Taking the First Step in the #Fit4Yu Fitness Program

Posted on Updated on

fit4yu-commit to live fit

Society now knows how to react when people are talking about living fit and healthy.  You may even have had the greatest of intentions for working out or calling that personal trainer. But did you know that saying, “I have NO time 4 exercise” is really saying is “exercise isn’t my priority.”  Everything in life involves changing our lifestyle to what revolves around what we value most. If you aren’t finding it in your heart to exercise, just consider the people around you that need and love you.  I encourage you 2 be your absolute best 4 them in every aspect.

Maybe you’re asking how?

I’ll take care of that–just come see me about taking that first step.  You’ll find that your health was just one aspect of an even bigger picture.
contact me–I look forward 2 meeting you.

Am I losing weight or mass?

Posted on Updated on

Weight vs Mass

Unfortunately, when most of us feel uncomfortable in our body we focus on losing the weight rather than mass. So, why does knowing the difference make a difference? I’ll explain.
The mass of an object is the amount of matter that something is made up of. The weight on the other hand is simply related to the force by which gravity pulls that mass. So, if you’re dieting (successfully) you are losing mass. You are literally shedding matter off of your body and since there is “less” of you to pull by gravity, you are getting pulled with less force. When you step on the scale, there is less force pressed against it so it shows a lesser weight.
In a nutshell: Your WEIGHT is equal to your MASS times the GRAVITY of the Earth.

So basically, if you are a person weighing about 150lbs and you ship yourself to the moon, your weight will change (to 25lbs) because there is less gravity on the moon. Your mass hasn’t necessarily changed since you didn’t actually lose that weight.
REMEMBER: You want to lose MASS, NOT just weight. That is really what you want to feel better in your clothes. Your weight is simply a measurement of how much mass was lost.
You may ask: is this really so important to know the difference? Yes!
When you workout in my #FIT4YU sessions you will gain muscle- which means you will start to gain a good healthy weight. If you don’t understand this you will think your weight must always go down and become discouraged when really you should be patting yourself on the back!
