Side Bridge Hip Abduction Star

Body Part: Hips

Muscle: Obliques

Equipment: Body Weight

Side Bridge Hip Abduction (star) is a bodyweight side-plank variation that trains lateral core strength, hip stability, and glute control at the same time. From the full side-bridge position, you lift and hold the top leg away from the bottom leg, creating the star shape shown in the image. That extra lever makes the obliques work harder to keep the trunk from sagging or twisting while the outer hip of the top leg resists collapse.

The exercise is especially useful when you want the torso and pelvis to stay aligned under one-sided load. The working side has to support bodyweight through the forearm and the side of the foot while the top hip stays open and the lifted leg stays active. In anatomy terms, the main work centers on the External obliques, with assistance from the Rectus abdominis, Erector spinae, and Transversus abdominis for anti-rotation and spinal control.

Because the position is long and unsupported, the setup matters more than speed. Place the forearm directly under the shoulder, press the elbow and outer forearm into the floor, stack the feet or place the top foot slightly forward for balance, and lift the hips until the body forms one straight line from head to heel. Once you are stable, raise the top leg without letting the pelvis roll backward or the waist collapse toward the floor.

Each repetition should feel like a controlled reach, not a kick. Keep the lower rib cage tucked, the neck long, and the torso rigid while the lifted leg opens away from the body. Hold the top position briefly, then lower the leg with control before resetting the hip height if needed. Breathe steadily so the trunk stays braced without locking up.

Use Side Bridge Hip Abduction (star) as an accessory core drill, a glute-medius builder, or a progression from a standard side plank when you need more pelvic control. It fits well in warmups, athletic prep, and core-focused strength blocks. If you lose the straight line through the body, start with the plain side bridge first and add the leg lift only when you can keep the trunk quiet throughout the set.

Instructions

• Lie on one side and place the lower forearm on the floor so the elbow is directly under the shoulder, then stack the feet or set the top foot slightly in front for balance.
• Press through the forearm and the outer edge of the bottom foot to lift the hips until your body forms a straight line from head to heel.
• Set the free arm straight up toward the ceiling and keep the ribs pulled down so the torso does not rotate open or sink.
• Once the side bridge is stable, lift the top leg away from the bottom leg without letting the pelvis tip backward.
• Raise the leg only as high as you can keep the waist long, the hip stacked, and the trunk still.
• Pause briefly at the top of the abduction while keeping pressure through the supporting forearm and foot.
• Lower the lifted leg under control until the feet are back together or nearly together, then keep the hips elevated.
• Repeat for the planned reps, then lower the hips to the floor with control and switch sides.

Tips & Tricks

• If your shoulder feels pinched, move the elbow a little farther under the shoulder so the joint is stacked before you lift.
• Think about pushing the floor away with the forearm; that cue helps the ribs stay lifted and keeps the bottom shoulder from collapsing.
• A small top-leg lift with a quiet torso is better than a high swing that twists the pelvis open.
• Keep the lifted foot flexed if you want more hip control and less toe-pointing momentum.
• Do not let the top hip drift behind the bottom hip; stay stacked so the obliques and outer glute do the work.
• If the waist sags, shorten the set or regress to a plain side plank before adding the leg lift.
• Use a slow lower on the top leg so the glute on the lifted side keeps tension throughout the rep.
• Exhale as the leg lifts and keep the breath smooth instead of holding it until the neck and traps tighten.

Frequently Asked Questions

What muscle does Side Bridge Hip Abduction (star) target most?

The obliques are the main target, with the outer hip of the lifted leg and the shoulder on the floor working hard to stabilize the position.

Can beginners perform this exercise?

Yes, but many beginners should master a regular side plank first. Add the leg lift only when you can hold the side bridge without the hips dropping.

Where should my elbow and shoulder be in the side bridge?

Set the elbow directly under the shoulder so the forearm is vertical and the joint stack can support your bodyweight without sliding forward.

How high should I lift the top leg?

Lift it only as high as you can keep the pelvis stacked. A smaller lift with a stable trunk is more effective than a big swing.

What is the main mistake with the star position?

The most common error is letting the top hip roll open or the waist sink toward the floor while the leg rises.

Should my free arm do anything during the rep?

Reach it straight up to help you stay stacked, but do not use it to twist the chest or swing for balance.

How can I make this easier?

Keep both feet stacked and remove the leg lift, or bend the bottom knee to the floor for more support while you build side-plank strength.

How do I breathe during the hold?

Exhale as you lift the leg, then take small controlled breaths while keeping the ribs down and the trunk braced.
