Do you find it odd that when something is true we can assign meaning, analyze, and then evaluate it, but when that same thing is even just a little bit off, it’s not even slightly useful for the same tasks? I do.

How useful is a calculator that’s off by “just a little” when doing your taxes? It’s all-the-way useless.

It’s like the whole set-your-clock-five-minutes-fast trick. The most useful clock is the most accurate one. If the time on a watch is extremely accurate, it’s extremely useful. Conversely, setting your clock five minutes fast in order to increase productivity or “guarantee I’m on time” usually results in two things. First, the clock’s owner knows the time is inaccurate and, second, the clock’s owner often has to do more work calculating how much time they really have to get to work.

I’ll be the first to tell you that class at Reviver isn’t the seventh game of the World Series (although sometimes when Vince says “HI!!!!!!!” when you walk through the door, it does feel pretty special…….. thanks Vince!) but since we are here and working hard, we might as well get some accurate information about our work. If you choose, you can then assign meaning to, analyze, and evaluate this info. It’d be tough to improve on an effort that can’t be accurately measured, right? So, in order to have something to measure against, we assign specific range of motion standards, rep schemes, and loads. Except, once you cut a rep short, (say not squatting to depth or missing the lockout on a push up) the statement of what occurred in that day’s training isn’t true anymore. Not only is it not true, it’s not even measurable anymore.

When the integrity of the information is lost (even just a little), we lose everything. What does it mean when you run a 400m run in one minute and fifteen seconds, but only go to the corner (rather than the full distance)? Who knows, should we measure that distance? Should we take a mental note that you have a hell of a 389.63m run time in you? It doesn’t seem worth it to run all that way for zero information in return.

Movement integrity is an all or nothing game. When your chin doesn’t get over the bar, well, I don’t even know what to call that…. A pull u? A pu up?? My message here is to calibrate your watches with movement integrity. Even if it’s for nothing more than selfishly getting some useful information out of your effort that both you and the coaches are able to use in the future.

Happy Anniversary ReviveR

By: Coach Sammie

We are celebrating CrossFit Reviver’s 6th anniversary tomorrow! That might not seem like a long time to some, but in a culture where people are bored easily, want constant change, and are always looking for the next, new, sexy exciting endeavor… it can be quite the challenge to grow a success business in the fitness field. I joined CFR about 5 1/2 years ago, 4 months after they opened, and have had the pleasure to watch it grow and transform into an organization and community that I am so proud to be a part of. Through years of experience and a constant pursuit of education the evolution of Reviver from day one to now is incredible. Thank you to Jeremy and Vince for having a dream and working hard every single day to make that dream a reality. You took a carefully thought out plan, set it into action, and constantly critique it to become better everyday. Thank you to all of our members for your continued trust and loyalty. Every one of you is an amazing human being with the power to improve your life and create your own happiness. Each day I get to walk in here and have the honor to help you tap into your own potential gives me so much joy. I am incredibly proud of all of you. This has been such a wonderful journey so far and I cannot wait to see what the next 6 years has in store for us 🙂

Here’s a quick look at where we started 6 years ago and where we are today!

Hopefully you have noticed the giant banner in the gym. We put our mission statement on this banner as a reminder to all of us of what we are a part of. Most people that join our gym do so because they want something new and fun for their FITNESS routine. They stay with us because of the progress they have through our EDUCATION and because of the relationships they built through our COMMUNITY. If you have been with us for a year or more then you have most likely what you have experienced. This is a cycle, meaning that at certain points of your journey, you will be affected by these 3 aspects.  Our hope is that every time you go through the cycle you have a little bit more fun with your Fitness, evolve with us and through us in your Education, and connect deeper and wider with our/your Community.

Why Adequate Sleep Is So Important

By: Coach Gannon

Hey Reviver Nation!! So as you have heard each one of us coaches preach, it is about what you do the 23 hours outside of the gym that really is going to affect your fitness journey. This includes your Sleep, Stress, and Nutrition. Today, I wanted to spend a little time focusing on how your sleep affects your body’s function. It seems like in our current society sleep has unfortunately become a luxury and when a person attempts to make it a priority, they are often looked at as being lazy or weak. The ironic part is, people who don’t get adequate sleep are actually becoming weaker, and lazier because their body is not recovering properly. Even if we looked past the compromised protection and increased risk of degenerative disease and early death afforded by poor sleep, inadequate sleep negatively affects our ability to build strength, lose weight and gain muscle.

