I’ll reveal my specific 'outside of the gym' formula that helped me quickly becoming the 2019 Champion at the CrossFit Games.

†Results vary depending on starting point, goals and effort. 

My Story

I was 38 when it all came together for me.

I was overweight. Tired all the time. No energy, no life.

Feeling like I was going to end up like everyone else in my obese family.

“Maybe it’s just in my genes,” I thought.

I had given up.

But not without a fight!

In my early 30s, I tried running consistently.

I ran an hour a day, every day.

But it turns out I couldn’t outrun my “eat what I want” lifestyle.

Had I just spent an average of 14-minutes per day on better workouts (more on that below…)

I’d have gotten the results, the energy, and the LIFE I wanted.

Maybe you can relate to what my life looked like:

7am: Every morning I’d have a big old bowl of cereal and maybe some toast for good measure.

10am: STARVING -- so for lunch I’d have pasta or leftover pizza or a big old sandwich with chips. Oh, and let’s not forget - cookies after lunch!

2-3pm: My one healthy habit - take a run. This was actually the highlight of my day.

4pm: STARVING again. I’d reach for the chips or pretzels.

5pm: The beers start rolling, 2-3 by the end of the night. More if a game was on and the neighbors were out and about.

6pm: Dinner. Pasta with a baguette.

9pm: A bowl or two of ice cream.

Then I’d wake up STARVING the next morning, and repeat it all over again.

In-between every meal, my energy was up for a minute…

Then I would crash…

Overall, I just had no energy for anything.

I was only 38 -- but I felt OLD.



That was a low point for me.

Then I looked at my 3 month old child… My third child, in fact.
And it hit me:

“I’m a new dad again. I need to be around and HEALTHY for another 20-30 years. Not only that, I have to be FUNCTIONAL and ACTIVE. I have to do SOMETHING.”

Something I’d never done - find something that really works.



I realized I could literally rewrite my future!



  • From a waist size of 36” to a 31”.
  • From a jacket size 38 to a 42 - I added muscle.
  • From a lack of energy to an excess of energy.
  • From STARVING to SATIATED - often having to remind myself to eat a meal.

My workouts became what I now call
“Short-Burst, Rapid-Burn Workouts”

During my transformation, each of my workouts were ONLY 7-20 minutes! Averaging around 14 minutes of serious sweat!

Yet they’re SO MUCH MORE EFFECTIVE than anything else.

Remember: I used to run an hour a day!

I pack even more calorie-burning, muscle-building, body-slimming action into an average of 14-minutes. And some of my workouts are as short as 7 minutes (hint - the shorter the workout, the more challenging the workout actually!)

90-minutes per week replaced 7+ hours, and my results SKYROCKETED.

And yes -- that is ONCE PER DAY! So with a total of an average of 14-minutes per day, and eating the right foods (which are DELICIOUS by the way!).


My results were great from the start - but I knew what I was eating was still holding me back.

I ate so much food… and such bad foods… that every step I took forward, I also took a step back.

So I dove into nutrition research.

My goal was simple: Uncover an eating lifestyle that was EASY and DELICIOUS.

Food is very IMPORTANT to me. I need to ENJOY it.

A diet that took the joy out of eating - NO THANKS. I’d rather just not get fit!

I discovered something extremely simple -

If I was consistent in my workouts…

I could eat nearly ALL of the protein and fat I wanted…

I just needed to keep an eye on my carbs.

Don’t worry — I didn’t CUT OUT carbs altogether! I just kept them ‘under control’ with foods that I loved.

Toast and cereal were replaced with roasted broccoli, sweet potatoes and eggs.

I throw butter in my coffee - because it’s delicious among other things (I can teach you all about it).

Afternoon snack: A handful of nuts (salted and yummy).

Dinner: Grilled chicken with olive oil, all the garlic, and salt. Roasted brussel sprouts. And a solid scoop of rice or a stuffed potato.


I’m never starving. I’m never on this rollercoaster of “OMG I NEED TO EAT!”

I have to REMIND myself to eat sometimes!

I LOVE everything I’m eating.

In fact, I enjoy food now more than ever.

I’m EXCITED for EVERY MEAL because it’s both delicious, and helping me stay fit and energized.

I love it.

Small successes are the building blocks of bigger wins.

Scientists aren’t sure exactly why, but small changes often have a ripple effect.

Changing a couple of habits has ended up changing my life!

I’ve shared these ‘secrets’ and helped 1,000+ men & women over the years. Here’s what a few had to say:

"I’ve been to the gym plenty... but at 64 years old, I feel better than I have in decades and I look 10 years younger. I’m happy, strong, and able to do whatever I want to do."

Bob C.
Age: 65

"We wanted to change our lifestyle and be healthier. Once we started, we were hooked. We want to bring up our daughter in a healthy home and teach her healthy habits and work ethic. We both did sports in high school and college but struggled to find something as adults until we discovered this. It just fits! We also love being sore everyday 😜"

Erica & Justin
Age: 33

"As hard as it is to get up some mornings, I have never left the gym regretting getting up and going. Exercising is something that I have done off and on over the years but never really stuck with it. Nothing I have ever done has been harder or more rewarding than this. I am getting to the age where sticking with Jason has made me feel over all more healthy."

Berk W.
Age: 55

"It’s made my life better in more ways than could ever be explained. The day I met with Jason to talk about joining I was a very unhealthy 260 pound 30 year old. I’ve become much healthier and am in the best shape I’ve ever been in, and there’s lots of room to improve. I had old injuries from years of playing football that I thought were just a part of my life forever. Through working on mobility and building strength I no longer hurt and the old injuries no longer haunt me everyday."

Donnie B.
Age: 34

"The workouts, the nutrition guidance, and the community have helped me to meet my weight loss goals and build strength and muscle. Never had muscle definition in my arms before...kinda like it!"

Patti D.
Age: 56

The Science Behind Rapid Results

It’s simple: INTENSITY beats EVERYTHING.

My short workouts are more powerful, more effective, more muscle-toning, more metabolism-boosting than a 60-minute run on the treadmill!

Because these workouts up the intensity safely… we can reduce the time.

But that’s not all:

The workouts combine BOTH Aerobic and Anaerobic exercises into one.

Aerobic exercises increase heart strength and stamina. Anaerobic exercises build lean muscle mass and boost metabolism.

By combining both -- into short, intense periods -- we get results. FAST.

Workout at home. Or at the gym. I give you both options - always!

At home -- A set of dumbbells and a jump rope. Can’t afford a dumbbell? Use a couple of milk jugs!

At the gym -- simple equipment, no machines.


And we 5x our results with a simple, easy-to-follow Nutrition Blueprint.
