Meet your trainer, MACKENZIE HOWELL

​​Mackenzie Howell is the founder of Science Fitness Solutions, a private fitness training company located in Nashville, Tennessee.
 
His vision began to take shape when he decided to change his lifestyle and old habits.

After dropping over 100 pounds and transforming his mental and emotional states, he knew it was time to put roots down in a new place.  He left his hometown and moved to Tennessee to pursue his dreams. His intense discipline resulted in a leadership position at a well-known luxury gym in the United States. 

Although armed with a master's degree in exercise physiology, Mackenzie learned first-hand the gimmicks, fads, and lies found in the fitness industry. From this base, Mackenzie developed his company's mission:

To rebuild people's lives with truth and empower them to see that they are their own solution.
 
When the pandemic hit in 2020, Mackenzie was laid off like many others. He saw this as an opportunity to start his training business, and Science Fitness Solutions was born. The company's customer base skyrocketed within a matter of months. Mackenzie decided it was time to expand Science Fitness Solutions to help more people find their road to health and wellbeing.

I began my weight loss journey at 360 lbs at the age of 37.  I had gastric bypass surgery in July of 2017.  Science Fitness Solutions became my personal training team and kept me on the right path to health.  We trained cardio.  We trained strength. 

They taught me all about stretching, warming up, and cooling down. 

The time that Science Fitness Solutions put into personalizing my training astounds me.  Every time I saw them, there was a new workout.  A new element to master.  They helped me train for my first ever 5K.  And my second.  Also, the hardest thing I had ever done, up to that point, a Ragnar Relay race.  Twelve individuals teaming up to run from Chattanooga to Nashville, Tennessee.  In May of 2018, I reached my goal weight.  I was down to 190 lbs and was loving life."

​Before I began my journey with Science Fitness Solutions, I had been on a perpetual hamster wheel trying to lose the last of the (50!) extra pounds I had put on during both of my pregnancies.  With each attempt, any weight that I lost would inevitably return and then some.  I began to avoid taking pictures because of how uncomfortable I felt in my own skin.  My clothes no longer fit.  Fed up with being tired and feeling out of control, I decided it was time to ask for help.  In December 2019, I stepped on the scale during my first consultation with Science Fitness Solutions and I was horrified to see the numbers staring back at me…I was 189.3 pounds and 39.2% body fat! It was time for a change. 

Science Fitness Solutions helped me to evaluate my relationship with food and to understand its intended purpose.  I had always assumed that the more I deprived myself of calories and the more I worked out, the more weight I would lose.  I was shocked to learn that this approach to weight loss was actually working against me.  Science Fitness Solutions helped me understand that eating enough of the right foods would provide my body with the fuel it needed for the goals I was working towards.  I committed to trusting the process and to consistently show up even when I was really tired or really sore.  Thanks to Science Fitness Solutions, I was able to embrace and celebrate the concept of “progress not perfection” and that it didn’t have to be “all or nothing.

​The team at Science Fitness Solutions’ coaching and encouragement helped me to develop a lifestyle that was balanced, healthy and sustainable. Almost a year and a half later, I am proud to share that I have lost over 35 pounds and over 18% body fat. I have even managed to put on several pounds of muscle as well. There is no better investment than the one you make in yourself. Make today the day you decide that you are worth it!"

​Being overweight was never something I had anticipated happening to me. I went from being an extreme athlete to a 225lb couch potato. I still really don’t know how it all happened, but it did. I honestly thought my fit days were well behind me and this was it, my life was over as I knew it. Then I met the team at Science Fitness Solutions...
 
This encounter was the gamechanger, and everything changed. No more late-night pizzas and 12 packs. We dropped the bars, bad food habits, the toxic relationship, and went into full cocoon mode.
 
Oddly enough, I now have the same body composition that I had when I was an 18 yr old athlete! Science Fitness Solutions’ training rolled back the clock for me by well over a decade! Most people are shocked to hear I am 35 years old looking this great.
 
Someone asked me the other day if I was taking steroids because these results are truly shocking. The truth is, this process has been all natural. No supplements and no gimmicks. Real food, hard work, and positive affirmation is all that was needed to be my best again.
 
Having the opportunity to learn from Science Fitness Solutions has been invaluable and life altering. This is only the beginning, and I couldn’t have done it without Science Fitness Solutions! They are truly a witness!!"

My fitness journey has been a long one. My highest weight was 275 pounds after losing my parents in a car accident 20 years ago. I went from an athlete to morbidly obese in 2 years.  Emotional eating was the root and not until my doctors hit me with some hard facts did I start to make some lifestyle changes nearly 12 years ago. Slowly over the years the weight came off with a mixture of eating right and exercising. I had several personal trainers over the years but no one that made a great impact. My body adjusted to a stable weight around 180-190 which was a size 12.  I was this weight for years, thought that was the best I could do until I met Mackenzie at Science Fitness Solutions.  I started working out with Science Fitness Solutions in Sept of 2018.  I can tell you…not all trainers are equal. This was different, I knew that from the start. Mackenzie’s approach, attitude and methodology were so different from those I have worked with in the past and so were my results. 
 
He told me to eat! Looking back, I thought this relationship will not last. I am here to lose weight, not gain weight. Ha!  I threw my hands up in the air and said what the heck, this guy is the expert.  Upping my calories paired with hypertrophy training garnered me great results.  I needed to fuel my body. I started to get lean and I was seeing muscles in places I had not seen since college.  This resulted with me getting under 150 pounds and a size 6 which is where I am today.  I get compliments on my arms all the time and the stamina I have to run my company has helped me achieve even greater professional success. 
I am thankful for the results, change in mindset and the coaching.  You will too."
