and a controlled hold turns this into a full‑body tension exercise that teaches how to keep the pelvis, ribs, and shoulders organized in one unified position from start to finish.
