Rest Day & Newton's Law of Inertia

Newton's Law of Inertia (Also Newton's Fst Law) & Fitt's Law of Speed

Definition (From Wikipedia):
An object at rest remains at rest and an object in motion will remain in motion unless acted on by an unbalanced force.

Definition (From Dr. Paul Jures):
Fitt's Law says that speed and accuracy are inversely proportional.

Definition (From many sources):
When lifting an implement from any height there is initial slow phase to overcome the implement's inertia (first pull). Then when the implement is moving one can accelerate it as your body position and joint angles make that acceleration easier (second pull).

It takes a great amount of effort to get a bar moving in a clean, deadlift or snatch and hold one's body position and proper mechanics. If we take for granted that Fitt's law, then of couse we would want to at least start carefully (with carefully in this case meaning slowly) when hefting an object. But that is only half the story, The way I translate Newton's Fst Law to my clients and concieve of it for my own training is this: If you want to distort the position of an object at rest you must begin to do that slowly and then accelerate the object or risk distorting your body position.

In other words stop jerking the bar off the floor or out of the rack.
