Review: 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 . Review: 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 desertcart. 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. ## Features - Designed to perfection - Compact construction - Easy to maintain - It comes in a safe and secure packaging ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LQKABM | | Archery Draw Length | 51 Centimeters | | Archery Draw Weight | 58.97 Kilograms | | Best Sellers Rank | #94,543 in Sporting Goods ( See Top 100 in Sporting Goods ) #810 in Strength Training Grip Strengtheners | | Brand Name | Bullworker | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (703) | | EU Spare Part Availability Duration | 5 Years | | Global Trade Identification Number | 00896529000016 | | Hand Orientation | Ambidextrous | | Item Weight | 1 Kilograms | | Manufacturer | Bullworker | | Material Type | Aluminum | | Model Name | Steel Bow | | UPC | 896529000016 | ## Product Details - **Brand:** Bullworker - **Colour:** Black - **Item weight:** 1 Kilograms - **Material:** Aluminum - **Model name:** Steel Bow ## Images ![Bullworker Portable Steel Bow - 20in - Image 1](https://m.media-amazon.com/images/I/71kAdwYh6sL.jpg) ## Questions & Answers **Q: will this beef up my forearms? also, how is it for waist and leg workouts?** A: Yes, to forearms. Also, yes to abdominals (waist). Somewhat short for leg workouts, but workable. You will have a full description of all exercises. The best solution is to buy the Steel Bow and the Bow Classic for variety and optimum range of motion. **Q: Why doesn't Amazon sell this on Prime? i can buy it for $85 free ship on Bullworker site?** A: Where do you see it for $85? **Q: How much weight resistance is the spring that is already inside of it?** A: I don't know the exact weight resistance of the spring initially in it but it is VERY soft. Pumping or squeezing and holding this spring is more of an aerobic exercise - expect to be able to do 100 or more. It comes with 2 additional springs that are very easy to change - no tools required. My biggest complaint with the unit is that the progression between springs is extreme. The first one is probably fine since it would be good for weak children and people well into their 70's and 80's. The next level up is quite stiff and resistive requiring some degree of strength. The final spring feels like a steel bar to this 60 year old! **Q: whats the circular rubber pad that comes with the set used for?** A: exercises that work on your abs, lats, and obliques have you sit on a chair, place one end of the instrument on the chair at various places (between your legs, on the outside of your thigh, etc) and compress the spring with both hands while the steelbow is slightly angled. The rubber pad is used on the table or chair to both protect the surface of the chair (in my case I use a very sturdy coffee table) and to help prevent the handle on the chair or table from slipping. I hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***N on 30 August 2024* 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.

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. ## Frequently Bought Together - Bullworker Isometric Exercise Equipment - Steel Bow 20", Portable at Home Gym Equipment for Back, Shoulder, Chest, Biceps, Triceps, Abs, Arm Workout, All in One Exerciser for Men & Women, 0-130lbs - Bullworker X5 Pro 28" - Isometric Exercise Equipment, Strength Training Portable at Home Gym Equipment for Back, Shoulder, Biceps, Triceps, Abs, Chest and Arms, Home Workout Exerciser for Men & Women - Iso-Bow Pro by Bullworker | The Isometric Pocket-Companion for Strength Training, Stretching, and Working Out.
