Sir Isaac Newton
What the hell does Sir Isaac Newton have to do with fitness and exercise? Well outside of his “discovery” of gravity, he had three laws of motion. And his laws of motion can actually be applied to you getting off your butt and get you moving.
Think about gravity. You rarely think about it because it’s just a given, but when you’re training, you are constantly working against gravity. Every weight you lift, every movement you make, gravity is working to bring you down. It’s up to you to get stronger and beat gravity.
Go back to high school physics class. I actually loved physics, it was one of my favorite things, and as it turns out, exercise is a lot of physics. I mean the body is one giant lever system. How cool is that?! Have you ever thought about that as you exercised? Probably not, but that’s just the nerd in me.
Anyway, Newton’s Three Laws of Motion are:
- First Law-Law of Inertia: Body at rest will remain at rest; Body in motion will remain in motion until outside forces act upon it.
- Second Law- Force = Mass*Acceleration: More mass means more force is required to accelerate.
- Third Law- Law of Reaction: For every action, there is an equal and opposite reaction.
“What is often the hardest thing when it comes to fitness & nutrition?”
Getting that motivation to start, to take that first step. To get past the “one days” and the “somedays.” You know what I’m talking about. The perpetual cycle of one day I’ll start my diet, or someday I’ll start exercising. But you know what? That day never comes till you make a conscious decision to do it.
Newton’s First Law of Motion is the law of inertia. It states that “a body at rest tends to remain at rest, and a body in motion tends to remain in motion, at the same speed and in the same direction, unless acted upon by an outside force.”
In other words, the longer you stagnate; the longer you remain at rest, then the longer you will stay at rest, the longer you will stagnate, and the harder it will be to get started.
Think of a rock at the top of a hill. It’s going to stay there till some outside force acts upon it to get it rolling downhill. You are that rock. You’re standing at the top of the health and fitness hill waiting to get started; all you’re looking for is that spark, that motivation to get you rolling.
According to Newton’s First Law, once you get that ball rolling, like eating healthier or starting a training program (ahem AMP), it’ll stay in motion.
So get that rock moving!!
Newton’s second law is all about force. Force is equal to mass times acceleration. You can look at this in two ways. You can see a weight in front of you, let’s say when you’re deadlifting, and you’re going to have to put a significant amount of force into the bar and into the ground to accelerate or lift it up.
Additionally, your goal may be massive. Whether it’s losing weight, or putting on muscle, or getting faster, it may look like a big undertaking. The key is determining how much force you want to put into you goal or how much effort you want to put into it. How much are you willing to push to get to where you want to be?
Put some force into what you want to accomplish. The more force, the more effort you put into your goals, the quicker you can see your results accelerate.
Newton’s third law is commonly referred to as the law of reaction in that every action has an equal and opposite reaction. Applied force is accompanied by an equal and opposite reaction force. Say it with me, “every action has an equal and opposite reaction.”
If you put in the work, if you apply force to what you want to do, there will be an opposite reaction, meaning that there will be results. This can also work the opposite way. If you don’t put in any work, you’ll see an opposite reaction. One of stagnation and plateaus, or worse, regression.
Each decision you make every day whether it relates to what you eat, when/how you exercise, how much sleep you get, how you deal with you stress, all will have an equal and opposite reaction towards your results.
