How Do Muscles Work in Pairs to Create Movement?

Muscles work together in pairs, which we call antagonistic pairs, to help us move. Here’s a simple breakdown of how this works:

  • Flexors: These muscles tighten up to bend a joint. For example, when you lift your arm, your biceps are flexing.

  • Extensors: These muscles relax while the flexors are working. Once the flexors are done, the extensors kick in to straighten the joint, like when your triceps help extend your arm.

This back-and-forth between flexors and extensors is really important for making our movements smooth and controlled!
