The Quad Blaster is a unique, hand-made, one of a kind portable machine. There’s nothing like it in the whole world! When I couldn’t do squats, I used it as an integral part of my training that took my thighs to championship caliber when I claimed the Natural for Life World Bodybuilding Champion title in 1985. Because of my back condition I could not do barbell squats but needed a way to stimulate maximum muscle growth for my legs. Read my full story to find out how this invention was discovered and developed. I have used The Quad Blaster myself for 34 years and this was one of my secret weapons that I used to train my “H.I.T. Squad” of bodybuilders to become champions in their own right. My personal clients have also benefited from its use at my private practice for many years. I am now making this amazing machine available to the public for the first time! It’s safe, sturdy, the most intense way to work your thighs, and it will last a lifetime. Anyone who wants to develop and strengthen their thighs can benefit from The Quad Blaster, even if you don’t have back problems!

Quad Blaster Testimonials
Natural Bodybuilder and world-renowned author,
Tom Venuto Speaks About the Quad Blaster
Normally, I don’t ascribe any “special powers” to ANY single piece of equipment. In my view, every piece of equipment is just a tool and nothing replaces the basics like good old barbell squats. But then again, “the basics” were the reason the Quad Blaster was invented… what about the folks who want to do the basics, like barbell back squats, but cant because of lower back problems?
Well, necessity is the mother of invention, and that’s how and why the Quad Blaster was invented. You see, Carlos had suffered from severe low back pain, which prevented him from doing ANY barbell back squats, but as a competitive bodybuilder, he knew that leg extensions weren’t going to cut it.
Instead of trying to figure out what exercise could replace squats, Carlos asked himself how he could do squats without pain. It was actually by accident how he got the idea. One day, he was standing in front of a railing that was about mid calf in height. The heels of his shoes got caught on the sidewalk edge just beneath the railing and locked his feet into place.
At that moment, there was a group of people passing by, so he leaned back and squatted down to get out of the way and he immediately felt his front thigh muscles kick in and he noticed there was no back pain. He did it again, this time deliberately. “WOW!” he said to himself, “If I could only get this kind of effect in the gym!” So, that’s exactly what he set out to do and the quad blaster was born. The year was 1974. By 1979, Carlos had the plans copyrighted, and then in 2000, he had the device patented. With a little help from his own invention, Carlos achieved great success in bodybuilding and became one of the pioneers in drug free bodybuilding, winning the 1981 Natural Mr. USA, the 1981 Natural Mr. North America and the 1985 Professional Natural Mr. World Carlos DeJesus for Posing.
If you look at the photos and illustrations, you will notice two distinct characteristics of the quad blaster squat:
First is the narrow stance. In fact, the feet are completely together. This foot position is almost not possible with a barbell squat, as great flexibility is required for narrow stance barbell squats. The narrow stance squat, as many bodybuilders realize, is a highly quad dominant exercise. The wider stance decreases the isolation of the quads. This foot position makes the quad blaster an ideal bodybuilding exercise.
The second thing you’ll notice is the vertical torso. On a regular barbell squat, the torso inclines forward. This is a normal position, required to maintain your center of gravity (otherwise you would fall over). On a smith machine, you can squat with a vertical torso, but the quad blaster is a very different effect.
As for resistance, most people will struggle with just their body weight the first time out. A 40-50 pound dumbbell is pretty good resistance even for strong squatters, if the proper form is observed. The dumbbell can be held on the front of the shoulders, much like a front squat (which is my preference). The alternative is to hold the weight behind you as in a barbell hack squat.
Some people who looked at the quad blaster the first time said, “Its nothing special, it’s just a roman chair squat.”
Indeed, the roman chair squat is about the closest thing there is to the quad blaster, but mark my words, it is NOT the same thing. They ARE similar, but you have to use the quad blaster to appreciate the uniqueness of the device.
Like a roman chair squat, it does NOT take much weight to get a killer “quad blast” with this device, especially when form is perfect.
Perfect form on the quad blaster means that you keep a vertical torso or even a very slight lean backwards. As you incline your trunk forward, stress comes off the quads and the hips, glutes and low back take some of the load. It is much more difficult and effective with a vertical torso.
Perfect form on the quad blaster also means (to me at least), continuous tension, non locking reps. If you stand up completely, then all the stress comes off the quads. If you perform 3/4 to 4/5 range reps, this keeps tension on the quads through the entire rep and the entire set.
This is the most intense workout for the thighs. Don’t be deceived by the simplicity of this machine. Once you’ve tried it, nothing can compare with it.
You don’t need to put heavy-duty weights on your back. Because of the beauty of design, The Quad Blaster generates immense difficulty through leverage so that holding a 10-pound dumbbell translates to 200 pounds to your thighs. This will save your back and knees. It’s so well designed that even put through the worst of trails by a World Champion; even he couldn’t damage or break it, even with years of use.
Because the total weight is about 15 pounds The Quad Blaster is easily portable and perfect for travel. The side handle makes it easy to pick up and go. Most will especially appreciate this feature. Not exactly what you can do with a bulky machine!
The Quad Blaster is compact enough that it fits in the back seat of your car, in the trunk, or under your bed
Priced so that everyone can afford one. There are three ways you can get one. Pick the one that is right for you so you can jump-start your leg training by having your very own Quad Blaster.
An isolated-integrated exercise
“Single joint isolation exercises aren’t a great use of time for athletes or for most people. But the ability to emphasize a muscle group using an “isolated-integrated” exercise is extremely valuable.
The Quad Blaster is a fantastic tool for doing just that. You can really target the quads in a squat pattern without loading the spine, lower back or joints. It’s been a great addition to our programs at Results Fitness.”
Helped me capture the 1992 World Championships!
“My name is Kathy Brady. I have used this amazing Quad Blaster and it is in a class of it’s own. Being a woman sometimes it is a little harder to get definition in your legs –well this state of the art piece of equipment gave me cuts and definition in my legs that no other machine could touch. It helped me capture the 1992 World Championships.
I highly recommend this product.
Carlos– thank you so much for sharing this with me. It gave me the edge I needed on the competition!!”
1992 Women's World Champion
It creates amazing growth!
“I started to use the Quad Blaster about 8 weeks ago and I have been amazed at what a wonderful quad workout I get from it. In those 8 weeks my quads have grown 1.25 inches and my actual squat weight has gone up 75 lbs. I incorporate the Quad Blaster into every leg workout and it totally does what it says–blasts my quads. It is safer than a squat as it doesn’t force you to hold heavy weight on your back and shoulders. I personally believe that if you have back problems, foot problems or any other structural issue that causes you to avoid squats, the Quad Blaster is the device for you!”
