The twisting crunch is a bodyweight core exercise that targets the obliques by adding rotation to a standard crunch, with the rectus abdominis working as a synergist throughout each rep. Performed lying on your back, you curl up and rotate one shoulder toward the opposite knee on each rep, alternating sides. It is an effective, equipment-free movement for building rotational core strength and waist definition.

Twisting Crunch: So führst du sie aus

  1. 1Lie flat on your back on a mat with your knees bent at roughly 90° and your feet flat on the floor, hip-width apart.
  2. 2Place your hands lightly behind your head with your elbows wide and your fingertips touching — do not interlace your fingers.
  3. 3Brace your core by drawing your navel gently toward your spine, and keep that tension throughout the set.
  4. 4Exhale and curl your upper back off the mat, simultaneously rotating your right shoulder toward your left knee.
  5. 5Pause briefly at the top of the movement, feeling the contraction in your left oblique and through your rectus abdominis.
  6. 6Inhale as you lower your upper back with control until your shoulder blades lightly touch the mat — do not fully relax your core.
  7. 7On the next rep, exhale, curl up, and rotate your left shoulder toward your right knee, working the right oblique.
  8. 8Continue alternating sides for the desired number of repetitions, keeping each rep deliberate and controlled.

Technik-Tipps

  • Maintain a fist-width of space between your chin and chest — imagine holding a small object under your chin to avoid straining your neck.
  • Drive the rotation from your shoulder and ribcage, not your elbow. Your torso should twist, bringing the shoulder blade toward the opposite knee.
  • Use a slow, controlled tempo — about 2 seconds up and 2 seconds down — to keep constant tension on the obliques and rectus abdominis instead of using momentum.
  • Keep your feet flat on the floor throughout; if they lift, slow the movement or reduce your range of motion until your core strength improves.

Häufige Fehler

  • Pulling your head forward with your hands — yanking on your neck strains the cervical spine and shifts the work away from your core muscles entirely.
  • Rotating only at the elbow instead of the torso — the obliques are only engaged when your shoulder and ribcage twist toward the opposite knee; moving just the elbow misses the target muscle.
  • Using momentum to rock up and down instead of controlling each rep — momentum reduces time under tension in the obliques and rectus abdominis, making the exercise far less effective.
  • Holding your breath during the crunch — this spikes intra-abdominal pressure unnecessarily; exhale on the way up to support proper core bracing and protect the spine.
  • Fully relaxing your abs between reps by letting your upper back collapse flat on the mat — losing core tension at the bottom removes much of the muscular load from the obliques and rectus abdominis.

Häufig gestellte Fragen

What muscles does the twisting crunch work?

The twisting crunch primarily targets the obliques — the muscles running diagonally along the sides of your waist — while the rectus abdominis (the front abdominal wall) acts as a synergist to flex the spine on the way up.

Is the twisting crunch good for beginners?

Yes. It requires no equipment, uses a small range of motion, and can be performed at any pace, making it accessible for beginners. Start with slow, controlled reps and focus on feeling the obliques contract before adding volume.

What is the difference between a twisting crunch and a regular crunch?

A regular crunch flexes the spine straight up to target the rectus abdominis. The twisting crunch adds rotation, shifting the emphasis to the obliques while the rectus abdominis still assists — making it a more complete core exercise.

How many sets and reps should I do?

For general core strength, 3 sets of 10–15 reps per side is a solid starting point. Count each shoulder rotation as one rep and alternate sides each rep, or complete all reps to one side before switching.

Where should I feel the twisting crunch?

You should feel the work primarily in the sides of your waist — the obliques — with some tension across your entire abdominal wall. If you feel it mainly in your neck, your hands are pulling your head forward rather than supporting it.
