The Steel-Bow is the ideal product for anyone serious about improving their fitness. The included and revolutionary 30-minute Sit-at-Home Fitness® routine gives you an exercise for your whole body while sitting in a chair. You choose what works for you, 5 different fitness disciplines (Isometric / Isotonic / Resiliency / Endurance / Iso-Motion®). The Steel-Bow allows you to mix and match fitness programs you will never outgrow.

  1. Stewart Laing

    This is a serious piece of equipment. Im 54 and have muscular definition better than when I was in my 20’s. You can take it anywhere and the quick change springs help you to challenge different muscle groups.

  2. Sandeep Suryavanshi

    This is the one of the finest total body fitness equipment out there. I don’t have extra time for gym so in search of an alternative I found Bullworker and since then it has become my best friend. Bullworker products are awesome and there is no doubt it will benefit anyone who invest in Bullworker products.

  3. Utah Fanootch (verified owner)

    I’ve been using my Steel Bow for about a year and a half now and I love it. It’s very versatile and with so many workout routines and options, your workouts never get stagnant.

  4. Duane Gray (verified owner)

    It has been almost five years since I first bought a Bullworker Classic. In my opinion I don’t look any different but I sure do feel a lot better. And my strength has improved at least 75%. I was very weak from surgeries and injuries.
    However in the long run I would not trade-in any of my Bullworker products for anything because I have grown to love and trust these products to deliver the results I am looking for. And now that I have increased my strength, I am now focused on toning my body as much as I can.
    Besides the Bullworker Classic, I also have a Bullworker Steel Bow; one Iso Bow; and a host of exercises that came with the product and Bullworker Challenges that will keep me busy for some time while I conquer my goals.
    Thank you both senior and junior Mr. Hughes’

  5. Chrisman Hughes (verified owner)

    As the president, and a big believer, I use Bullworker products regularly. I love my Steel Bow as a versatile, stand alone total body muscle targeting device. Specializing in isometrics and the best Bullworker for ISO-MOTION.

    I tend to interchange my Bow Classic and Steel Bow during my workouts with my Steel Bow being preferred for chest compressions, curls, ISO-MOTION exercises, and hip adductions.

  6. Nadim T

    Absolutely LOVE the steel bow. Smaller than the bow classic, but better for travel – this baby goes with me on all international trips. Especially when I don’t have access to a full gym, I really like taking this out and getting a 15-30 min workout in before a work dinner. I’ve even used it at the lounge in an airport #noshame, pretty sure people were jealous because I could work out at the airport and they couldn’t!

  7. Steve Gambhir

    I have been using the Steel Bow for a while. I also have the Classic 36 inch one. They both work will in targeting different muscle group.
    What I like is that I can do this while watching TV or even at the office where I have another pair.

    The customer support is fantastic. Chrisman answered my inquiries promptly!

    Their manual is well laid out and easy to follow!

  8. Richard Gaudet (verified owner)

    Excellent product. I call it « my own little gym » I always bring it with me, with some straps when I travel or go camping. Very versatile piece of equipment. Can be use on vertical, horizontal or oblique plan and I consider them more useful than weights which use only the vertical plan (gravity). It’s a must for senior people who can easily hurt themselves with weights. The Steel Bow , like it’s big brother the Classic Bullworker, is very safe to use.

  9. Grant Hoffman (verified owner)

    I did weights for about 30 years but after a cycling trip away became frustrated that I could not take them with me. So I decided to start looking at alternatives, that were a bit gentler on my body. I did two 30 minutes training sessions a day with weights so I just switched to using the bullworker instead. Every 4 weeks I go to a Physio/manipulator to keep my posture correct. I started with the bullworker 3 weeks before I saw him. I did not tell him that I had changed from Weights. He started prodding my back and then said “whatever you are doing you must be doing something different, as you have really muscled up.” I repeat that I did not tell him, he discovered it by feeling my back and arms.
    In short, I totally believe in this product.

      Wow, what an incredible testimony to your efforts! Powerful! Thank you for sharing and best of luck with continued growth!

    I bought my first bullworker in 1975 and it helped me grow to one of the strongest students in my high school. I recently acquired a steel now and am now 60. Within a few weeks of using it I felt strength returning which in turn helped to increase my testosterone levels that my doctor took note of. Now my 14 year old son has been watching me and when I told him of my history and benefits I enjoyed he wanted to give it a try. I showed him the exercise routine and the rest of the book is being written now. It is safe to say that we are now a multi generation bullworker with no thoughts of looking back. It helped me recover from major back surgery from a workplace accident. It played the biggest key role in my recovery. The steel now is without question the best piece of exercise equipment I have ever owned! It works superbly is good for all ages, holds up exceptionally to rigorous heavy use and I can not say enough about the steel now and Bullworker. Great product! Outstanding customer service! A product and equipment that is simply the best I have ever used.

