Revealed: NEW Form of Cardio That Melts Up To 9 Pounds of Fat Every 14 Days With ZERO Equipment
No more long, boring, marathon workouts that fail to deliver the fat burning results you’re after.
Introducing a revolutionary NEW 20 minute cardio training breakthrough that will put an end to marathon workouts – forever!
Plus… Discover the 3 BIG mistakes you’re probably making that stunt your body’s ability to lose fat.
My name is Kate Vidulich and I’m known as New York City’s #1 go-to expert for busy people that want to lose body fat using short, simple workouts that they can do anywhere, anytime.
If you’re over the age of 35 and you’re frustrated with weight gain, a sluggish metabolism, and lack of permanent results, then I’ve got some good news for you…
Today you’re going to discover what just very well may be the single most powerful and effective way to use your body’s own weight to burn up to 500 calories in a single short workout – all while you sculpt a sexy waistline, and kiss your fat rolls goodbye forever.
Yes, that’s an unbelievably huge claim in a market already filled with hype and empty promises, but I’ve been testing this exact method on hundreds of my boot camp clients for months now… and it’s currently delivering results better than anything they’ve ever tried.
So just stick with me a bit longer and I’ll show you the proof in pictures AND I’ll back it up with science…
…because if you’re anything like me then you’re probably a little skeptical as you read this and you want to see the proof, right?
You’ll also learn my secret fat loss formula that solves the 3 most common BIG mistakes found in many of today’s popular fat loss programs.
Frankly, it’s appalling to see these same mistakes made over and over. Not because I don’t expect more from fitness experts (I definitely do), but because of how their negligence confuses innocent people like you who just want to work hard.
You see, many of my clients come to me after having tried unsuccessfully to lose weight. I can tell they’re fed up, embarrassed, and ashamed of how they look. Some have even privately shared with me that when they pick out what to wear in the morning, it isn’t based on what they like best, but what covers them up the most.
I don’t know, maybe you’ve felt that way before, too. I know I have.
Fortunately, in just a minute I’m going to show you how the proven fat loss formula below can immediately accelerate your results—as early as your next workout…
I’ll explain what these letters mean in just a minute, but a few things to know now…
First, everything you’re about to read is based on the latest scientific research, and backed by real results. This means occasionally you’ll come across a number at the end of a sentence. Like this (1). Those are citations of the scientific journals that this amazing fat burning information is based on.
Next, with this formula you will NOT need to train 7 days a week… or six… or even five for that matter. That’s overkill, not to mention it leads to weight GAIN. (2) You’ll discover why 20-minute workouts are the sweet spot to getting fitter, and leaner with no equipment, in just a minute.
Third, with this formula you will NOT need a single piece of equipment – not a pair of dumbbells, not a pull-up bar, not even a stability ball. That easily makes this training method one of the most convenient ways to blast away body fat anywhere, anytime.
The truth is, while each of the principles within this formula is simple, they are also extremely powerful when applied. Once you know how to use it, and by fix those three BIG mistakes, I promise your fat loss efforts will come so much easier and faster.
But before we get to those mistakes, there’s a story I’d like to share with you.
It’s pretty humiliating actually…
Because while for the past 8 years I’ve been fortunate to help thousands of men and women lose weight and reshape their bodies, I wasn’t always the lean and self-assured fat loss expert I am today. I was far from it.
You see, when I was in first year of undergrad at the University of NSW in Sydney, Australia, I took a course called, Sports Science. Most of my classmates had healthy-looking physiques, and I’m sure many of them would’ve said the same about me, too. But that’s only because I wore baggy pants and loose-fitting tops to cover up my fat hiding underneath. In reality, I was 20 pounds overweight and doing everything I could to hide my shame.
That all changed the day our Professor told us to pair up and take one another’s body fat measurements. I went into panic-mode. All I could think about was how everyone would find out just how fat and unattractive I really was.
I wasn’t about to let that happen.
So what did I do?
Well, I seriously considered missing that class, which would have meant failing the course. But I didn’t do that. Truth be told, I’m no better for what I ultimately did do.
Like I said, I’m embarrassed to admit this, but I’m sharing it with you because I want you to know that you’re not alone. I know very well the pain of feeling rejected and undesirable….
So, I purposely chose the largest person in the class to be my partner because I knew my results wouldn’t be as humiliating as hers. I also spent the entire weekend figuring out how to skew my body fat results.
