It's Time To Take Your Strength AND Physique to the 
Next Level With This Kettlebell Program

"What's the best way to train with kettlebells?"

I've spent the last 10 years of my career exploring this very question.

Whether you want to be as strong and jacked as possible, or just look, move, and feel better, some methods have just proven themselves again and again.

Now, after thousands of hours in the gym while working with hundreds of students from all walks of life, I've come to rely on a rock-solid formula to maximize the potential of any athlete.

It's The Power of Synergy...

I'll be honest - I'm a programming nerd.

Experimenting with exercise combinations, techniques, volume schemes, and cycles is a real passion.

A good workout program is like a good recipe: The right mix and sequence of ingredients makes all the difference.

When everything comes together just right, there's a magic, or synergy, that creates a result greater than the mere sum of parts.

And that's exactly what I'm offering in my new training course - Kettlebell Synergy.

Here's what you'll find inside:

Phase I:
Build Endurance and "KettleBooty" With
Classic Swing Interval Training

There is no shortcut for rapid improvements in both physique and performance.

But the kettlebell swing sure comes close.

As a coach, I've found an influx of swings can take care of my students' most pressing issues. 

Stubborn body fat melts off, strength numbers jump up, and you just feel taller and better aligned.

Phase II:
Skyrocket Strength and Muscle Gains With The Dynamic Duo of Kettlebell Front Squats and Military Presses

For decades, savvy lifters, athletes, and bodybuilders have employed high-repetition squat sets to trigger the "hormonal cascade" that boosts muscle hypertrophy and fat loss.

In particular, the double kettlebell front squat is well known for fortifying the body from head-to-toe. "Armor Building," as strength coach Dan John would say.

The military press offers us a master class in strength training.

Mechanically, the press is one of the most challenging lifts to master.  And therein lies its secret as an all-time strength and muscle builder.

When you dedicate your efforts to the military press, you'll sculpt a classically muscular upper body with mobility to match.

Taken together, the dynamic duo of kettlebell presses and squats will slap a huge helping of functional muscle on your frame, all while developing super strong and resilient hips and shoulders.

Phase III:
Put Your Strength To The Test With A Collection of My Favorite Hard-Hitting Kettlebell Complexes, Chains, and Strategic Supersets

The kettlebell is the most versatile tool we have in our fitness toolbox.

In the final phase of Kettlebell Synergy, we break away from a strict programming scheme and introduce fun new workouts to challenge your skills with intelligently-designed variety.  

Additionally, you'll finish each workout with a muscle-swelling pump courtesy of some old-school  isolation work. 

The result will not only solidify your hard-won strength gains, but put the "finishing touch" on your fat loss and muscle building efforts.

Included:
A No-Nonsense Nutrition Course
To Maximize Your Results

From a training standpoint, you can make great strides in your performance by by simply following the workouts...

But to maximize your physique results in the cutting of body fat and building of lean muscle, we must be as diligent and focused in the kitchen as we are in the gym.

I'm not going to needlessly overcomplicate things, nor am I going to suggest any sort of strict diet.

Quite simply, I'm going to walk you through a flexible and proven method that, when paired with the KBS workouts, will produce rapid results.

Here's What Folks Are Saying About Kettlebell Synergy


James lost 19 pounds and got in the best shape of his life (at 51 years old)...

"I'm really happy with the results.  Pressed a 70 lb for 3 on my right and 2 on my left.  I've never pressed this bell before in my life.

Down from 216 to 197 lbs from doing your program.

I'm definitely in the best shape of my life."

- James from Iowa


"Kettlebell Synergy is the definition of simple, yet effective programming that will take your physique, strength, and skills to the next level.  Not only does Zack teach you HOW to master the kettlebell swing (among other movements), he teaches you how to program all these lifts into your weekly routine for superior results.

And that's not all.  Zack went a step beyond writing a training plan and included a very detailed, user-friendly nutrition guide to boot!  This guide offers advice and strategies for getting the best physique results when paired with his training program.

As a kettlebell coach myself, I've seen a lot of programs out there that just skim the surface and leave the student with more questions than answers.  

Whether you're new to the kettlebell or an elite lifter, this program is for you.

Frankly, Zack is charging far too little for this course (sorry to call you out, man).  The price is worth the nutrition guide alone.  Get this ASAP before he gets smart and ups the price!"

- Nikki Veit, SFGII, SFL, Co-founder of 901 Kettlebell Club


Eric's shoulder strength went through the roof!


"The thing I love most about KB Synergy is how you take the basic movements and make them more advanced simply by the structure of the program.  

Many "advanced" programs these days are just needlessly complex flows.

This is the type of program I know will get me stronger, while allowing me to continue to hone my techniques in the tried-and-true lifts.  I am so excited to incorporate this into my own training!"

- Tracy Cook, SFGII, SFL, USA Powerlifting national champion

Frequently asked questions

How many kettlebells do I need?

You won't need a massive kettlebell collection to get the most out of KBS.  

Just 3-4 bells will get it done.  

Ideally, you'll have a pair of bells for squats and a weight you'd like to set a military press PR (personal record) with.  The manual details exactly what bells to use in each phase.

What makes Kettlebell Synergy different?

KB Synergy is the complete package for enjoying improved performance and aesthetics with kettlebells.

Many programs lack smart and sustainable progression from week to week and month to month, yielding lackluster and inconsistent results. 

Kettlebell Synergy builds up and off of itself every step of the way.

What if I'm a total newbie?

 I suggest picking up my first flagship kettlebell training course:     Kettlebell Foundations. 

Run that program first, and you'll be ready for KB Synergy in no time.

Will I get jacked?

The periodization model is designed to help you cut body fat, build muscle, and maximize your strength.

Work hard and you'll come out in your best shape ever.

What if I'm an advanced kettlebeller?

Many so-called advanced programs these days are just needlessly complex flows.
