Before you start working out to build muscle, it's important to know how long it will take for you to see results.

During slow hopping, muscle fibers maintain nearly constant length. However, during fast hopping, they actively shorten even as force increases, displaying what they call negative stiffness.

Muscle fibers are divided into three types: slow twitch (type I) or red fibers due to the large number of mitochondria they possess, fast twitch (type IIb) or white fibers and intermediate (type IIa).
