Define Your Muscles By combining the 3 Drivers of Muscle Hypertrophy/tone, with the 3 Drivers that maximize Fat-Burning, we’ve created the perfect recipe for building lean, powerful muscles that make your body harder to kill, and easier to enjoy in Life & Sports.

1. MAXIMIZE MUSCLE DEFINITION

By simultaneously overloading the 3 Drivers of Muscle-Tone, the CAT is the ultimate tool for building lean & powerful muscles.

Coordination Every repetition of every exercise should be an opportunity to improve balance, athleticism, and kinesthetic intelligence. Having “strength” without coordination is a lot like having a Lamborghini without a steering wheel…

2. DEVELOP COORDINATION/BALANCE

The CAT is uniquely designed to improve balance, athleticism, & kinesthetic intelligence in every rep, of every exercise.

Figure8's with the CATALYZER. Best for Mobility!

3. IMPROVE MOBILITY/ELIMINATE BACK PAIN

Overloading 3-D movements with the CAT improves functional mobility, reduces muscle/joint stiffness, and resolves back pain.

FITNESS ISN’T ONE THING; IT’S 6. 

WE CALL IT THE 6-PACK OF FITNESS

Stamina By building stamina in every muscle fiber, we maximize the number & size of the mitochondrial fat-burning factories which make it easy to get lean and stay lean.

4. SKYROCKET STAMINA/FAT-BURNING

Aerobically challenging nearly every muscle fiber, in every exercise, maximizes the size and number of the mitochondrial fat-burning factories, making it easier to get lean, and stay lean year-round.

STRENGTH Training: We engineered the CAT to safely and effectively overload dozens of 3-D movements that mimic the loading demands of Life & Sports. There’s no need to ever touch a dumbbell/kettlebell/barbell again.

5. BUILD FULL-BODY STRENGTH

99% of the “strength” we need in Life passes the C.A.T. test: Uses the Core as an engine for rotational power. Alternates ground-force from one leg to the other. Requires the brain to Think about coordination/balance. 99% of the full-body movements we train pass the C.A.T. test!

Core Engine Rotation Half of your body’s total muscle mass is designed to rotate your hips, spine, and shoulders. We overload your Core Engine in every exercise so you can get ripped and powerful. 

6. GET A RIPPED POWERFUL CORE

Your Core Engine™ is 50% of your total muscle-mass designed to burn fat, and produce powerful rotational forces. The CAT is the only training tool that overloads your Core Engine™ in every rep, of every exercise, creating a ripped powerful mid-section. 
5/5
When I was training weights, I knew I should be doing separate cardio, mobility and core work but didn’t have the time. It wasn’t until after kids that I started having major back issues from having a weak and tight core.
 
Since I started training with the Catalyzer, my body feels SO MUCH BETTER. I can go super hard, get EVERYTHING I need from one workout, and not feel completely wrecked the next day.
 
It’s helped my lower back, pelvic floor, and the best part is, I can do it all in my living room with my kids!

Certified CrossFit Trainer

What I love most about my Cat is it doesn’t ever hurt me, changes my body quickly, and it’s super FUN 🙂 When I return from a long busy trip, I know I can lose 10 lbs and whip my body into shape in just two weeks!

Felicia Soares, 50+

Brandon

When I hit 40 and retired from 12 years as a Pro Cyclist, I decided to change my body and sport. Training with the Catalyzer improved my balance and core strength, added muscle mass and power, and got me on the podium in several XC Ski Races. I highly recommend it!

Brandon Lynch, 42.

Want to know the biggest secret to getting Leaner, Stronger, Better???

A secret that took us 60 years combined– as trainers and pro-athletes—to discover….

Want to know the biggest secret to getting Leaner/Stronger/Better???

A secret that took us 60 years combined– as trainers and pro-athletes—to discover….

It’s called the Core Engine™: 

It’s 50% of your total muscle mass and you’re not training it properly.

It’s designed by Evolution to be the primary power source for every 3-D movement in Life & Sports.

It’s the most effective way to get out of back pain, and back to performance.

It’s got half of your mitochondrial fat-burning factories that aren’t being used.

Nobody trains it effectively, because nobody understands it.

