2. Biceps can also name a similar muscle at the back of the thigh. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/B/biceps/#m2)

### In the lessons

In science lessons pupils learn that muscles work in pairs: the biceps contracts to bend the arm, and the triceps at the back contracts to straighten it. In PE people «show their biceps» by bending the arm. Phrases: flex your biceps, biceps and triceps.

### Examples

### Note

«Biceps» is singular and plural at the same time: one biceps, two biceps. «Bicep» without «s» is common in speech but «biceps» is the correct form. «Bi» means two: the muscle has two heads at the top. Muscles only pull, never push — that is why they work in pairs.
