WHY DOES YOUR CARDIO GAS OUT MID-WOD?

It’s not about effort, it’s about using the wrong approach. Most athletes train hard but never build a true multi-energy system engine.

NORMAL WODS AREN’T ENOUGH

Most daily WODs last just 8–15 minutes, too short to build the deep aerobic base you need to power through intense workouts. You need targeted “Engine Time” sessions.

JUST DOING MORE DOESN’T WORK

Adding random runs, rows, or extra miles won’t move the needle. Without structured progressions, you risk overtraining or spinning your wheels with little improvement. You need “Precise Progressions”.

GENERIC CARDIO PLANS DON’T FIT CROSSFIT ATHLETES

Most cardio programs are built for endurance-only athletes like runners or triathletes, not for people balancing heavy lifts and gymnastics. You need “Functional Cardio”.

IT’S TIME TO BUILD YOUR ENDLESS ENGINE!

First, you need to understand something:

Gassing out during workouts isn’t a sign you’re unfit, it’s a sign your cardio system isn’t trained for the demands of CrossFit®-style training.

 

You need a proven system that pinpoints your weak links, builds efficiency, and boosts endurance, all while letting you keep lifting heavy and hitting skills.

Instead of logging random miles or hoping your next WOD magically builds your engine, you need structured sessions designed to increase your aerobic capacity and recover faster between reps.

 

Good news, you don’t have to guess anymore …

 

WODprep is proud to introduce Endless Engine, the only multi-energy-system cardio program built for CrossFit® athletes.

 

Best of all: Endless Engine is included inside WODprep Academy, along with the full course library, online programming, and coaching support.

The results speak for themselves!

Meet your instructor,

Ben Dziwulski

Over the last several years I’ve been a box owner, trainer, regional-level athlete, and perhaps my favorite – a full time online coach.

My coaching tactics have been featured in BOXROX, Tabata Times, WodNews, RX Magazine, The WOD Life, and WOD Nation to name a few. As you’ll find out, I like to teach in a crystal-clear, easy-to-understand way. Most importantly, I like RESULTS.

 

So if you’re trying to finally “Rx” this difficult movement, I’ve got you covered!

 

So far, hundreds of athletes have made DRASTIC improvements using this exact training system.

 

Not sure if this is right for you? Check out the FAQ’s. You make the call.

 

And make sure you read about my unconditional money back guarantee. I want you to join the Rx division without any hesitations, and I’m willing to put everything on the line to make sure you are successful!

Thousands of athletes trust WODprep. The results speak for themselves!

18.1 – 282 reps – all TTB unbroken (last year I had to break up 4-4). Never would have done that last year! Thank you WODprep coaches and TTB Transformed!

Justin / Verified Customer

I just wrapped up the course last week. Within the last 2 weeks, things have really clicked when it comes to stringing my TTB together. The biggest thing for me has been lat engagement – that really helped me to stay consistent throughout workout

Angelo / Verified Customer

I just wanted to say – we had strict toes to bar in the workout today and I did 8 unbroken, 24 total! I couldn’t even do one of these 2 weeks ago!

Kim / Verified Customer

Love your Open Prep videos. I am a Master’s Male Rx athlete in the 40-44 age group. This is my 5th year competing in the Open. 
I have been following your tips for the last 2 years.

David / Verified Customer

Good day today! We did Annie for part of our WOD, and it was the first time I was able to do it Rx. Got all of the DU’s unbroken!

Bill / Verified Customer

After all the advice and tips earlier in the week from WODprep, 
I was able to complete 17.2 with 12 BMU’s! Thank you!

Jay / Verified Customer

Our guarantee to you!

Our guarantee to you! If you don’t LOVE this training program, 
I insist that you get 100% of your money back.

Let me tell you why … I invite you to use WODprep Academy for a few weeks and measure your progress (which we’ll do inside the program). All I ask is that you watch the results. I’m confident you’ll be impressed.

 

I built these courses over YEARS; pulling from both the self-learning AND coaching aspects of bar muscle ups. Using things that I’ve taught myself, and things that I’ve used to teach hundreds of athletes just like you.