Watch Core Engine Training in action!!!

BILL USING THE SHREDDERS FOR Flexibility&CoreStability: Every movement we perform in Life and Sports necessitates dynamic—not static—flexibility; and dynamic—not static—“stability.” We’ve created dozens of loaded movements that simultaneously improve mobility, and the Core Engine’s ability to produce, transfer, and manage/stabilize movements…not planks!
Play Video

The CATALYZER™ is the only training tool specifically designed to overload the Core Engine in every repetition, of every exercise.

Here’s how Core Engine™ Training changes your body:
Core Muscles trained with the CATALYZER
BURN MORE FAT &
BUILD LEAN MUSCLE
Incorporating rotation into every exercise skyrockets the size & number of mitochondrial fat-burning factories, making it easier to get ripped, and stay lean year-round.
More Core Muscles trained with the CATALYZER
IMPROVE MOBILITY &
ELIMINATE BACK PAIN

Full-Body rotational movements–at variable speeds and loads– are the best medicine for stiff joints/muscles, and eliminating lower back & neck pain.

and more Core Muscles trained with the CATALYZER
BUILD POWER &
PERFORM BETTER
Overloading the rotational muscles—50% of total muscle mass—in every exercise maximizes muscle-density and full-body power production for every sport. 
5/5
“The Core Engine is real, and it turned out to be a huge untapped source of power for me. Knowing how to train it, and use it properly has been a game changer for my running, cycling, and nordic skiing.

I have no doubt my Core Engine is what powered me onto the 2019 Birkie podium after a 7 year draught, very little training, and just 2 days after getting rear-ended by a snowplow and suffering a nasty concussion.”
 
~Matt Liebsch, World Cup Skier, Birkebiener Winner 
Play Video
I herniated the L4/L5 disc in my lower-back from overdoing weights and tennis in 2011. I did rehab and TRX, but nothing made my back feel better and stronger than all of the rotational Core work in the PowerCAT Training.
 
 Aside from losing fat and toning everything—including my legs!!!—I’m cycling, nordic skiing, and playing tennis better than ever.

Probably from working construction for 40 years, my lower back has always been a weak link. Until I started using the Catalyzer, I was so stiff I could barely walk in the morning. 
 
Now after 8 months of PowerCAT Training 2-3x/week my back is a lot stronger, less stiff, and I’m able to enjoy Jiu Jitsu, and Dirt-Biking with my teenage son. I’ve also gotten leaner and gained 6-7 lbs of muscle.

If you’re like most exercisers, you’ve already spent over $4,000 on 300 pounds of functional-training equipment. How much better is 5 lbs of CATALYZER at a small fraction of that cost???

5/5

“I feel bad for buying a gym full of equipment that’s just taking up space, when the only thing I use is the CAT. But there’s just no comparison in terms of fun and results. With the CAT, a 1 hour workout flies by because my brain is challenged, and my entire body is on fire. Worth every penny, and the online training is awesome!!! Cole, 48

Judy

When we discovered the Catalyzer, we were thrilled to find a full-body workout that not only boosted our energy, strengthened and toned our muscles, and helped increase our endurance, but best of all, we finally have a training routine we can do together!

Judy Cahill, 62.

From a medical standpoint, the CATALYZER checks all the boxes for safety, effectiveness, and whole body overloading that mirrors the variable demands of our lives and recreational activities. There is no better training tool for athletes looking to improve upon any of the myriad facets of functional fitness.

Adriane with the catalyzer

“I never even knew I had a Core Engine until I worked with Bill. After only 3 weeks of training with the Catalyzer my body visibly changed—I had muscles!—I felt so much better, and my skating was stronger: more solid, supple, and powerful at the same time. 

~Adrienne Carhart, Figure Skating National Champion  

Macky Trainig to be part of the gold rower team
“Failing to earn a spot on the travel team—as a Collegiate rower—was devastating. I went to Sun Valley for Xmas break and after only 2 weeks of Core Engine training with the Catalyzer, my mood was better and my body changed.  A leaner and stronger version of me returned to College, beat my best Erg times, and got selected for the Spring Travel Team!” Mackay Johnson