      Love that generational wisdom and good solid work to stay fit! That is wonderful you had such a great recovery thank you for sharing and your kind words!

    Hi Folks,

    like many people I am in quarantine for the Covid-19 and the best system for being fit is the Bullworker. I have long and short models of Bullworker. It’s excellent for a good training of all muscles moreover in this period in which we cannot go outside for the sport. It’s the best option. I am 62 and very proud to be fit like I am.

  12. Herman Lawrence

    My bullworker is helping me get back in shape after having surgery. I am very thankful for this great pice of kit.

  13. Herman Lawrence

    A great piece of equipment.

  14. Kory D. (verified owner)

    The Bullworker Steel Bow is a solid piece of equipment. I have a job that requires a fair amount of travel. I have long had a home gym and frankly have no desire to go to a commercial gym. While it is not practical to bring weights with me when I travel, the Bullworker Steel Box fits right in my luggage. A fast and intense workout is available to me anytime with just a few feet of floor space. The Bullworker Steel Box is solidly built and contains enough varied resistance springs in the package to provide even the strongest person with a good, solid workout. Try one! You won’t be disappointed!

      Thank you for sharing your story. What a fantastic application and challenge you solve with your Steel Bow!

    I have owned by BW for 8 years. It is made of quality stuff. I have used it four times a week. BW is really good at keeping informed of new workouts and items they have for sale.

  16. Kevin Loncar

    The steel bow is ideal for many exercises that require a smaller unit. Much nicer than the older versions.

  17. D.A. Bell (verified owner)

    The Steel Bow and the Classic Bow are the two finest pieces of physical fitness equipment I’ve ever used. These two ingenious devices come from a noble lineage going back a half century. Along with the Steel and Classic Bows, I do exercises with my Japanese X-5, another classic from the distinguished Bullworker line. The current Bullworkers are unparalleled in their superb build quality.

    • Chrisman Hughes (verified owner)

      Thank you for sharing, 3 very powerful products! Huge smiles to hear!

  18. Ronald Ferris

    The finest fitness unit I have found. It is great and it WORKS, assuming that you do.

  19. Barry Stallard (verified owner)

    This is a great piece of equipment. I owned one many years ago when I was in High School and loved it then. Now the new and improved unit(s) are are even better. Unlimited exercises and instructional material that help you to get the most from the unit.

  20. Ed

    I’ve worked out for 45 or more years now. A friend introduced me to the BullWorker in the 1980’s. I was absolutely delighted to have seen your advertising two years or so ago and without hesitation purchased the BullWorker Bow Classic, Steel Bow, IsoBow and accessories. I can personally testify that the BullWorker Bow Classic, Steel Bow, IsoBow and accessories are truly remarkable products and strongly recommended them to supplement any athlete’s or home enthusiast’s fitness program.
    Thank you for these incredible products!

    I purchased one of the original Bullworker series in the 1970s. I did not use this extensively then. I moved from Canada to New Zealand and left this behind. For decades I used free weights. I then purchased the Bullworker X5 about ten years ago. I clever design with the nylon straps that allowed you to increase the range of movement and tension by selecting the straps. This still did not allow for adjustment on compression of the springs. The X-5 was supplemental to the weights but did not use it much.

    Years ago, I had to abandon dead lifts and squats due to arthritis changes in my back. When where and how bad you develop arthritic degenerative changes is a genetic trait that will eventually develop in most people when the get older. I am now 68 yrs old. I still use free weights combined with a Swiss ball, but the Bullworker X-5 was in the closet.

    I then saw that that newer models now had five interchangeable springs and came in a compact version. I did more research on the benefits of isometric training. Yes, you can get stronger, but only within the limited angle of the contraction. The weights allowed for tension in a wider range of movement. I thought that with the steel bow, and the interchangeable springs I could adjust the tension for individual exercises in the same way that you adjust weights. Changing springs would allow for tension on a fuller range of movements and angles. Newer publications by Marlon Birch outlined a program showing the exercises and step up workouts to push the muscles into metabolic failure.

    I ordered the Steel Bow as this would supplement the X-5. I found that the exercises would work out more varied muscle groups than was possible with weights alone. There were even leg workouts that were not possible with weights. I still do squats with dumbbells and Swiss Ball for Quads, and Swiss ball alone for hamstrings. My workouts are now 70% Bullworker and 30% weights, and the combination is better than weights alone. I do 50 minutes and 30 minutes alternate days and one rest day a week. I have done this now for 6 weeks, and I can tell the gains. At 68 I feel I can continue this regime for years, and a way that weights alone cannot.

