The Standing Side Bend (bent arm) is a body weight waist exercise that targets the obliques while engaging the iliopsoas as a synergist to stabilize the pelvis. You perform a controlled lateral trunk flexion from a standing position with one arm bent overhead, loading the side of the torso through a full range of motion. It is well suited for building lateral core strength and improving waist flexibility.
Standing Side Bend (bent arm): So führst du sie aus
- 1Stand with your feet hip-width apart, spine tall, and shoulders relaxed.
- 2Raise one arm and bend it so your hand rests behind your head with your elbow pointing toward the ceiling; let the other arm hang relaxed at your side or rest on your hip.
- 3Brace your core lightly and set your hips square and level — they should not shift or tilt throughout the movement.
- 4Exhale and bend your torso directly to the side opposite the bent arm, allowing the obliques to lengthen as your elbow arcs downward.
- 5Descend only as far as you can control with the spine staying in the same plane — no forward lean or rotation.
- 6Pause briefly at the end of the bend, feeling the stretch along the obliques on the far side of your torso.
- 7Inhale and contract the obliques on the bending side to pull your torso back to the upright starting position.
- 8Complete all reps on one side, then switch arms and repeat on the other side.
Technik-Tipps
- Imagine sliding your torso between two panes of glass — keep the movement strictly in the frontal plane with no forward or backward rotation.
- The bent arm increases the effective moment arm compared to a hand on the hip; use this to deepen the oblique stretch rather than to rush through extra range.
- Slow the descent to a 2-second count and the return to a 2-second count; removing momentum keeps continuous tension on the obliques throughout each rep.
- Exhale on the way down and inhale on the return; controlled breathing maintains intra-abdominal pressure and protects the lumbar spine.
- If you feel pinching on the bending side rather than a stretch on the far side, shorten your range of motion and focus on rib-cage separation before adding depth.
Häufige Fehler
- Rotating the torso during the bend: turning the shoulders forward or backward shifts the load away from the obliques onto the spinal rotators, reducing effectiveness and placing uneven stress on the lumbar discs.
- Hiking or pushing the hip outward: shifting the hip to the side to gain extra range makes the movement hip-driven rather than spine-driven, bypassing the obliques and eliminating the intended stimulus.
- Using momentum to swing through the rep: bouncing at the bottom or swinging back up removes time under tension from the obliques and can push the torso past a safe lateral range.
- Rounding or collapsing the upper back: hunching forward makes true lateral flexion impossible, compresses the anterior spine unevenly, and shifts load to the wrong structures.
- Skipping the return contraction: lowering into the bend is only half the rep; passively falling back to upright eliminates the concentric oblique work and reduces overall training effect.
Häufig gestellte Fragen
What muscles does the Standing Side Bend (bent arm) work?
The Standing Side Bend (bent arm) primarily targets the obliques, which control lateral flexion of the torso. The iliopsoas acts as a synergist, stabilizing the pelvis and hip throughout the movement. Surrounding core and spinal muscles also contribute to maintaining posture during the exercise.
Is the Standing Side Bend (bent arm) good for beginners?
Yes, it is accessible to beginners because it requires no equipment and the range of motion can be adjusted to your current flexibility. Start with a small, controlled bend, focus on keeping your hips square, and gradually increase depth as your oblique strength and lateral flexibility improve.
How many sets and reps should I do for the Standing Side Bend (bent arm)?
Two to three sets of 12–20 reps per side is a practical starting point for building oblique endurance. Use a slow, deliberate tempo — about 2 seconds down and 2 seconds back up — to maximize time under tension and avoid relying on momentum.
Where should I feel the Standing Side Bend (bent arm)?
You should feel a stretch along the obliques on the side opposite the bend and a mild contraction on the bending side as you return to upright. If you feel discomfort in the lower back rather than a lateral stretch, check that your hips are not shifting and that you are not rotating your torso.
What is the difference between the Standing Side Bend with a bent arm and a straight arm?
The bent-arm position reduces the lever length compared to a fully extended arm, placing less strain on the shoulder joint while still providing a full oblique stretch. A straight-arm variation creates a longer moment arm, increasing the pull on the obliques and the demand on the overhead shoulder — use the bent-arm version if shoulder mobility is a limiting factor.
