Hits everything and it’s fun! Tony, 54

PowerJump Training has changed my body more than anything I’ve ever done. I lost 10 pounds in the first month, and firmed up every muscle. It’s fun, easy to travel with, and makes me feel 20 years younger.

Felicia Soares, 50+


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!

“I’m Totally Addicted To PowerJump.
There Is No Better Full Body Workout"

~Jake, 42.

CATALYZER. Jumping Rope outside, like jogging around the park
The 20 minute PowerJump workouts are super fun, give me tons of energy, and keep me strong for tennis, running, and skiing. In every workout I can jump, tone my legs, hit my upper body and core, even with my 2 kids around.

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 PowerJump Training 2-3x/week my back is a lot stronger, less stiff, and I’m able to enjoy Jiu Jitsu and Dirt-Bikng with my teenage son. I’ve also gotten a lot leaner and gained muscle mass.
Dan Young, 58, General Contractor (Young Construction) 
STRONG guy using a short anchor at the door and, using the catalyzer for boxing with resistance.
With PowerJump, losing 12 lbs in 3 weeks was easy because I can go really hard, and not get hurt. Plus it’s fun! I’ve done lots of different workouts over the years and nothing hits every aspect of my fitness so hard, and so well. It’s worth every penny and the online workouts are awesome!!!

No! Well…Yes, because technically Every Body Is An Athlete in Progress! Over the past 2 years we’ve trained exercisers/athletes of all ages (5-84 years old), and all abilities, and learned that CrossJump Training is for Every Body if you know how to “scale”/modify each exercise to make it work for you. In the Free CrossJump Fundamentals Instructional video, we’ll show you exactly how to make each exercise easier or harder, so you can create the perfect adaptation stimulus for YOUR Body. We’ll always try to meet you where you’re at, not where we’re at… 

The short answer is all women should start on RED, and all men under 6’1″ should start on black. A big guy taller than 6’1” should opt for the longer “heavier” gray cord.

So here’s the long answer…The 3 colors are slightly different lengths, and different tension levels to accommodate different heights and “strength” capacities.

The beautiful thing about our elastic PowerCords is they elongate to 3.5x their original length so there’s a LOT of different tension levels from beginning to end of max-elongation.

Naty (my wife) and Carmen (our friend in the videos/images) are 5’2 and 5’4” respectively and VERY strong. They prefer to do every exercise with the Red PC although they always have access to black. Dan (in the videos & garage) and I are ~5’10”, 165 lbs and we use the Black PC for every exercise we do. When we want to go light we minimize the elongation. For harder sets, we’ll put the cord under more elongation/tension and can get all the “heavy” loading we want. So if you want to double your resistance you simply use 2 PC’s simultaneously. And for the big, tall guys out there, you won’t be disappointed by the Gray PC. We’ve got a handful of 6’5” 300+ lb guys we work with who get all the workout they need from the Gray.

Shoot us an email at support@coreenginefitnes.com if this doesn’t answer all your questions!

Not much…

Roughly 6’ x 12’ will get the job done for all of the exercises.

But if you don’t have that much room, there are still hundreds of different exercises that can be done in half that space.

No. You’ll have anytime/lifetime access to dozens of CrossJump FUNdamental exercises with the CATALYZER.

There are hundreds of different ways to arrange the exercises shown in the one hour Instructional Video, so you can design your own workouts—for free– for the rest of you life if you want to.

We’ll also have lots of 20 minute workouts available to purchase separately if you’re looking to constantly keep it fresh and effective.  

Monotony is the enemy of progress when it comes to getting results from training. The tricky part, and where most well intentioned exercisers err, is creating variety at the expense of effectiveness and safety.
We’re happy to leverage our 60 years in the trenches as full-time Trainers, to constantly vary the exercises and workouts so you’re always getting better, without getting hurt.
So if you’re looking to evolve beyond the Fundamental exercises and free workout, we’ve got an endless supply of CrossJump workouts waiting in the wings to take you to higher levels of Fitness. 
Start with the kit that best suits your budget and goals. Think of this as a long-term investment in the quality of your Life. And know that you can always add additional components later. 
We’ve learned that when it comes to purchasing athletic equipment, it’s not worth it for us to start with anything less than the highest level…Because we know that in the long run, we always want the best so we don’t feel limited by our gear. So we would rather “stretch” a little in the beginning and start with the highest level package (bike/skis/shoes/CAT), versus starting with the entry level package.
Whatever CAT kit you decide is best for you right now, just know that we’ll be there every step of the way to insure you get the results you deserve from every workout!
Just send it back within 30 days, and you’ll get a full refund.
Of course we’d like to hear from you well before you’re dissatisfied to see if we can help you work through whatever issues your having, BUT, if it’s just not for you we’ll refund your money. We’re in this to make our customers happier and improve quality of life, so the last thing we want is an unhappy customer. Always feel free to reach out (Bill@CoreEngineFitness.com) with any questions or issues, so we can try to work through whatever challenges you’re facing.