    After checking some journals or high intensity interval training, doing his 23 minutes once a week is almost as effective as three times a week, so I could probably back of the number of sessions without loosing results.

    One of the disabilities of getting older is getting weaker, a condition called sarcopenia. This can certainly be slowed down with proper strength training and nutrition. Researching several journals also shows strength training improves cognitive executive function of the brain (even in mice).

    There is less chance of injury with the Bullworker with the caveat not to push to 100% tension (easy to do) or you will overstress your tendons. This is always mentioned in the instructions. When done correctly you do a get real workout.

    I purchased my first Bullworker in 1977. I used it on a non regular basis for 2 or 3 years but I FIRMLY believed in the principle behind it. Due to all the things going on in my early 20,s I lost track of my Bullworker. Fastforward 40 years. I rediscovered the new Bullworker Classic and the Steel Bow. I am now 64 years and spent the last two months kicking ass 3 plus times a week. It is very enjoyable using the tools to build myself up to a point I haven’t been to in many years! Just remember vary your routine occasionally to, as Arnold said, keep your muscles guessing! I feel great! Happy workouts!

    Started using the Bullworker in the mid 1960’s to tone up for Gymnastics and have used it one and off for these many years. I recently got the Bow and at age 70 it is ideal, I am building muscle and now in better shape after heart surgery. Bullworker is a great fitness tool.

  24. Larry Matwee

    Started with the Classic Bow 48 years ago and have been using the Steel Bow for the past 4 years. Now in my 70s I find the Steel Bow easier to use and it gives me better results. As an added bonus , it’s compact size has encouraged my wife to start using it. The workouts give us additional strength ,good muscle definition and a strong core. We take the Steel Bow when we travel to maintain our daily workouts. The customer service and support from Chrisman has been greatly appreciated.

  25. Josh

    Purchased a steel bow because for certain exercises were a bit hard and figured a shorter model would help with that. It definitely did. Great construction and the new improved handles are a game changer. Very happy with my purchase and recommend to people who want a way to exercise at home.

  26. Jim Sheffield (verified owner)

    I’m a record holding powerlifter and have included the bullworker in my training for over 30 years. I’ve found that it is great not only for building muscle but for building stabilizing strength for my benchpress. I was able to compete at an elite status well into my 50’s and attribute much of that success and longevity to my years of training with the Bullworker. I highly recommend getting one.

  27. David Litwack (verified owner)

    Great all purpose piece of exercise equipment. Functions as a mini-gym. I actually find I get a better workout with this than I did when I was working with weights in the gym. Quite economical when you consider the cost of dumb bells and barbells these days. Lent one to my son, but he wouldn’t give it back to me. So, I had to buy another. Well worth it.

  28. George Jones (verified owner)

    I first had a Bullworker in my thirties. Now, at 77, I have another one! An excellent piece of kit for general fitness as well as muscel development. Used every other day as instructed, it helps keep fit in a big way. Due to the current situation, I can no longer get to the gym twicw a week and this is more than a substitute.

    My only disappointment was on being asked to pay a customs surcharge by the carrier when it arrived. No doubt it tells me about that in the small print, but who reads small print. Be up front about that Bullworker!

  29. Brer Rabbit (verified owner)

    ….Purchased my first Bullworker in 1974 if my memory serves me right. Purchased second one maybe ten plus years ago which I gave to my son. The present Bullworker was purchased a month ago….. No issues than, None now….Good Product!!

  30. Chris Bowman

    I have been using Steel Bow for over 6 months, it’s great and very effective on it’s own and or in conjunction with other exercise routines that include Bullworker Classic and or Iso Flo. Highly recommended.

  31. Brandon Keuchkerian

    I started with chest expanders with 5 loose strings & then I found a Bullworker imitation from a nearby pharmacy. I used those two for several years but I was never fully happy with the results . . . And then by accident I saw a video of the Bullworker on YouTube, and I realized I was looking at a perfect exercise machine ! I now have the 20″ Steel Bow and I know that this is the best that can be !
    It is a masterpiece of creation for physical wellness & the perfect muscle machine !

  32. Bryan Taphouse

    I’ve had a bullworker for over 50 years ! After being diagnosed with cancer almost 4 years ago my fitness and weight suffered with all the treatments and I didn’t exercise much because of fatigue etc. In January I decided to get a Steel Bow as it’s more portable. I started the 90 day programme in early Feb and did 3 sets of each exercise. The result is that in the 90 days my fitness and shape returned and I have lost most of the cancer weight gain. After the original bullworker in 1966 eventually tired I got an X5 and am now using this with the Steel Bow. The support and advice online is great too.! This is a brilliant product and there can be nothing better for home fitness. I highly recommend Bullworker.

