I emphasize the importance of biomechanics all the time, but I've never taken the time to define what it means, why it's important, and how to apply it to your exercise.
Check out my video I created here that teaches biomechanics for fitness instructors.
According to dictionary.com, biomechanics means "the study of the mechanical laws relating to the movement or structure of living organisms."
Let's break that down a little, because there are a few key terms within that definition.
Mechanical laws mean the laws of physics (remember Newton's laws from third grade?) that play into movement under different conditions. Each time you lift a weight, certain laws dictate how heavy it feels and how much "stress" will be applied to your system. This is important because it helps to provide a "framework" using mathematics to determine optimal exercise.
A second important term from that definition is the "structure...
