When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
They are the muscles. Muscles contract in pairs to move the parts across the joint. One muscle contract with more power. The opposite muscle contracts with less power and get stretched over to allow the first muscle to act.
ussually, one muscle in the pair bends part of the body.the other muscle straightens part of the body.
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.

Skeletal Muscles
Muscles move body parts by contracting and then relaxing. Your muscles can pull bones, but they can't push them back to their original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.
The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.

There are more than 600 muscles that move together to move your body! ---Bones form the structure for our body, while muscles are responsible for pulling the joints, allowing us to move. The cartilage, muscles, ligaments, and tendons, all working as one holding bones together and letting joints move. Muscles connect the joints to the bones. Flexing of the muscles and the ability to bend at the joints moves the bones to accomplish skilled body motions?