  33. Rajendar Menen

    I have been using the Bullworker for over five decades. We were introduced to them as kids. In the years that followed, I have traveled and worked in different continents and I had to part with the Bullworker several times. It never breaks. So I gifted three pieces to friends. Now I am in one place, thanks largely to the virus doing the rounds, and I have a new piece which is also spectacular. I have been doing yoga and isometrics for decades. I am still very strong and fit. Tight, taut muscles, not bulging ones. But lethal, compressed power. Like a lithe panther. Even those double my size cannot arm wrestle me.

    The Bullworker is a fantastic piece of equipment. I also have the Iso Bow. Ordered online. I live in India . I may need the whole range. My question is: Why doesn’t Bullworker Inc. set up operations in India?? Have one outlet in India which supplies products to everyone in the region. It is a huge population and your profits will also be huge.

    Think about it.

  34. Ken Adkins

    I enjoy working out with my new Bullworker. Once I figured out how to put the springs in , it was a snap. One complaint is that it is inefficient to work the legs.

  35. Adam Worcester

    Steel bow is perfect home workout device: easy to use and portable. It delivers great results!

  36. Robert

    Great sturdy product! Definitely helping me get in shape! I am 71 years old and get a good workout using the SteelBow; without worry of injury. I strongly recommend this product!

  37. James G

    I purchased the Bullworker 2 (Green Handles) in the 70s when I was 15. I used it off and on and even brought it with me while in the military (after basic, of course). The strength gauge is long gone but other then a little rust here and there it still gets the job done. A couple of years ago I purchased the Steel-Bow to augment the variety of exercises. I can heartily recommend the Bullworker line. After over half a century still going strong! Isometrics is a proven method to enhance and build muscular strength. Don’t take my word for it, just search online for Mike Mentzer, Bob Hoffman or Ken Hutchins.
    My only issues is the Steel-Bow is less effective for some leg/back exercises (for me anyway).

  38. Martin

    Being pretty disappointed with a Bullworker form another company, I ordered the original one (Steel Bow). From the first moment on I realised the difference: This device is of excellent quality. Makes no sound, smooth mechanics and a pleasure to hold in hands to work with. The versatility of it is just amazing. Isometric, Isokinetic (IsoMotion) as well as Isotonic workouts are possible. Great device!

  39. Geoff Lucas

    Excellent quality product. Easy to use, very strong but light. Nice storage/carry bag with pocket for the extra springs. Will last a lifetime.

  40. Bruce Uhalley (verified owner)

    First class business. I recently told one of my close friends for many years, that it is sorta unreal that I am using my bullworker(s) in my room, over the age of 60, just like I did, when I was 15 years old, living with my parents. The Bow Classic and the Steel Bow both work, just like the barbell and dumbbell at the gym. After a lifetime of working out, I highly recommend this equipment, along with the business. They are truly first class on helping out and getting the orders to you.

  41. Michael N. Polimeneris

    I’m 63. I met and obtained my first Bullworker when I was teenager at 70’s.
    Since then, the 7-10 mins exercise with it became a MUST, non-omittable action every morning, before to get dressed to go to the University and later and till now at work, no matter what pressure of time I had/have.
    No need to mention that not my body condition, nor my health status show my age.

    I’ve bought and brought at end-of-life condition, due to normal/frequent usage 10-12 pieces, all models and generations during my life.
    Currently I have in use ONE BW in EVERY residency of my own, my main house in Greece, my country house in Greece and my house at Dubai and one more intact as hot-spare, in case one of them die suddenly, if this says something regarding my addiction to it.

    I’m in the market for another one (albeit, consnensus, it became a bit “salty” compared to previous generations), as one of the aforementioned shows serious signs of wear and tear.
    Frankly speaking, If I ever manage to reach at deep aging, part of it, sure, will be due to my genes inherited from my beloved parents but a big, maybe the bigger part, I’ll owe to this clever masterpiece.

  42. Raed Anani

    I was 18 years old, 5′ 10″ weighing 110lb In 1978 when I bought my first Bullworker. Within 2 years my wieght jumped to 175lb with zero fat. I remember having to lift the front of my VW Golf out of a trench all alone in 1981. Since then I have been using it off and on and now I am 60 years old still feeling muscular and powerful. I testify that this is an amazing fitness tool. I have bought the Bullworker 5 or 6 times in my life since I was gifting it to my dear nephews. I still have 3 of them. I don’t know if it has anything to do with using the Bullworker, but thankfully I don’t suffer from any disease. I whole heartedly recommend this to anyone who wishes to feel fit strong.
