Skeletal muscles work in pairs because muscles can only contract (pull) and cannot expand (push). Thus, if you want to move one direction, you use one set of muscles and to move in the opposite direction you use the corresponding set of muscles.

Skeletal muscles will have a flexor and an extensor.
The flexor bends the joint.
The extensor straightens it out again.
