Why is strength training so important?

Most obviously, strength training makes you stronger. It does this in several ways, including:

• building muscle tissue
• improving inter- and intra-muscular coordination — in other words, the ability to coordinate your moving parts
• improving rate of force production — how quickly you can generate force to move against the resistance
• strengthening connective tissues such as tendons
  

It can also make your muscles bigger while creating a demand for blood delivery, engaging the cardiovascular system.

How else can strength training be useful?
