Do you ever stop to think about all of the amazing things your body does for you?
It gets you up and moving in the morning, physically taking you through getting ready for the day while you mentally warm up.
Your body takes you from point A to B to C and all the way down to Z in a day.
Your body welcomes the stress presented and does whatever it can to keep you functioning.
Personally, I take it for granted, and typically only point out what it “cannot” do or how it is “failing” me.
But when I really look at it all and think about why I cannot do something, I can always find the answer.
My body has all the answers. Your body has all the answers. We just have to stop and look for them.
What are we looking for?
Our body gives us surface level answers like weight and body composition, but the answers we’re searching for lie beneath the surface.
You wake up in the morning and head right to the bathroom scale only to find that number to be the same as the last week.
Then you head to the gym set on grinding hard with the hope of FINALLY dropping that number on the scale.
After your workout, a glance in the mirror shows that your stomach still isn’t flat after that core blaster workout and the gym scale still shows no change.
On the surface, there’s no change, but what’s really happening to your body during as you diet hard and push yourself to the max in your workouts?
Did you check in and really ask how your body it is feeling?
Did your body feeling recovered when you woke up? Or was it sluggish, sore, and tired?
How many hours of sleep did you get the night before? Was it restful?
What was your nutrition like the day prior? Did you eat too much? Too little?
These are all questions you need to be asking yourself to better understand why those surface level factors stay the same.
These are measures of biofeedback.
Biofeedback is the hot new thing many coaches, including myself, claim will get you the results you want.
So what is it?
Biofeedback is a full body assessment and a representation of the different signs presented by the body to identify how well (or not) we are functioning. It is a check in with the metabolic portion of our body that helps to indicate whether your body is ready for more, content with where it’s at, or that you have gone too far.
There are numerous ways to evaluate biofeedback, but here are the 6 that I utilize with every client to help set up his or her program:
Too Hungry
Too Full
Cravings
Our body has all of the answers.
Yes, the scale matters.
Yes, progress in the gym matters.
Yes, body composition matters.
These are goals you have set, so they are important; however, if you’re only focused on the surface level information, dieting harder, and grinding in the gym you will get tired of lack of results and feeling like dirt.
Results cannot last when you only focus on the surface level information.
Biofeedback has the information we need to create and modify programs that keep us on track for results AND feeling great.
I will never guarantee you results, but if you start to regularly check in with these biofeedback markers, I do guarantee you will begin to view your body in a different light, one that takes you beyond the surface and to closer to an overall healthy lifestyle.
