abdominal crunch
MediumTechnical/Instructive; Common in fitness contexts.
Definition
Meaning
An exercise targeting the abdominal muscles, performed by lying on one's back with knees bent and lifting the upper torso towards the knees.
A core-strengthening movement in fitness and physical therapy that isolates and contracts the rectus abdominis muscle, often used for building core stability and muscle definition.
Linguistics
Semantic Notes
Specific term within exercise physiology and general fitness. Implies a controlled, small-range motion, distinct from a full 'sit-up' which has a larger range of motion and can involve hip flexors.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'abdominal crisis' or 'abdominal crash'. The word 'crunch' here refers to the crushing/squeezing motion, not a sound or disaster.
- Not to be confused with 'пресс' (the press/exercise) alone; 'abdominal crunch' is a specific type of exercise for the 'пресс'.
Common Mistakes
- Pronouncing 'abdominal' with a strong 'doh-MAIN' sound (correct: dom-in-al).
- Confusing it with a 'sit-up'. A crunch has a smaller range of motion.
- Using plural verb for singular form: 'Abdominal crunch are...' (incorrect) vs. 'The abdominal crunch is...' (correct).

FAQ
Frequently Asked Questions
A crunch involves a smaller range of motion, lifting only the shoulder blades off the floor, primarily isolating the abs. A sit-up lifts the entire torso to a seated position, engaging the hip flexors more.
When performed with correct form—keeping the lower back pressed to the floor and avoiding pulling the neck—they are generally safe. However, individuals with pre-existing back issues should consult a professional.
Quality over quantity. Focus on proper form and controlled movement. Typically, 2-3 sets of 10-15 repetitions is a standard starting point, but it depends on your fitness level and overall programme.
Muscles need time to recover. It's generally recommended to train the abdominal muscles 2-4 times per week, allowing for rest days, just like any other muscle group.
