Power considers how quickly you can use your strength. From a technical, physics standpoint, power is the rate of doing work. Hurling a heavy ball a short distance is not as powerful as throwing a lighter ball twice as far. And lifting the same barbell weight but taking longer to do it indicates less power.

But we do not need to be this technical to think of power in our daily lives. In our style of training, increased power is usually measured by how fast we can move our body around. For instance, we can can see how powerful we are by how high or far we can jump. Another example comes from fighting sports, where power is measured by how hard you can punch and kick.