Proper sleep helps to regulate a growth hormone called cortisol, cortisol is a steroid hormone, that when released into the blood, is transported all around the body. Almost every cell contains receptors for cortisol, so cortisol can have lots of different actions depending on which sort of cells it is acting upon. Cortisol levels are suppose to be at their highest level right when you wake up, and then taper off throughout the day, ending with low levels at night. If someone does not get adequate sleep, these levels can start to fluctuate and become erratic. This can cause some negative effects on the body including inhibiting control of the body’s blood sugar levels (which regulate metabolism and fat storage), decreasing anti-inflammatory properties (which help with recovery in the muscles so you can train the next day), influencing memory formation, controlling salt and water balance (bloating, cramping, and dehydration), and influencing blood pressure (which can affect the heart). Simply missing one hour of sleep per night than what’s optimal for you prompts your brain to secrete cortisol and shift your body away from muscle building and toward fat storage through higher levels of stress and lower levels of testosterone. So as you could imagine as these inadequate hours of sleep build up over days, weeks, and even years, our imbalances become so great that the deficits cannot be made up through diet, and fitness alone.

A study done by The University of Cambridge showed that even in the healthiest men, and women a poor night’s sleep is seen to result in temporary glucose intolerance (insulin resistance). If your body does not produce enough insulin or your cells are resistant to the effects of insulin, you may develop hyperglycemia (high blood sugar), which can cause long-term complications if the blood sugar levels stay elevated for long periods of time. In fact, consistent sleep deprivation has been seen to result in an 18-20% decrease in leptin, which is a hormone produced by fat cells that helps in the regulation of body fat. Leptin also interacts with areas of the brain that control hunger and behavior (and signals that the body has had enough to eat). It was found that there was a 24-28% increase in ghrelin, which is a hormone that is produced and released by primarily the stomach. Ghrelin is termed the ‘hunger hormone’ because it stimulates appetite, increases food intake and promotes fat storage.

Sleep can affect so many functions in your body. In order to make changes in our sleep habits, we must first figure out what might be preventing us from getting adequate sleep in the first place. To help with this, I have attached a video below where Dr. Charles Czeisler explains why we’re sleeping less than we did a generation ago, and the damaging effects it’s having on our health.


August – Athlete Of The Month


Steve Fehlinger, 65, Recently Retired, Rochester Hills.

When did you start at Crossfit Reviver? :   01/02/2016

What is your athletic background?: Worked at a gym a couple of years while in college and took a weight lifting class in college as well. I did some moderate exercising over the years and eased into CrossFit in August 2013.

What is your favorite and least favorite WOD / movement?: Favorite is probably pull ups. Least favorite is running.

What is your greatest accomplishment? Personal, professional and fitness related. : Personally, raising three great kids (2 sons pictured above, and 1 daughter not pictured). All of which are college grads, successful and they stay physically active. Professionally, I have two graduate degrees and in the last several years realized I had a knack for writing. I have several articles published in professional newsletters both here in Michigan and Illinois. Fitness-wise, I completed three Murph workouts! The last one was while in physical therapy for a frozen shoulder which is currently a work in progress.

Has CFR made you better? If yes, how so? : I was less informed about the importance of mobility before joining CFR. In fact it was one of the coaches at CFR, that pointed out that one arm did not flex at the elbow completely; I was completely unaware of this. After receiving some advice from a physical therapist, I have got the mobility almost where it should be.

What are your hobbies? : Fitness, nutrition, tennis, golf, biking and posting comments in the Wall Street Journal op-ed pages.

What are your Top 5 favorite movies? : Shawshank Redemption, Search for Red October, The first God Father movie, The Wizard of Oz (there is more to this), and Ghost.

What is one thing we don’t know about you?: I have almost always had a car with a manual trans. My first four cars had a manual trans. I bought a car for the kids and of course it had a stick, so two of the three know how to drive a car with a stick. I had a hot rod mustang by the time the third one cane around, which was a challenge and lost patience with the last one.

What are your goals in life? Personal, professional and fitness related. : Personal goals are to stay fit and spread the word on nutrition. Professionally, take full advantage of reaching retirement which includes being healthy enough to keep doing what I like to do for as long as possible. Last year at this time, I did 17 consecutive pull ups, so once my shoulder gets back to where it should be, my intermediate goal is to do 20 unbroken and one at 133% of my weight. Longer term, being able to do a muscle up would be cool!