 

I’ve thrown out all the things that didn’t work, which leaves everything that actually works, and THAT is what’ you’ll find on the inside of WODprep Academy. These courses aren’t just about becoming an RX athlete, it’s about knocking down the biggest obstacle that stands in your way on the road to becoming a better athlete.

 

It’s about simple coaching, my life’s work. And if I can help you permanently join the Rx division…or compete…or help you beat a few of your workout buddies in the next WOD…I consider it a job well done.

 

So here’s my simple offer: If you don’t LOVE this training program, I insist that you get 100% of your money back. It’s simple: Join the program and see for yourself.

Got Questions? We've Got You

How do I start Endless Engine?
You’ll gain access to the course, by purchasing WODprep Academy directly on the WODprep website using our secure payment platform. You’ll receive WODprep Academy as long as you’re a member and have access to the video library, rehab protocols, daily programming, educational courses plus WODprep coaching via our online training platform.
Endless Engine is a comprehensive 12-week aerobic capacity course designed to teach you the science of pacing and engine building. Unlike a standard monthly track, this is an educational deep dive that combines workouts with lessons on breathing, lactic clearance, and strategy.
Yes. The course platform is fully mobile-friendly. You can stream the video lectures and view your daily training assignments from your phone while you are sitting on the rower or heading out for a run.
Setup is instant. You receive your login details via email immediately after purchase. You can watch the “Welcome” module and start your first baseline test right away.
The course is versatile. You can complete it using a Rowing Machine (Concept2 preferred), an Air Bike (Assault or Echo), or simply Running shoes. We provide specific tracks for each modality.
Yes. The course begins with an introduction to the “Engine Hierarchy” and explains how to read the programming prescriptions (like RPE and Negative Splits) so you train effectively.
This is a complete 12-week system, but your purchase includes lifetime updates. If we add new pacing strategies, bonus modules, or updated drills in the future, you get them for free automatically.
Yes. If you have a cardio machine at home or a place to run outside, this is the perfect program to follow on your own schedule without needing a full gym setup.
No. The course is hosted on our web platform, so you just need a web browser. However, you can download the training PDFs if you prefer to have a hard copy to track your splits.
Yes. We walk you through the philosophy of “Stop the Redline”—teaching you why most athletes train cardio wrong and how this course will fix it.
Who is Endless Engine designed for?
It is for the athlete who “gases out” early in workouts. If you start fast but die in the second round, or if you feel like your lungs are the limiting factor in every WOD, this course solves that problem.
Yes. The sessions are designed to be supplementary. You can do them as extra conditioning work 2-3 times per week without interfering with your strength training or class workouts.
Yes. The programming is based on your current fitness level. We use RPE (Rate of Perceived Exertion) and relative pacing, so the intensity scales perfectly whether you are a novice or an elite athlete.
Whether you want to crush a 5k run, improve your 2k row time, or just survive “Murph,” the physiological adaptations (increased anaerobic threshold and recovery) apply to all endurance goals.
WPx Engine is an ongoing monthly subscription with weekly workouts. Endless Engine is a structured 12-week course (one-time purchase) that includes heavy educational content to teach you how to pace for the rest of your life.
Yes. The physiology of aerobic conditioning is the same for everyone. The pacing strategies and interval structures work equally well for men and women.
Yes. We include specific technique modules for Rowing and Biking. Often, athletes aren’t unfit; they are just inefficient. We fix your mechanics so you stop wasting energy with every stroke.
This is a one-time purchase, so you own it forever. There is no need to switch; you can simply return to the course whenever you feel your conditioning slipping.
The program is designed as a 12-week progressive cycle. We strongly recommend following the weeks in order, as the volume and intensity build systematically to peak your engine.
We do not offer a free trial for single courses, but we do offer a 60-day money-back guarantee. If you do the work and don’t see an improvement in your capacity, we will refund you.
How often should I train?
The course prescribes 2-3 dedicated engine sessions per week. These are focused intervals designed to target specific energy systems (aerobic, anaerobic, lactic).
