The Best Kept Secret in Fitness
Ok, first i say to get this out of the way, no I'm not paid, padded, prodded, or patted to give my thoughts on the Bullworker in this case the Steel Bow. When I was a young boy, we are talking like quite awhile back. I had an opportunity to have one of these. It had such a carry over effect, that it stayed with me throughout high school, out into football, weightlifting the whole thing. People under estimates these little gems. I get so tickled, that's why they can say, "The Best Kept Secret In Fitness". Why? My dear friend. Sure for more than 20 years or better hospitals, and such incorporate isometrics into Rehabilitation, because it's fast and effective to get one quickly onto the road to recovery. Please don't think it is not effective because of it's lightweight...think again. Look at a little of its History. Bruce Lee used a Bullworker during a point in his career. Muhammad Ali I believe help to promote it. Isometric exercise was used in space missions, because besides weights taking up a lot of space (no pun intended) there was the issue of no gravity, so what use would weights be. Then there is Alexander Zass, best known as the Father of Isometric workouts. He was a strongman who bent steel, carried a mid size horse over his back, and many more incredible stunts, was he known for a lot of weightlifting, not much, matter of fact he came to develop his own isometric workout. Back to the Bullworker. It's secret lies in the fact that it's easy on the joints, can tone, define, build strength, and make you Stronger and Quicker without hurting yourself. All that is even needed is only 60-70% of your strength for gains. But today they have all kinds of different exercises with the Bullworker Program. They usually come with a wallchart, and or heavy duty carrying case. Not to mention you can get different accesories to add on, and they help extend to even more exercise and variety. As of now they have the " Bow Classic" Bullworker about 36" has 2 springs 0-50 and 50+ ..the Classic has etched in levels with a ring as well as the other that lets you know how much you are doing..good for 6'0 and above, now it says that it reads 260 at max, all I know is, once there was being offered $20 bills at a Arnold Schwarzenegger Classic if anybody could compress and this was the older models probably not as strong, but nevertheless I believe it were only 4 out of like a hundred or so that could do it, it was discovered they all benched over 400 lbs. and The "Steel Bow" Bullworker 20" good for under 6'0. But that is even not written in stone, a lot of guys and gals prefers the smaller one of is equally as strong. It comes as of date with 3 springs the reading doesn't go as high, but I would not want to try and use the third spring to try a ten second max. Really a person has to try one to believe it. They are like anything, you can't like just look at it and say it works. They are fast and easy to use, no downtime, no changing weights, machines...and like only 7 seconds per exercise and you are done! You can literally do a 5 minute smooth routine and like bam, done! Matter of fact they often would say this, look into the mirror today, then look again in two weeks you will already start seeing results. Most first time users are amazed with the very first workout because of the way it feels in their muscles. Not only that but the Bullworker will build tendon strength, I believe that may be part of its Secret..but my advice read what others say especially on like a Bullworker Site, or like on a face book ...there are guys who have had these since like for 20, 30 years, and some of them have actually used them for 30, 40 years...even weightlifting people who wound up with busted up joints comes around and uses them..All I can say is you got to actually experience one first hand. These are the REAL DEAL no knock-offs, you buy it, they will last most people 20-30 years or even a Lifetime. Many guys had one for like 20-30 years, then pass it down to their children, friend, next of kin...It's almost like a Secret Club or hidden thing, but once you've in or get involved you're There. Hope this helps.

Everything it says it is and more!
I gave my first Bullworker (purchased in 1973!!) to my son a few years ago, and occasionally wished I had it back. I recently realized that I was becoming less and less able to perform some physical activities. so I decided to purchase another. After watching several videos and reading reviews, I settled on the Steel Bow Classic model as it seemed to be more applicable to what I wanted to do. I also did exhaustive research on isometric exercise. I had come to believe some of the negative press on Isometrics, but came to learn that almost all the negative research on isometrics was either flawed or simply non-existent. Latest serious research, however, is unanimous; isometric exercise is the most effective exercise for beginners, those at an intermediate-level of fitness and seniors who are looking for something simple and fast that will help them dramatically improve their fitness level. Fact is, isometric exercise, when used with proper breathing techniques, has been found to reduce blood-pressure while increasing strength, cardio-vascular health and overall fitness levels almost twice as fast as isotonic and aerobic exercise while greatly reducing stress on bones, joints and tendons. Isometrics also makes it easier to maintain a level of fitness once attained. From there, the decision to actually purchase the Steel Bow was easy. I received the equipment on the date promised and was extremely pleased with what I found when I opened the box. The Steel Bow absolutely oozes quality. Over the years I have owned several different pieces of exercise equipment, some costing 20 times more that the Steel Bow, and none of those products showed the level of fit and finish shown by the Bullworker. The Bullworker I gave to my son is now 46 years old and going strong; it's easy to see that this Steel Bow is built to a higher standard of production and assembly. I was off to a good start. Attention to detail is evident in every aspect of the equipment. There are two additional, higher resistance springs included, there is a spiral bound, heavy card-stock, glossy book with dozens of exercises orgainzed by the area, a likewise high-quality wall chart for easy reference while doing a workout, and a super high quality case has a special pocket for the different springs. There is even a non-slip rubber pad to prevent slippage when an exercise calls for resting one of the handles on the floor or on one's knee. As for the exercises? Well, I have only just begun, but after the FIRST DAY of running through some of the basic exercises that I remember from years ago, I am confident that anyone who tries the Steel Bowl and uses it AS DIRECTED will notice exactly what I noticed; an almost immediate sense of increased strength and power. I'm on my third day now, and I can tell you that it is no illusion. The Steel Bow by Bullworker is specifically designed for isometrics, and isometrics is probably the single best mode of exercise for most everyone who will do it as per directed. P.S. It is important to note, isometric exercises typically consist of one to three compression or extension exercises that are then HELD STATIC for a period of 7 to 10 seconds. After years of lifting weights and doing calisthenics, it is hard to believe, without actually trying it, that isometric exercise as described can have a GREATER impact on your strength and fitness than either weights or calisthenics, but it can and WILL, if you commit to the program. Yours, for better health!! Michael Schmidtman

