2; The Bicep and the Tricep
Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
I think what your after is called an antagonistic pair of muscles, for example the bicep and the tricep. When the bicep is contracting the tricep relaxes and when the tricep is contracting the bicep relaxes.
bicep
bicep- it bends the arm while the triceps straighten the arm.
the bicep thank you
The calf muscles Xd
Muscles can only pull not push. That is why they work in pairs an example is your tricep and bicep, your bicep pulls your arm up and your tricep pulls your arm down.
The bicep curl obviously helps the Bicep but it also helps you triceps as you pull your fist towards you your are contracting your bicept and relaxing your tricep
crunches bicep curls