I’m not proud of what I did. But I was afraid everyone would think I was fat and ugly. In the end, however, everyone saw what I’d spent years trying to hide.
But interestingly… this was actually the catalyst for turning my life around. Because it was in those few mortifying moments when I finally realized I had to stop doing cardio if I ever wanted a better body.
Let me ask you this…
Have you ever felt like losing weight, getting lean, and looking great just wasn’t possible for you, and that no matter what you did, you’d still never have a lean body?
I have, and it doesn’t feel very good. But if what I just shared sounds at all familiar, let me assure you it’s not your fault.
You see, the unfortunate reality is that many of today’s popular workouts are not sustainable. They are either too hard, take up too much time, or deliver too few results. Fortunately, the solution is fixing these three BIG mistakes.
The 3 Big Mistakes You Must Fix If You Want To Shrink Your Belly!
Mistake #1: Doing Too Many High Impact Exercises
You probably already know why you should do strength training if fat loss is your goal (it builds muscle which improves your blood sugar, so fewer carbs get stored as fat).
But what about explosive training?
Basically, explosive training helps you develop power, which is how quickly you can exert force to produce movement. For example, it’s power, not just strength that gets you out of a burning building in time, or can prevent you from falling when you start to lose your balance.
Now if done correctly, explosive training can also be used to improve your strength, increase your overall mobility and agility, and boosts your fat burning rate.
Here’s the problem though…
As you age, muscle power fades faster than muscle strength. So adding exercises to increase power becomes especially important later in life. (3) But…
You really have to be careful. Too many programs today do it wrong, which can have disastrous side effects.
You’ll often see Explosive “Jump” training, in many of today’s popular fat loss workouts. And that’s fine… it’s a great way to increase both speed and power.
However, the trouble is the way it’s being used and who is using it.
You see, explosive jump training was originally designed for athletes. But today, more often than not it’s your average Joe using it to get in-shape. And that’s a BIG problem…
Because you should never, ever do explosive jump training before you’ve built up a solid foundation of strength. That means if you are a beginner (or been out of it for a while) it’s best you start with a preparation phase before you doing any type of jumping.
Unfortunately, many programs make you do jump training for an entire workout and puts you dangerously at risk.
Much like strength training, you’ll get the best results from explosive jump training when using exercises suited for your fitness level.
The problem is, most programs list standard “one-size fits all” jumping exercises.
For example, Total Body Extensions are a fantastic explosive exercise for beginners. But more advanced people would burn more calories doing a more difficult exercise, like Jump Squats.
So make sure the workout program you’re using offers progressions and regressions for its exercises. Not only will the workout become more challenging and less discouraging, it’ll also be much safer. And that’s what leads to rapid results.
Mistake #2: Not Keeping Intensity High Enough
When it comes to burning more calories and preserving lean muscle, high intensity exercise is KING.
But you already know that—you read the top fitness websites… you check out the HIT workouts they create… and you see all the research they share. Heck, you’ve probably even heard about the research study I was involved in at the University of NSW. It was published in the prestigious International Journal of Obesity, showing that high intensity training doubled fat burning in half the time, compared to long boring cardio. (4)
However, you may not know that most people are doing it wrong.
Now how can you possibly mess up high intensity workouts, when it’s something as simple as alternating periods of work with periods of rest? Easy….
You want fast results. I get it. But choosing an exercise that you can’t do with correct form for the allotted time eliminates the calorie burning benefits.
So what should you do instead? Choose an easier exercise. By doing this, you’ll keep your intensity high and achieve the desired fat burning effect.
For example, if you’re supposed to do 45 seconds of pushups, but you know that you’ll barely last 20, do an incline push up instead.
How long do you think you could sustain an 8 out of 10 exertion level… with perfect form?
If you said not long, you’d be right. Because it’s REALLY hard.
But that’s high intensity training. And every interval must be performed this way if you want to reap the benefits of the “afterburn” effect. This is when your body continues to burn calories 24-48 hours after you stop working out.
Unfortunately, too many men and women aren’t getting their intensity high enough or resting long enough, and they’re basically doing a glorified steady-state cardio workout…!
Mistake #3: Not Using Progressive Overload
Now, this final workout mistake is THE single most important factor that can stop you from getting results.
You see, the human body doesn’t like change, and is involved in a constant process of adapting to the stress placed upon it. While this has its benefits, if you don’t know how to force your body to change, you will never achieve consistent fat loss.
