This activity will focus on how eccentric and concentric muscle groups work together to allow us to move, lift, and use different muscles to perform different actions. The muscles in our arms work opposite to each other in order to prevent over corrections and extensions. When you pick up a cup of cocoa, you use muscles that contract, and you have muscles that extend.
