Side Plank
The Side Plank is an effective core stabilization exercise that strengthens the muscles responsible for resisting side bending and maintaining proper spinal alignment.
In addition to strengthening the obliques, the Side Plank recruits the shoulders, hips and glutes to create a strong, stable body position. It is an excellent exercise for improving postural stability, athletic performance and functional strength used during everyday activities.
How to Perform
Lie on your side with your legs fully extended and stacked one on top of the other. Position your elbow directly beneath your shoulder with your forearm resting comfortably on the floor.
Press your forearm firmly into the ground and lift your hips until your body forms a straight line from your head through your shoulders, hips, knees and ankles. Keep your top hand resting on your hip as demonstrated.
Brace your abdominal muscles while gently tightening your glutes. Maintain a neutral head position by looking straight ahead and avoid allowing your shoulders or hips to rotate forward or backward.
Hold the position while breathing normally. Maintain full-body tension throughout the exercise before lowering yourself slowly and repeating on the opposite side.
Tips
Imagine your body is sandwiched between two panes of glass. This visual cue helps prevent your shoulders and hips from rolling forward or backward.
Keep your supporting shoulder pressed away from your ear throughout the hold. This creates better shoulder stability and reduces unnecessary tension in the neck.
Lift your hips as high as needed to maintain a perfectly straight line from head to feet. If your hips begin to sag, end the repetition rather than sacrificing proper form.
Continue breathing naturally throughout the hold. Slow, controlled breathing helps maintain core engagement without creating unnecessary fatigue.
Benefits
The Side Plank strengthens the muscles responsible for lateral trunk stability, helping improve balance and overall core endurance.
Developing stronger oblique muscles enhances spinal stability during lifting, walking, running and many rotational movements used in sports and daily life.
The exercise also improves shoulder stability by requiring the supporting arm and shoulder muscles to maintain a strong, controlled position throughout the hold.
Because the movement relies on isometric muscle contractions rather than repeated spinal motion, it provides an effective method of building core strength while reinforcing proper posture and body alignment.
Common Mistakes
Allowing the hips to drop reduces activation of the core muscles while placing additional stress on the lower back and supporting shoulder.
Positioning the supporting elbow too far away from the shoulder increases stress on the shoulder joint and reduces overall stability.
Rolling the chest toward the floor or backward changes the exercise mechanics and decreases activation of the lateral core muscles.
Holding your breath throughout the exercise often leads to unnecessary muscle tension and makes it more difficult to maintain proper technique.
FAQ
Safety Note
Keep your elbow positioned directly beneath your shoulder to minimize stress on the shoulder joint.
Maintain a straight body position throughout the exercise rather than allowing your spine to bend or twist.
Discontinue the exercise if you experience pain in your shoulder, elbow or lower back rather than normal muscular fatigue.
Focus on maintaining excellent form instead of increasing hold time. Proper technique is more important than duration.
