I Want to Help You Become a Better Physical Therapist or Fitness Professional

With all the information out there these days, it’s easy to get overwhelmed.  I get it, I was in your shoes too.

Who do you turn to?  Who can you trust to help guide you?  And to me, social media is only making it worse.   Who actually has experience and is not just trying to act like an expert online?  I shake my head daily at some of the things I see.

I’ve got a ton of experience (which is just a nice way of saying I’m getting old…) working with injured people looking to restore the performance, as well as healthy people looking to optimize and enhance their performance.

I’ve been a physical therapist, athletic trainer, strength and conditioning coach, and performance enhancement specialist for over 20 years.  After working for many years with such prestigious organizations such as The Boston Red Sox, The American Sports Medicine Institute, and Massachusetts General Hospital, I co-founded Champion Physical Therapy and Performance in Boston, MA, where I help people get the most out of their bodies every day.

But I’m not just in the trenches working with people, I also conduct clinical research, have dozens of journal publications, and educate people all over the world.


This website is where I have been sharing my research, experience, and thoughts behind how I integrate rehabilitation, fitness, performance training, and sports medicine for over 10 years.

My goal is simple…

Share what I have I learned over the years, what I have tried, and what I have found to work in my hands.  I hope this helps give you a shortcut in your career.

But I’m also going to share what I am currently learning today because I believe we should always be pushing ourselves to grow and become better.  I continue to grow every day and want you to grow with me.


I have a handful of principles I follow in my educational style.  If these resonate with you, you’re going to be happy here and learn a ton:

Always Keep an Open Mind and Strive to Keep Growing

I can’t tell you how many times I’ve changed my thoughts based on new evidence or experience.  This is how we keep growing.  I often feel like people are too aggressively taking a stance, which causes them to defend their opinions rather than keep an open mind.  As research comes out, they’ll cherry pick what they learn based on what confirms their beliefs.  They often attempt to educate others by aggressively attacking anyone with a different opinion.  I prefer to educate by teaching you what I do, not what I think you are doing wrong.  I always say I’m pretty sure people will be laughing at us one day because we thought the earth was round!  :)

Always Know the “Why”

This is a principle I have followed my entire career and led to most of my research projects.  I’m never happy with doing something because “that’s how we’ve always done it” or because “that’s how someone taught it to me.”  I always challenge myself to know the “why” behind everything we do.

Combine Current Evidence with Experience

My goal is always to make the complex more simple.  As new evidence comes out, we need to add that to our existing experience.  This is how I approach every new journal article I read.  What can I take from this new study?  How will it change what I do?  What are the clinical implications?  It’s hard to do this without a bunch of experience under your belt.  That’s why I share it with you.


Good.  Let’s get going.  Click the button below to get started and check out my award-winning blog, my top-ranked podcast, and all my acclaimed online educational programs.  Or keep reading below to learn more about me and my website.

How This Website Began

I remember when I was first getting started how daunting everything in our profession seemed.  We all learn the basics in school but then get thrown out into the real world to fend for ourselves.  It takes times to get comfortable.

I was super lucky to surround myself with great mentors that helped me along the way.  But I hear from so many people that they don’t have a ton of people to learn from every day.

That is exactly why I started this website – to help others grow and stay current.  To take new research as it comes out and discuss the clinical implications.  To combine what limited evidence we have with experience.  To make the complicated more simple.

My plan from day one was to share my journey with you by writing about what I am learning and how this is changing what I do every day.

Today, everyone wants to be an expert on social media, but I always advise our students and interns to not try to “fake it ’til you make it” and try to proclaim expertise online.  It’s easy to spot a lack of authenticity.  Rather, just humbly share your journey and what you are learning.

I’m not going to lie, though, I started this website for me.

To keep me sharp, to keep me growing, to push me to never stop learning.  I always recommend others get into education for these reasons. Either through clinical research or simply just taking students and interns.  Honestly, it helps you as much as the person learning from you.

I started my career off as a physical therapist in a high pace outpatient clinic. I spent my spare time in the evening conducting clinical research, and then my spare time on the weekends traveling around the world teaching.  It was an amazing experience and something that really made me grow as a clinician during the first years of my career.

