I don't know how desertcart did it, but you can't order this package off the Bullworker site ( as of this writing). Everything is sold separately. With this package, you get the bow, 3 workout charts (worth $12 each), the eso ($9.95), the bow extender ($19.95) and two dvds ( $19.99 & $12.99). While there is no super saver on the shipping, desertcart's shipping is about $5 cheaper. So you are saving $103.88 with this package. You also get a great bag to fit everything into that you can sling over your shoulder or put into a suitcase. The steel bow is made quite well. I've never owned a Bullworker. I'm not a hard core weight lifter. I am hoping to use this so I can skip the gym. I want to tone up and build some muscle without bulking up. I haven't been able to locate any reviews by women. Some men have mentioned that their wives and daughters also liked it. If there are women who are using it, I sure would like to hear from you on what you are doing. From all the reviews I've read on various sites, this seems to be very effective at doing what I want and more. I must confess I'm a bit skeptical because I don't see how this small device can deliver so much. However, the BW has been around for 30 years, so I decided to order it, as its longevity speaks volumes. I haven't used it yet, but will do an update. I wanted to let readers know what a great deal it is and would recommend it, if they are in the market for a Bullworker for a holiday gift, for someone else or themselves. Stay-tuned.... Update: This little device is NOT going to the thrift shop. I don't like lifting weights; too many sets, too much time, uncomfortable positions. The BW eliminates all of this and really tones your arms, shoulders and chest FAST. I'm talking about 3 times a week, a half dozen moves, done 4 times each. Not 4 sets, 4 moves. I decided not to take measurements, just do it. The BW has a gauge on it and I could barely move it in some of the exercises. I now get my motivation from seeing the gauge move higher and higher and looking in the mirror. There are 2 DVDS, one is done sitting, the other is standing. I don't like squats and lunges, and so I prefer the sitting DVD, which is quite a workout for 1/2 hr. My legs easily bulk out and I'm not saying the BW bulks out your legs, I just prefer doing Callenatics because it works. Lastly, I don't like situps, planks or leg lifts. If you haven't figured it out, I know what I like and what I don't. I want things that work and that I like doing. Well, I really like the ab exercises with this device. Not hard on your neck or back, nor uncomfortable or awkward positions. There are numerous exercises, 3 different ways of performing them, and 3 springs to increase resistance, so you won't get bored. But, I don't think I'll ever get bored with it. I'm so happy with how my upper body is looking with so little effort, and each time I do it, it gets better. Second update: I am smitten with this device. I continue to use it and my shoulders, arms and chest continue to take shape. I use it every other day, maybe for 10 minutes, often while watching tv. I really got a wonderful surprise when I took a yoga class. I discovered that I had developed a lot of strength in my arms and shoulders and was able to do poses I couldn't do in the past. I'm really happy about this development and now I'm enjoying yoga 3 times a week. Review: 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. ## Features - Bullworker Steel Bow 20” - A game changer for on-the-go workouts.

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 ### ⭐⭐⭐⭐⭐ BEST DEAL FOR YOUR MONEY, GREAT FOR WOMEN *by T***N on October 11, 2012* I've looked around and this package is the best deal for your money.

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. ## 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.
