First let me say that I was a fan of the bullworker as a kid and this is the same thing. It is isomertric exercise which definitely does build muscle. I would rate this product 5 stars but becuase of the horrible chart it came with can only give it three.

The reason why the chart is so bad is because in several instances the pictures don't match the exercise. I could not believe they would not fix this before selling it to the public. The point of having a chart with pictures is that once you get used to the workout, you can just look at the pictures and proceed, however, sadly after I noticed several of the pictures were duplicates, I read the paragraph below and realized they were describing a completely different exercise. Very poor practice for a product that is very good.

Got this last month and was so excited!. You see a lot of things TV but lately there has been an improvement in innovative products! I am 5'10" 190 and work out regularly. Yet this makes me sore every single time I use it. In fact, if I use it on a day I've done bench or significant upper-body stuff my arms will hurt for 15-20 minutes.

This really works. The quality of the product is so-so but its intended effect is there and you cannot get this workout anywhere else. Buy it! You may have to replace it in a year or so due to its plastic construction but its worth it.

I have used this for the past 3 months (all winter) on and off and see results with the use of this "car shock" type device. I do alot of modified exercises using this machine to hit target areas like upper and lower abs etc. It works. Its strong and very durable. Cant really get the chest to work out it mostly uses my arms when I try but that most likely my own fault.

It will not replace lifting if your trying to add mass (muscle) but it will make a huge impact if you use it HARD..

Peace!

The ISO-7X is an inexpensive knock-off of the bullworker, with the main difference being the nylon pull straps along the sides of the compression bar, compared to steel cords of the original. My biggest concern is its durability over time. I'm only on my 4th week, and have noticed the nylon straps have already started to fray slightly. For improved muscle tone with quick, light workouts, I think the ISO-7X will work okay. But for those seeking to seriously bulk-up, you may be better off with the bullworker in the long-run.

The instruction chart does not fully explain how to properly use the straps. There are two straps on each side of the ISO-7X. Grabbing a different combination of the straps allows you to adjust the extension of the hands/arms when performing an exercise that involves pulling. For example, grabbing both straps on each side and then pulling them outward results in limited movement with immediate resistance. The chart describes this as an "inner range" exercise. Grabbing two straps on one side, and the single INNER strap (closest to the bar) on the other side, is called a "middle range" exercise, where the arms can extend out further before full resistance is reached. Finally, a "full range" exercise involves grabbing one OUTSIDE strap, and the one INSIDE strap on the other side. This allows you to even more fully pull out on the straps before full resistance is reached.

As other reviews have noted, the chart photos are sometimes wrong. Pay closer attention to the verbal descriptions, which I believe are accurate. For exercises that involve pulling the straps, look out for the words "full range", "middle range" or "inner range" so you know which straps to grab.

I have owned Bullworker, and Bullworker like items for the last seven years. I used an original Bullworker a few years back to facilitate strength training for jogging. Then I started using the Bullworker as a stand a lone gym. In 2010 I spent two weeks in the Caymans and took my new Iso 7x with me. It was great for workouts.

I keep it in my class room if I am busy and down't have time for a "real" workout.

It works, it saves time, and it travels.

It's good for toning and building strength. The chart is confusing, I think it should of came with a dvd instead. Some exercises look exactly the same but the wording is different to make it seem as if its another in and of itself. Other than the obscure chart this bullworker does the trick. Prepare yourself to be soar afterwards because its a lot harder than it looks.

Usually when I am totally satisfied with the product and the service I rate the item 5 stars.

In this case I rated the product only four stars, but the shipper gets five stars even though shipping was four days late. The shipper credited my entire shipping cost back to my card becuse of the delay even though they shipped it the day after receiving the order. That's five stars to me taking responsibility for the service end.

With respect to the product the ISO 7X product. I agree with some of the other reviewers. This is a Bullworker where the vinyl covered steel cables were replaced with nylon fabric straps that will eventually snap for the body builder types. However I am 56 years old and suffering with Polymyositis, Dermatomyositis, Fibromyalgia, and Sjogren's so it will probably l;ast me forever. But I gave it 4 Stars because the Bullworker was a better product that lasted a lifetime, but it cost me more even in 1970s. So I got what I paid for.

I don't know what the previous complaints were about the wall chart, it was perfectly understandable to me. Anyone using their left or right side of their brains should find the instructions and pictures perfect.

As far as having grips and a carrying bag, I agree with the other reviewers it should have come with the ISO 7x Delux. So being relatively happy with my product and the previous service outcome, I ordered the carrying case and grips last night. I would have ordered it all at the same time, but was not sure if it came with the original package. The total cost is still a good price, but for you power builders, you may want to consider a unit that is more ruggedly constructed with stainless steel nylon covered cables at the much higher cost.

I just received this product a couple days ago. I was able to buy it on ebay for $30. I wanted something I could use in my dorm room but also something that could work out the entire body. This product is a great workout. You definitely feel achy the day after from working your muscles. This product comes with an exercises chart that lays out a 6 week plan. there are 5 exercises for the first week (working out the chest, biceps, back and legs) and during the 2nd week you add 2 a day until you reach 36 exercises. After 5 weeks there are about 20 or 30 more advanced exercises. The only thing I wasn't sure about was how many reps you are supposed to do. The first couple days I did 10-20 reps each because there are only 5 exercises for the first week. The product is pretty smooth and easy to use. The only problem I had with this product is that a couple of the exercises are very hard to do because the bands are not very long. In the commercial there is a curling type exercise but I am 6'3" and I can't see anyone being able to do this unless you are extremely small. but besides that It seems like a great piece of equipment and very durable. I would definitely recommend this product.

The Iso 7x Deluxe Edition is a good sturdy built machine that delivers a good isometric workout. It's steel and the plastic handles seem hard enough that you won't break them by use. They probably would break or crack if you dropped it on a hard floor.

The reason I only give it three stars is because there is not enough information for using the machine. The workout chart has duplicate pictures with the wrong information for the picture. There is also no mention of how many reps to do. It would be much better if it came with a booklet or workout cd. But for the price I paid I am happey with my purchase.