Let me explain…
When you stress your body in a way it’s not used to (overload), the body reacts by causing physiological changes (adaptation), so it can handle that stress in a better way the next time it occurs.
But to be effective, this stress must be PLANNED. Randomly changing exercises, program-hopping, or using daily workouts you find online will only lead to sub-par improvements, and a plateau.
That’s also why people at the gym performing the same exercises with the same weight/reps every time always look the same, too. They aren’t using progressive overload.
To get amazing abs and build a better body, you need to make your workout more difficult over time. That’s progressive overload – doing more work over time. And the best way to do that is by using a structured proven program built around your goals… and sticking with it long enough to see results.
So there you have it—the three BIG mistakes found in many of today’s fat loss programs, and in all likelihood, the reason for your lackluster results in the past.
But while learning about these mistakes, you also discovered the solution: the ultimate fat loss formula…
Explosive Training + High Intensity + Progressive Overload = Real Fast Results
And since you now know not only what the problem is, but also the solution… you can fix it.
Remember – it’s not your fault you struggled before, but it is your responsibility to fix it now.
So what if I told you there is an even easier way to build an amazing body and burn up to 500 calories a workout? And what if I told you this simple method doesn’t require the use of a single piece of equipment?
You see, if you could do that, you’d be able to crank up your post-workout calorie burn by 450%… and do it just about anywhere, anytime. (5) Can you just imagine how much more fat you’d burn?
Yep, a lot more.
Just imagine how empowering it would feel to finally be in complete control of your weight loss and how adept you would be when you are alive, vibrant, healthy and full of energy… not to mention how good you would look wearing the clothes you’ve always wanted to wear, because now they fit!
And here’s more good news…
There’s actually a super simple, fun, and extremely convenient way to achieve all of that, and even better, it only takes 20 minutes, just four times per week.
I’d like to introduce you to:
Bodyweight Cardio 500 is the first and only workout program that takes just 20 minutes to burn a whopping 500 calories, and doesn’t kill your knees.
In fact, according to the American College of Sports Medicine, a 20-minute workout, four times per week, is the sweet spot for losing weight, building strength, and getting in shape. (6)
That’s why if you’re a busy woman like Rachel Horner, or tired of doing the same boring style of workout like Paul Betz, both clients of mine, you’ll love how short and powerful these workouts are.
“Kate has changed my life in the best way possible.”
“When I first came to Long Island Fit Body Boot Camp, I was 172 pounds and miserable. It was the heaviest I’d ever been and I was very nervous about joining a boot camp as I assumed I’d never be able to keep up. Before working out with Kate, I never really exercised. I’d go through usual cycles of joining a gym, going five times and then never going again.
Kate made working out fun for me, which I thought was an unachievable feat. I lost over 50 pounds, and also gained a confidence I’d never had before. I honestly mean it when I say Kate has changed my life in the best way possible.”
– Rachel Horner, New York, NY
Paul lost 25lbs in 12 weeks and Won $1000!
Before weight: 199lbs
After weight: 174lbs
“I started seeing results and started getting excited. Never had I felt the way I was feeling after being in boot camp for a while. I actually looked forward to exercising!
Instead of spending 45 minutes on the elliptical and even more time on weights bored out of my mind, I’m doing burpees, squats, push ups, plank exercises and more in a circuit that really gets my heart rate up, metabolism working and strengthening my muscles at the same time, all in a short workout! It’s the perfect style of training for a busy New Yorker.
It has completely changed my life. I look better, feel healthier, have way more energy, booming confidence and so much more motivation and courage than before. I’ve accomplished something I didn’t think was possible and now the sky is the limit!”
Paul Betz, 32, New York, NY
This truly is a real, sustainable solution to losing a bunch of weight and keeping it off forever. But more importantly, this training system will transform the way you feel about yourself… like it has with many of my clients, including Jen Theien and Kim Tebbs…
Busy Mom of Two Loses 18.1 Pounds and Gets Back to the Person She Was
“This past January I found myself in a rut. I needed to lose weight and feel better about myself… I started working out with Kate at the Long Island Fit Body Boot Camp, and not only did I find something I loved. I became addicted.
The boot camp workouts were extremely hard and intense in the beginning, but as soon as I started seeing results I kept pushing harder. I was becoming so strong, losing weight and the inches were melting off. I actually looked forward to exercising!!!
