# Side Bridge With Straight Legs - Canonical: https://fitwill.app/exercise/4458/side-bridge-with-straight-legs/ - Media ID: 4458 - Primary muscle: Obliques - Body part: Waist - Equipment: Body Weight ## Description Side Bridge With Straight Legs is a bodyweight side plank variation that trains the obliques to resist side-bending while the hips stay lifted and the whole body stays in one long line. The image shows a forearm support on the bottom arm, straight legs, and the feet stacked so the torso has to hold a rigid side-on position instead of rotating forward or back. That makes the exercise especially useful for building lateral core endurance, hip stability, and shoulder support in a simple, no-equipment setup. The main demand is anti-lateral flexion: your waist and trunk have to stop the pelvis from sagging toward the floor. The external obliques do most of that work, while the rectus abdominis, transversus abdominis, glute medius, and the shoulder on the floor side help keep the body aligned. Because the position is long-lever and unforgiving, small setup errors show up quickly. If the elbow is too far from the shoulder, the ribs flare, or the top hip rolls forward, the set becomes harder in the wrong places and the target muscles lose tension. A good rep starts with the forearm planted directly under the shoulder, the legs straight, and the outer edge of the bottom foot or stacked feet taking the lower-body support. From there, lift the hips until the head, rib cage, pelvis, and ankles form a straight diagonal line. Keep the top shoulder stacked over the bottom shoulder, squeeze the side of the waist, and avoid shrugging into the neck. Breathing should stay controlled and quiet so the trunk stays braced instead of twisting through the midsection. This exercise fits well in core circuits, warmups, or accessory work when you want anti-rotation and anti-side-bend control without loading the spine externally. It is also a useful regression or progression point depending on how long you hold the position, whether the knees stay bent or straight, and whether you use a floor, bench, or elevated support. Beginners can do it if they can maintain the line from shoulder to ankle; otherwise, shortening the lever or bending the knees is usually a better starting point. Safety matters most at the shoulder and lower back. If the shoulder feels jammed, re-stack the elbow and press the forearm more firmly into the floor. If the low back takes over, lower the hips slightly, reset the ribs, and shorten the hold before fatigue turns the position into a twist. The goal is a steady, controlled side plank that looks almost still from rep to rep, with the obliques and hip stabilizers doing the work and the spine staying long and neutral. ## Instructions 1. Lie on your side with your bottom forearm on the floor, elbow directly under your shoulder, and your legs straight with the feet stacked or lightly staggered. 2. Press the forearm into the floor and set the shoulder blade down and back so the neck stays long. 3. Brace your midsection before you lift, keeping the ribs from flaring and the pelvis from tipping forward. 4. Drive through the forearm and the outer edge of the bottom foot to lift your hips off the floor. 5. Raise the hips until your body makes a straight line from head to ankles. 6. Keep the top shoulder stacked over the bottom shoulder and the hips stacked over the base foot. 7. Hold the position while breathing steadily and keeping the waist tight. 8. Lower the hips with control if the set is rep-based, or keep holding until the planned time ends. ## Tips & Tricks - Keep the elbow pinned under the shoulder; if it drifts forward, the shoulder takes unnecessary strain. - Stack the feet cleanly when possible, but stagger them slightly if you need a steadier base. - Lift the hips high enough that the bottom waist does not collapse toward the floor. - Squeeze the outer hip and obliques on the floor side to keep the pelvis level. - Do not let the top shoulder roll open toward the ceiling; keep the chest facing the wall in front of you. - Keep the neck neutral by looking straight ahead or slightly down instead of craning upward. - Use shorter holds before the low back starts to arch or the body starts shaking out of position. - If your forearm slips, reset the shoulder and hand position before continuing rather than forcing the hold. ## Frequently Asked Questions ### What muscle does Side Bridge With Straight Legs target most? The obliques are the main target, especially the external obliques on the side closest to the floor. ### Can beginners perform this exercise? Yes. Beginners often start with shorter holds or a bent-knee side plank before moving to the straight-leg version. ### Where should my elbow be during the setup? Place the elbow directly under the shoulder so the forearm can support you without crowding the joint. ### Why do my hips drop during the hold? That usually means the obliques and side glutes are fatiguing or the hold is too long. Lower the time or shorten the lever until you can keep the line straight. ### Should I feel this in my shoulders too? A little shoulder work is normal because the bottom arm supports you, but the set should still feel centered in the waist and side hip. ### Can I do this on a bench instead of the floor? Yes. An elevated support can make the exercise easier by reducing the lever length and helping you keep the torso stacked. ### What is the biggest form mistake to avoid? Letting the hips sag or the chest roll open. Both shift tension away from the obliques and reduce the value of the hold. ### How do I progress the movement over time? Increase hold time, straighten the legs more firmly, or move to a less stable setup such as stacked feet instead of a wider stance.
