Introduction to the first principle

As we saw earlier, the key to stimulating maximum muscle growth is to not only recruit, but also to fatigue the high-threshold motor units (HTMU). HTMU are also known as type II motor units, fast motor units and glycolitic muscle fibers. There are several different terminologies to describe the different types of motor units/muscle fibers, so weeding through the literature can get confusing. Without going into the depths of theoretical physiology, It is important to have a better understanding of what exactly motor units are and how they are recruited. When we understand how to stimulate these fibers we will be better equipped to design optimal growth training protocols.

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
