The elbow to knee sit-up is a bodyweight core exercise that combines a sit-up with a rotation, bringing one elbow toward the opposite knee. It primarily targets the obliques, with the rectus abdominis assisting to lift and flex the torso. The twisting action makes it a useful, equipment-free way to build trunk rotation strength and ab definition.

Elbow to Knee Sit-up: So führst du sie aus

  1. 1Lie on your back with your knees bent and feet flat on the floor, hip-width apart.
  2. 2Place your hands lightly behind your head, fingertips at the base of your skull, with your elbows pointing out to the sides.
  3. 3Brace your core and tuck your chin slightly so your neck stays relaxed.
  4. 4Curl your torso up off the floor, rotating as you rise to drive your right elbow toward your left knee.
  5. 5Squeeze your obliques hard at the top, keeping your lower back from arching.
  6. 6Lower under control back to the start without letting your shoulders fully relax on the floor.
  7. 7Repeat to the opposite side, driving your left elbow toward your right knee, and alternate sides for your reps.

Technik-Tipps

  • Lead the movement with your shoulder and ribcage rotating toward the knee, not by yanking on your head with your hands.
  • Keep your elbows wide throughout — pulling them in narrows your focus to your neck and arms instead of your obliques.
  • Exhale as you crunch up and twist, then inhale as you lower to keep your core braced.
  • Move at a deliberate tempo and pause briefly at the top to maximize tension on the obliques.

Häufige Fehler

  • Pulling on your head and neck with your hands, which strains the cervical spine and takes work off the obliques.
  • Using momentum to bounce up rather than curling under control, which cheats the rep and reduces muscle tension.
  • Letting the lower back arch off the floor instead of staying braced, which loads the spine instead of the abs.
  • Rotating only the head and shoulders without flexing the spine, so the rectus abdominis and obliques never fully engage.

Häufig gestellte Fragen

What muscles does the elbow to knee sit-up work?

It primarily targets the obliques, the muscles along the sides of your waist, with the rectus abdominis assisting to flex and lift the torso. The twist is what shifts the emphasis onto the obliques.

Is the elbow to knee sit-up good for beginners?

Yes. It uses only your body weight and needs no equipment, so you can scale it by slowing the tempo or reducing reps. Focus on controlled rotation rather than speed while you learn the movement.

How many sets and reps should I do?

Aim for 2–3 sets of 10–15 reps per side, alternating sides. Increase the reps or add a pause at the top once the movement feels easy and controlled.

Why do I feel this in my neck instead of my abs?

That usually means you are pulling on your head with your hands. Keep your hands light behind your head, lead with your ribcage rotating toward the knee, and let your obliques drive the lift.