Most athletes see a massive improvement in their ability to sustain work. You will learn to hold a pace that feels “uncomfortable but sustainable” for much longer, and your recovery time between intervals will drop drastically.
Yes. We include detailed breakdown videos for running mechanics and rowing technique. If you are a WODprep Academy member, you can also upload videos for coach analysis.
You track your progress by completing benchmark tests at the beginning and end of the 12-week cycle. You will also track your interval splits daily to ensure you are hitting the right stimulus.
Yes. We explain the intent of every workout via video. We also include drills for breathing mechanics and movement efficiency.
Yes. A bigger aerobic engine recovers faster. By improving your cardiovascular efficiency, you will clear fatigue faster during rest periods in a WOD and recover faster between training days.
Just pick up where you left off. Aerobic adaptations are long-term. Do not try to double up on sessions to catch up; just resume the plan and trust the process.
Yes. We start with aerobic base building and technique, then move into threshold training, and finally high-intensity lactic power intervals to peak your performance.
Yes. You can connect with other athletes in the course comments or the main WODprep community group to discuss pacing strategies and share your benchmark times.
You will see a mix of “Map 10” (aerobic base), “Map 1-3” (anaerobic power), and “Lactic Tolerance” intervals. We also include specific breathing drills and pacing tests to ensure you aren’t just sweating, but adapting. Can I get help with my form? Yes. We include detailed breakdown videos for running mechanics and rowing technique. If you are a WODprep Academy member, you can also upload videos for coach analysis.
What’s the cost of Endless Engine?
Individual courses are found inside WODprep Academy, which starts at $59 per month!
No. It is a one-time purchase. You pay once and keep the course forever. You can repeat the 12-week cycle as many times as you want.
Yes. We offer a 60-day money-back guarantee. If you put in the work and don’t feel fitter or faster, we will refund your money no questions asked.
There is nothing to cancel since there are no recurring fees.
We sometimes bundle this course with “WODprep Academy” or offer it at a discount during specific launch windows like the Open season.
No need. You have lifetime access, so you can take a break for injury or life events and come back whenever you are ready.
You get the full 12-week training plan (customizable for Run, Row, or Bike), the “Pacing Strategy” seminars, breathing protocols, and technique workshops.
Yes. If you struggle with the self-paced format, you can hire a WODprep 1-on-1 coach to write a custom engine program for you tailored to your specific schedule.
Yes. You can earn commissions by referring friends via our Ambassador program.
N/A for one-time purchases.
How to improve CrossFit cardio?
Endless Engine focuses on raising your Anaerobic Threshold. By training your body to clear lactate efficiently at higher intensities, you can move faster for longer without “blowing up.”
We teach the concept of Negative Splits. This means starting slightly slower than you think you should and speeding up as the workout goes on. This is scientifically proven to produce better scores than the “fly and die” method.
Redlining happens when you exceed your threshold too early. We teach you how to find your specific “Redline Pace” so you can stay just below it, maximizing your output without crashing.
Yes. We teach specific breathing gears (Nasal vs. Mouth). Learning to breathe rhythmically helps regulate your heart rate and keeps your nervous system calm under stress.
It is usually poor technique or a low damper setting. We teach you how to use your legs (not your arms) to drive the machine and how to set the drag factor correctly for your size.
Yes. We have a specific “Running” track within the course. We focus on cadence and foot strike to make you a more efficient runner, which translates directly to Murph and other running WODs.
It is your body’s ability to flush out the “burning” sensation (lactate/hydrogen ions) from your muscles. We use interval training with specific rest ratios to train this system so you can recover faster mid-workout.
No. While we do some base work, the program includes high-intensity intervals, sprints, and threshold pieces. It is designed for the demands of functional fitness, not marathon running.
Cardio adapts relatively quickly. You will likely feel a difference in your breathing and recovery within 3-4 weeks. Significant performance PRs usually happen by the end of the 12-week block.
Absolutely. Engine workouts require you to sit in the “pain cave.” Learning to hold a pace when your body wants to quit builds the exact mental resilience needed for competitive CrossFit.