Excellent device for isometric exercise
First this is a sturdy well made product. I already follow an effective full body workout and have done so for almost 60 years. I purchased this to maintain strength on trips, but haven't made any trips since the purchase. However, I have been using it for isometric exercise after my usual routines. The original isometric idea was based around pulling as hard as possible against an immovable force and in the early research of which I am aware they were looking at emulating the Olympic lifts, at that time there were three. Because of this many muscles throughout the body were involved at one time causing a large increase in blood pressure during the lift. The Bullworker does not involve more than a few muscles at a time so there should be no concern about blood pressure. I have found that exercises in my usual routine feel easier after a couple of weeks of the isometric addition. I think this works better than pulling against a stationary object because the spring creates a tension that the muscles must overcome to maintain position. Pulling against a stationary object sometimes results in unknowingly reducing tension. So this is an excellent device for isometric isolation movements. Because it has a limited range of motion you have to do many exercises to work the muscles through a full range. Because of this I will keep using my isotonic routines and use the Steel Bow as a strength supplement. I imagine this could be effective even with the limited range of motion for someone who does not follow another type of routine. I use weights, callisthenics and a couple of simple machines.

Having had an original bill worker I decided to buy a new steelbow this is a great quality product, there are plenty of workout routines on the bullworker YouTube channel to follow. I would highly recommend this product .

I have owned an original Bullworker for about 50 years and it's still functioning properly. It is portable, but I was looking for something even more compact and versatile, and saw the Steel Bow with interchangeable springs on Amazon. This new device is greatly improved with more comfortable grips and handles on the cables. The gauge is now on the tube instead of a plastic strip that could break off. The biggest improvement is the quickly interchangeable springs. These let you start at an easier level and work up to a very difficult push, pull, or lift with the heaviest spring. Mine came with a nice carrying bag and a spiral bound book with a 90 day transformation program. I started the 90 day challenge on January 1st, 2020 and as of today, March 4, 2020 I have lost 3 pounds of fat, my waist has shrunk, and yet my arm muscles are bigger and much better defined. There are some great exercises for all parts of the body and my legs are stronger and my six pack is now showing again. My goal is to get stronger and leaner which should help me be faster in my Masters Middle Distance races. The 90 Challenge and the great support from the Bullworker team and the community of users has really increased my motivation to use this device to its fullest capability. No exercise device will work if you don't use it properly and consistently. This device, and the people behind it, will get you started and keep you going on a very effective fitness path.

Bestes Trainingsgerät, welches ich jemals gekauft hab. Für den Preis absolut fair. Ersetzt zig anderen teure und große Geräte. Einfach ein Allrounder für alle Muskeln. Trainiere jetzt schon paar Wochen mit und macht einen robusten Eindruck und man kann leise trainieren. Kleine Verbesserung hätte ich noch, was jetzt aber nichts mit dem Gerät zu tun hat. Ein kleines Fach zum einstecken des Übungs-Trainingsheftes wäre toll.

Un aparato muy interesante.Bien construido, compacto y de buena calidad.Sería perfecto, si trajera más de tres resistencias . El salto entre resistencias me parece excesivo, sobre todo entre la segunda y la tercera.

Produit reçu beaucoup plus rapidement que prévu initialement. Possesseur d'un Bullworker X5 depuis... plus de 35 ans, je connaissait ce type de produit. Ce qui m'a poussé à en acheter un deuxième (et en taille plus réduite) - car le miens est toujours comme neuf - c'est la taille de l'appareil pour certains exercices et sa facilité à être emporté partout. Le plus c'est le fait qu'il y ait trois ressorts, donc résistance réglable selon son niveau ou l'exercice. Donc je dis très très très très .... très bon et beau produit. Bien fini, respire la qualité, bref un vrai Bullworker. Je recommande les yeux fermés. Livré conforme à sa description avec les trois ressorts, un rond de caoutchouc, un livret, une magnifique housse de transport...
