Get to Know Jason Grubb (2019 Crossfit Champion)

Learn the secrets to transforming your body and life from out-of-shape to championship athlete - Jason Grubb.
2019 Crossfit Champion, Busy Dad and Online Trainer.


I was 38 when it all came together.


Tired all the time.

No energy, no life.

Feeling like I was going to end up like everyone else in my family: struggling with obesity and low energy.

"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.

And it turns out, had I just invested in an online personal trainer (more on that below…) — I’d have gotten the results, the energy, and the LIFE I wanted.


Jason Grubb transformed his life from out-of-shape and overweight to Crossfit Champion as a busy working parent. 

I ate carbs with a side of more carbs… Can you relate? (It’s okay! This is a judgment-free zone!)

Sugary, carby cereal! Oh, and with toast!


STARVING! Can barely think! Hello PIZZA! And COOKIES for dessert!

(Just 3 hours later I was starving... These days? Hunger is non-existent!)


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

(1 full hour per day - now I get BETTER RESULTS - in much less time!)


STARVING again. I’d reach for the chips and pretzels.

(When you’re starving all the time… it’s hard to make good eating decisions…)


The beers start rolling – 2-3 by the end of the night. More if a game was on and the neighbors came over.



A bowl or two of ice cream.

Sugar! AKA CARBS!!/p>

After every meal, my energy was up for a minute… then would crash…

Overall, I just had no energy for anything.


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 HEALTHY for my family.

I need to be FUNCTIONAL and ACTIVE.

I need to change.

That desire was stronger than the taste of pasta, ice cream, and beer.

I hit the drawing board. I desperately sought a way out of my energy-draining, unhealthy life.


That’s when I stumbled upon what I now call “Short-Burst, Rapid-Burn Workouts.”

All of my workouts are only short, simple, and effective (and no more than 30-40 minutes, with some under 14 minutes!) —

They are SO MUCH MORE EFFECTIVE than anything else.

Remember: I used to run an hour a day!!

Now, I pack even more calorie-burning, muscle-building, body-slimming action into short full body workouts.

And yes – that is ONCE PER DAY! So with just 1 workout per day, and eating the right foods (which are DELICIOUS by the way!) — I changed my life.


My goal was simple: Uncover a healthy eating and fitness lifestyle that was DELICIOUS and SUSTAINABLE.

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

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

I discovered something extremely, extremely simple — If I know exactly what to eat, and when to eat it... I don’t feel limited!

Eating whole 'real food' made me more satiated and full than all the carbs I could ever eat in my previous life.

I'm never starving. Ever. And I often have to set a reminder to eat.

And don’t get me wrong — I still eat carbs… I just eat healthy carbs that fuel my life and make me feel great.
