Muscles never "push"; they can only "pull".
The only power that muscles have is to contract or relax. When they contract, they pull. Most bones have two or more sets of muscles, and each muscle pulls in one direction; in sets, the muscles can work together or oppose each other, which account for all the actions that an animal or person can perform.
Bones in a joint move by the contraction and relaxation of muscles attached to them. The movement is facilitated by the friction-reducing synovial fluid in the joint. The type and range of movement depend on the specific joint and its structure.
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.
Muscles contract and relax to pull/push
the muscles are around or next to the bones, the contracting of muscles enables the bones to move. for example the muscles in your arm, when you move your arm up, the muscle underneath the bone contract (tighten) to push the bone upwards.
When you jump up your muscles in your legs exert a force on your bones to push you off the ground. The muscles are attached to the bones to have leverage. So when your muscle pulls, the leg bone moves on a hinge or joint and the bones push off the ground.
Muscles attached to bones contract and generate force, pulling on the bones they are attached to. This force causes the bones to move, resulting in movement of the body. The attachment of muscles to bones via tendons allows for efficient transfer of force and movement.
The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.

Your abdominals work hard when you swim. Also your legs if your kicking, and your shoulders push the water to move you forward.