As a mom of 2, my life can be pretty hectic. This has been a perfect solution to get me back to the person I was.”
– Jen Theien, New York, NY
“I’m hooked! I don’t ever want to look back”
Before weight: 185lbs
After weight: 166lbs
“It’s true that when you see results you want to keep doing more. Years of treadmills and miles of walking and I never saw the results I see now.
My body fat is going down. I am feeling better. I am sleeping better. Clothes that hang in my closet are starting to fit again. People are saying I look better. I am starting to feel more confident.
I’m motivated now. I don’t ever want to look back. I’m not sure why it took so long to find something that works, but this has. I’m hooked!”
– Kim Tebbs, 47, New York, NY
Now, before I go any further, I should tell you what Bodyweight Cardio 500 is NOTso that you know what to expect…
While other programs may promise you similar results in less than 20 minutes, what you may not realize is how incredibly HARD you would have to work in order to achieve it. With BC 500, you’ll push yourself, no doubt about that… but it won’t seem impossible, nor will it seem so boring you want to quit.
If you’ve ever had to stop working out or take a break from a program because it was hurting your knees, this is NOT that kind of program. In fact, an entire phase of this program is dedicated to preparing your body for safe amounts of jumping exercises.
If you’ve ever invested in a program, thinking you were getting “no equipment” workouts, only to find out later on that you actually needed a pull-up bar, a stability ball, and so on, you’ll be glad to know that with BC 500 you literally need ZERO equipment to rapidly lose fat.
So what can you expect? Simple…
A 30-day, cutting-edge, step-by-step workout plan that offers a huge variety of fun and challenging ways to lose up to 9 pounds of pure fat in 30 days (only 80 minutes per week).

FREQUENTLY ASKED QUESTIONS
Q: I want to start losing fat now. Will I have to wait for you to ship me all this information before I can get started?
A: No! You can download the entire program immediately after your purchase in just minutes – and start using these NEW fat burning techniques today! No shipping fees, no waiting for results!
Q: I’m not in my 20’s or 30’s. Will this program still work for someone considerably older?
A: Yes. We’ve already had plenty of people in their 50’s and 60’s experience massive success while using the program. You can start at the beginner level and still make excellent progress. The program is designed to have you losing fat fast while increasing your metabolism – no matter what age you are. So, simply start with Beginner phase (Bodyweight Cardio 300) and you’ll make excellent progress.
Q: What equipment do I need for these workouts?
A: ZERO. The workouts are designed with bodyweight only, so as long as you have a body, you don’t need anything else.
Q: So how do you KNOW these workouts actually burn up to 500 calories each?
A: Great question. The answer is simple – we tested each workout on an experimental group of more than 10 people. Each person was strapped to Polar Heart Rate monitors with advanced calorie settings, and we measured the read-out.
Q: But how can you claim “500 calories burned per workout” when people of different sizes burn calories at different rates?
A: The workouts were tested on the “average” sized individual. My clients were a mix of men and women, who weighed between 125lbs and 250+lbs.
If you weigh more, you will actually burn MORE calories, while people who weigh less will burn slightly less.
When you include the calories burned post workout in the “afterburn” period, the 500 calorie workouts actually burn WAY more than 500 calories even for people with a lower body weight.
Q: What if I’m a relative beginner, or can’t do high impact exercises? Can I still use this program?
A: Yes! I wanted to make the program suitable for all levels of fitness so you can supercharge your workouts no matter what stage you’re at now.
The program has two levels of difficulty:
Beginner: 300 calorie Accelerator workouts
Intermediate/Advanced: 500 calorie Accelerator workouts
To figure out where you should start, there is a cutting edge assessment workout included in the package.
Q: What if the workouts are too hard?
A: Start conservatively. Take a longer rest between sets or reduce the number of rounds initially. Exercises can always be substituted.
Q: How soon can I expect to see results?
A: Depending where you are with your current training, you should notice results in the first two weeks. Some of my clients have lost 9 pounds in the first two weeks. By the end of your first month, you’ll have noticeable changes.
Q: What if it doesn’t work for me?
A: Then it’s 100% FREE.
Just drop me a line some time before 60 days, and I’ll issue you a no-questions asked refund. I stand behind this program, and truly believe it is the most effective no-equipment training system to deliver fast, real results.
If doesn’t yield those results for you when followed, you get your money back. No hassles, no hoops to jump through, just a prompt, courteous refund.
