The hand opposite knee crunch is a bodyweight core exercise that targets the obliques and rectus abdominis. By driving one hand toward the opposite knee, it adds a rotational element to the standard crunch, training the abs to both flex and twist the torso. It needs no equipment, making it an easy finisher or warm-up for the waist.
Hand Opposite Knee Crunch: So führst du sie aus
- 1Lie on your back with your knees bent and feet flat on the floor, hip-width apart.
- 2Place your fingertips lightly at the sides of your head, or extend your arms toward your thighs.
- 3Brace your core and press your lower back gently into the floor.
- 4Curl your shoulders off the floor and rotate your torso, reaching one hand across toward the opposite knee.
- 5Squeeze your obliques and abs at the top of the movement, holding briefly.
- 6Lower under control until your shoulder blades return toward the floor without fully relaxing.
- 7Repeat for the chosen reps, then switch to reach the other hand to its opposite knee.
- 8Finish the set, then relax your back flat on the floor.
Technik-Tipps
- Exhale as you crunch and twist; inhale as you lower back down.
- Lead the rotation with your shoulder and ribcage, not by yanking your head with your hand.
- Move slowly and deliberately so the obliques do the work instead of momentum.
- Keep your lower back lightly pressed into the floor to protect the spine and keep tension on the abs.
- Balance the reps evenly between sides so both obliques are trained equally.
Häufige Fehler
- Pulling on the head or neck with the hands, which strains the neck and takes work off the abs.
- Using momentum to swing up instead of rotating slowly, which removes tension from the obliques.
- Lifting the whole back off the floor like a sit-up rather than curling and twisting, which loads the hip flexors instead of the core.
- Holding your breath through the rep, which raises pressure and reduces core control.
- Training one side far more than the other, creating an imbalance between the obliques.
Häufig gestellte Fragen
What muscles does the hand opposite knee crunch work?
It targets the obliques and the rectus abdominis. Reaching one hand toward the opposite knee adds rotation, so the obliques work alongside the front abs to twist and flex the torso.
Is the hand opposite knee crunch good for beginners?
Yes. It uses only body weight and a small, controlled range of motion, so beginners can start with a few slow reps per side and build up as their core gets stronger.
How many sets and reps should I do?
A sensible default is 2 to 3 sets of 12 to 20 reps per side. Focus on a slow, controlled twist rather than chasing high numbers.
How is it different from a standard crunch?
A standard crunch flexes the torso straight up and mainly hits the rectus abdominis. The hand opposite knee crunch adds a cross-body twist, bringing the obliques into the movement.
Why do I feel it more in my neck than my abs?
That usually means you are pulling your head forward with your hands. Keep your hands light at the sides of your head and lead with your shoulder and ribs so the abs and obliques drive the movement.
