The dumbbell straight leg Russian twist is a rotational core exercise that primarily targets the obliques, with the rectus abdominis, hip flexors (iliopsoas), and quadriceps helping to hold your position. Performed seated with your legs extended and a single dumbbell, it trains anti-rotation control and trunk rotation while challenging your balance.
Dumbbell Straight Leg Russian Twist: So führst du sie aus
- 1Sit on the floor and extend your legs out in front of you, keeping them straight with a slight lift so your heels hover just off the ground.
- 2Lean your torso back to roughly 45 degrees so your body forms a wide V with your legs, and brace your core.
- 3Hold a single dumbbell with both hands close to your chest, elbows slightly bent.
- 4Rotate your torso to one side under control, bringing the dumbbell toward the floor beside your hip.
- 5Pause briefly at the end of the rotation, keeping your legs still and your core engaged.
- 6Rotate back through the center and continue to the opposite side, moving the dumbbell beside the other hip.
- 7Keep alternating sides for the prescribed reps, counting each side as one rep.
- 8Finish by rotating back to center, then bend your knees and set the dumbbell down with control.
Technik-Tipps
- Drive the rotation from your waist and obliques, not your arms — the dumbbell should follow your torso.
- Keep your legs straight and still throughout; the lower body holds position while the trunk does the work.
- Move slowly and with control rather than swinging; a steady tempo keeps tension on the obliques.
- Lower your back angle or bend your knees slightly to make it easier, and lift your heels higher to make it harder.
Häufige Fehler
- Swinging the dumbbell with your arms instead of rotating your torso, which takes the work off the obliques and turns it into a momentum exercise.
- Rounding the lower back as you lean away, which places strain on the spine and weakens your core brace.
- Letting the legs drop, bounce, or bend each rep, which removes tension from the hip flexors and quads and breaks your position.
- Rushing the reps and using momentum, which reduces the time your obliques spend under load and limits the training effect.
- Holding your breath through the set instead of exhaling on the twist, which makes it harder to keep a tight core.
Häufig gestellte Fragen
What muscles does the dumbbell straight leg Russian twist work?
It mainly works the obliques through trunk rotation, while the rectus abdominis and hip flexors (iliopsoas) brace your torso and the quadriceps help hold your straight legs in place.
Is the dumbbell straight leg Russian twist good for beginners?
It can be, but keeping the legs straight and lifted is demanding. Beginners can start with bent knees or heels resting lightly on the floor, then progress to straight, hovering legs as their core gets stronger.
How many sets and reps should I do?
For most lifters, 3 sets of 10 to 16 reps per side works well. Pick a dumbbell weight you can rotate under control without swinging or losing your leg position.
Why should I keep my legs straight instead of bent?
Straight, hovering legs force your hip flexors and quadriceps to hold an extended position, raising the demand on your core and making the rotation harder than the standard bent-knee version.
Where should I feel this exercise?
You should feel it mainly along the sides of your waist (the obliques) as you rotate, with your lower abs and hip flexors working to keep your legs lifted and your torso braced.