Then a funny thing happened.

I actually landed my dream job with the Boston Red Sox.

While this was exactly what I wanted to be doing every day, I literally worked every day (all day…) and stopped teaching.

I simply couldn’t.  There was no time.

After a few seasons in professional baseball, I felt that I was getting stale.  I started trying to figure out a way I could continue to educate because I missed it so much, and I missed how much it pushed me to keep growing.

I actually remember the day I decided to start this website.  I don’t think I ever told anyone this story before…

We were in Yankee Stadium, and I walked out of the clubhouse into the dugout during the game.  I sat down next to the other athletic trainers and I clearly remember asking them, “hey, do you think people would want to read a website if I review journal articles as they come out?  Would that be helpful?”

That was it.  What a ride it’s been.

I found an image of one of the early versions of the website (very web 1.0 haha):

Mike Reinold Original Blogger Website

Take a closer look and notice I had under 500 readers and 219 twitter followers hahaha! And people love cracking up at Lenny and me from some of our earlier work:

While my site has changed a lot and I personally got LASIK surgery, dropped a few pounds, and even started wearing modern slimmer clothing, I’m pretty proud of how the content has remained consistently impactful for people for over 10 years and 1000 blog posts.

I have consistently published ~2 articles a week for over 10 years.  The website is visited by 2 million people around the world each year and has won numerous awards.  We’ve expanded to have a ton of video content on Youtube, a top ranked physical therapy podcast, and now a dizzying amount of micro-content on my social media accounts like Instagram each and every day.  And I have slowly developed a ton of great online courses for people to learn from me at any time, from all over the world.

But most importantly, I’m still having a blast!  Because I am still learning and still growing. And now YOU are the one pushing me.  So while I admit I started this website for me, I sure hope you’ve learned from it as well.

Thanks for joining me on this journey!

Get to Know Me a Little

Before we get into all the boring and stuffy professional biography stuff (it’s at the bottom of this page), I wanted to share some random things about me.  We are all connected more and more each day through the internet and social media.  I meet people all the time that I feel I “know” because of our interactions online.  Many of you have been following my work for over a decade.  I wanted to give you an opportunity to learn a little more about me.  This should be fun…

Some Interesting Professional Tidbits…

I never bought my neurology and pediatrics textbooks in college

Shhhh…. Don’t tell Northeastern!  I used the book money to buy James Andrews and Kevin Wilk’s textbook on Injuries in Baseball.  I just went to the library a lot that semester, but spent time learning more about what I was passionate about. This book started it all for me, and led me to seek out Kevin and Dr. Andrews so I can keep learning from them.

I wrote a proposal for the first dual major PT/ATC program

I was a freshman at Northeastern University. It was approximately a 10 pages outline how I would pull off the dual major, still pay per credit to make the university money, and graduate with both degrees. They didn’t go for it, and I’m pretty sure they thought I was crazy. It was probably a good thing because that would have been hard! But it’s nice to see that some of these programs exist now. Luckily, I got my hours and took some classes at Tufts University and Sanford University to get my ATC certification.

I failed the Athletic trainer boards the first time

This one is for all the students. Yup, I failed. At the time there was a practical portion. I flip flopped Adson’s and Allen’s thoracic outlet tests and I didn’t imaginarily “wet” the sponges for the carbon ESTIM pads. Seriously. This was obviously a long time ago. I reminded the examiners that sponges were no longer something we could use because each patient needed their own set of ESTIM pads, we couldn’t reuse the sponges for sanitary reasons. They didn’t seem to care, and they still failed me haha. BTW, remember those nasty yellow sponges?

I’ve turned down jobs with several MLB teams

Both before and after the Red Sox. And other professional sports too. These were extremely hard decisions but they always work out if you make the decision for the right reasons. Sometimes saying no is the right long term move, but it’s hard in the moment. It was really hard to turn down Theo Epstein and move to Chicago to join the Cubs. Theo is brilliant and the best person I’ve ever had the opportunity to work under in any situation. But I’ve also been fortunate to have found some jobs that did “fit” for me with the Boston Red Sox and now the Chicago White Sox.

