Side Plank Clamshell
The Side Plank Clamshell is a hybrid movement that combines a modified side plank with a clamshell leg motion to strengthen the glutes, obliques, and hip stabilizers. This unique combo targets the lateral core and outer hips, which are essential for balance, posture, and injury prevention.
This variation is particularly useful for runners, lifters, and individuals recovering from hip or knee pain. By integrating hip abduction with trunk stability, the Side Plank Clamshell promotes better alignment and muscular coordination. It’s commonly used in warm-ups, glute activation series, or as a low-load strength drill.
This movement is low-impact, requires minimal equipment, and can be scaled for beginners or progressed for more advanced users. It’s a go-to option for anyone looking to enhance lateral core stability and glute function.
The Side Plank Clamshell is an efficient way to combine glute strengthening and core training in one movement. Use it to reinforce pelvic stability, build strength in hard-to-reach muscles, and support injury prevention through better movement control.
Equipment Needed:
- Resistance band (optional)
- Yoga mat or soft surface
How to Perform the Side Plank Clamshell:
- Lie on your side with your knees bent at 90 degrees and your forearm underneath your shoulder.
- Press your bottom knee and forearm into the ground to lift your hips off the floor into a modified side plank position.
- With feet touching, lift your top knee while maintaining alignment through the hips and spine.
- Pause briefly at the top, then lower the knee with control.
- Repeat for reps and switch sides.
Common Side Plank Clamshell Mistakes:
- Allowing hips to sag or rotate backward
- Failing to maintain core engagement
- Relying on momentum rather than controlled motion
- Arching the lower back during the lift
Progressions and Regressions:
If this exercise is too challenging:
- Perform just the clamshell without lifting into a plank
- Reduce range of motion or skip resistance band
- Hold the modified side plank position without movement
If you want more of a challenge:
- Use a resistance band above your knees
- Extend legs to perform in a full side plank
- Add a pause at the top or increase total reps per set
