The bent-knee side plank is a bodyweight isometric hold that targets the obliques along the side of your waist. By bending the knees to shorten the lever, it is an easier regression of the full side plank, making it a solid starting point for building lateral core stability and anti-side-bend strength.
Bent-Knee Side Plank: So führst du sie aus
- 1Lie on your side on a mat with your knees bent to roughly 90 degrees and stacked on top of each other.
- 2Place your bottom forearm flat on the floor with the elbow directly under your shoulder, forearm pointing forward.
- 3Brace your core and squeeze your glutes, then lift your hips off the floor so your weight rests on your forearm and the side of your bottom knee.
- 4Form a straight line from your shoulders through your hips to your knees, keeping your neck long and your head in line with your spine.
- 5Hold this position while breathing steadily, keeping your hips lifted and level for the target time (for example, 20 to 40 seconds).
- 6Avoid letting your hips sag or rotate forward or back throughout the hold.
- 7Lower your hips to the floor under control to finish the hold.
- 8Switch to the other side and repeat for the same hold time to train both obliques evenly.
Technik-Tipps
- Drive your bottom elbow into the floor and push your shoulder away from your ear to keep the working shoulder stable.
- Keep your abs braced and glutes squeezed the entire hold so the line from shoulder to knee stays rigid.
- Breathe slowly and continuously rather than holding your breath, so you can maintain tension for the full duration.
- Start with shorter holds and add time gradually; quality of the straight line matters more than chasing a long time.
- Stack your top hand on your hip or reach it toward the ceiling, but avoid pushing into the floor with it to make the hold easier.
Häufige Fehler
- Letting the hips sag toward the floor, which removes tension from the obliques and shifts strain onto the lower back.
- Rotating the hips or shoulders forward, which turns the hold into a partial front plank and takes the obliques out of the work.
- Placing the elbow too far forward or out to the side instead of directly under the shoulder, which stresses the shoulder joint.
- Holding your breath to brace, which spikes tension and forces you to cut the hold short.
- Training only your stronger side, which lets a muscle imbalance develop across the waist.
Häufig gestellte Fragen
What muscles does the bent-knee side plank work?
It primarily works the obliques along the side of your waist, which resist gravity to keep your hips lifted and your torso from bending sideways during the hold.
How long should I hold a bent-knee side plank?
Aim for 20 to 40 seconds per side, repeated for 2 to 3 sets. Once you can hold a clean, level position for the full time, progress toward the straight-leg side plank.
Is the bent-knee side plank good for beginners?
Yes. Bending the knees shortens the lever and reduces the load, making it one of the easiest side plank variations and a good entry point for building lateral core strength.
What is a good progression from the bent-knee side plank?
Once the bent-knee version feels easy, progress to the full straight-leg side plank, which extends the lever and increases the demand on your obliques.