Some stuff about my personal life…

I have an amazing wife and two awesome daughters

They are super supportive of me. Every guy should have a daughter. I got two. See above reference to the “right reasons” for why I didn’t move to Chicago. A good friend of mine once gave me the best advice I could ever pass on. He said, “Mike, when it’s all said and done, no one’s going to remember what you did in your life more than your family.”

I’m a youth softball coach in my town

I coach my daughters’ softball teams. It’s an absolute blast and I really recommend you get involved in youth sports if you have kids. It’s an awesome experience to take a group of girls that know nothing, and spend several years slowly developing their skills. Oh, and the real secret is to just give them Double Bubble and eye black.

We had a dog for 16 years

We got an awesome dog when my wife and I living in Birmingham when I was working at ASMI. We wanted to name her something related to Boston, so named her Dunkin. Us Bostonians have a soft spot for Dunkin Donuts coffee. She actually loved the move back to Boston, and we’ll never forget the first time she saw snow. Instant love. She lived a long life, and is missed by the entire family!

Lenny Macrina and I were neighbors growing up

Funny that Lenny Macrina, my co-owner of Champion, and I have known each other our entire lives. Pretty crazy to think we were stick ball partners, then he was my PT student, and eventually my co-owner of an amazing business.

I’ve won a Little League, Pony League, Adult Recreational Softball League, and World Series Championship.

Sure, the last one probably puts it over the edge, but I’m proud of it all, especially the walk-off bunt in Little League when I was 10.

Some odd things about me…

I’m not a big fan of heights

My wife says I giggle like Beavis and Butthead when I’m on a roller coaster. I can do the medium roller coasters, but no way am I going on a ferris wheel.

I have really sensitive boney prominences

Don’t even think about touching my ASIS’s, I’ll literally punch you in the face.  It’s a reflex. You’ve been warned.

I am getting more into local coffee roasters

I feel like everyone writes “coffee lover,” or “coffee addict” on their social media profiles. I’m actually not a big Starbucks fan, I don’t love the burnt taste. I’ve been dabbling in different local roasters and coffee origins. It’s crazy how much is out there when you only drink Starbucks or Dunkin. I really recommend you check out George Howell Coffee.

I think everyone should own three things

1) TempurPedic pillow, 2) Sonicare Toothbrush, and 3) Smart Wool socks. Just saying… You’ll thank me.

Some useless things I’m good at…

I started playing guitar in my 30’s

I remember wanting to learn something new that could stimulate my brain that wasn’t related to PT or strength training. I was trying to decide between learning guitar or how to speak Spanish. I love music, so picked guitar. Man, that was a bad first month but I remember the first time I played a song I liked and could recognize it, the beginning of Pearl Jam’s Corduroy. I was sold.

I’ve won some fantasy football Super Bowls

I don’t want to go as far as to say it’s a “dynasty” like the Patriots have with Bill Belichick, but I do wear his infamous hoodie in the winter. This just probably comes down to the fact I put the time in each week to research. I have many fantasy Super Bowls under my belt.

I’m pretty good at NHL 95 on the Sega Genesis

I’m not sure why but I can score 20 goals without trying, especially if playing as Keith Tkachuk. Remember the wrap around move? If you know it, you know what I’m talking about. We all have talents in this world, I guess that’s one of mine.

You can’t beat me in Fruit Ninja

Another odd skill that serves me no benefit in life. What’s your high score?

Some crazy things i’ve done…

I’ve been in the Pearl Jam vault

If you followed me online, you can probably tell I’m a big Pearl Jam fan. I’ve been extremely fortunate to get to hang out with them several times, including in Seattle. I once visited their warehouse with their studio, tour gear, and rehearsal space. It was awesome. I got to go into their recording vault and held the original recordings of every take of Alive (there were a lot of takes). I wanted to listen to them all.

I’ve wrestled in a WWE ring

We rehabbed a lot of WWE athletes in Birmingham and we actually installed an official ring in the biomechanics lab at ASMI when rehabbing Triple H. I’ll dispel the rumor that the rings are padded, it’s like a 1 cm pad on top of straight wood. But jumping off the ropes like Superfly Snuka was worth it. Oh yeah, I’ve also been on Wrestlemania before.
