What does muscles work in pairs mean?
Skeletal muscles are arranged as opposing pairs because, although they can shorten themselves by contracting, they have to be stretched back to their former length by other muscles. An example of opposing muscles is in the arm, where the biceps and triceps have opposite actions. As one muscle shortens, the other is stretched. The biceps contracts to bend the arm at the elbow while the triceps stretches. To straighten the elbow joint, the triceps contracts, while the biceps stretches.

Why can you bend your arms?
When you bend your arm your brain send signals to your arm muscles telling the biceps, your upper arm muscles, to contract, go taut or stretch, while telling your triceps, lower arm muscles, to relax, become less tense or ease. Both of these muscles act as an antagonistic pair and work together to bend the arm. Each muscle uses the bones in your arm, the Humerus, the ulna and the radius, as an anchor.MonkeyLover-Dinda

Why do muscles need bones in order for the body to move?
AnswerThough not all muscles work in pairs, the general principle is that one muscle moves a bone one way, and the other muscle moves it the opposite way. Why? Because muscles can only pull, not push.For example, when you bend your arm, the biceps muscle pulls. When you want to straighten it, the biceps muscle cannot push it back. Instead, the triceps muscle that's on the back of the arm pulls in the other direction.
