I acquired it, I would never purchase one. I have always wanted to handle one and compare. And so I have. I will state right from the start that the Bullworker Bow Classic is a superior Bully in every way.
1. The Bully X's handles are very small, smaller even than those of the older Bullworkers'. They are made of a hard, smooth plastic, making them somewhat slippery. The handles on the Bullworkers are much bigger and their non-slip rubber laminate makes them a pleasure to grab hold of and grip.
2. The Bully X is way too stiff. I must have gotten v.4. You couldn't turn around to where Bert wasn't advertising a new improved version. Last count he was up to 4. I believe his only "improvements" have been to up the resistance on each version. Well, there comes a point to where it is no longer a valid live iso exerciser. I mean, too much resistance defeats the whole purpose of the Bully if you can barely budge it. Funny thing, though, the resistance is much less when pulling on the cables. Wonder why?
3. There is a squeaking, clunking noise when compressing the Bully X, like the older Bullworkers. The tubes are a bit rickety, also like the older Bullworkers. It doesn't employ the same latest technology that the Bullworker does, making compression smooth and quiet.
4. I was particularly interested to see what the difference is between the Bully X's 3-tube design and the Bullworker's 2-tube design. Bert makes much ado of those two independent tubes on either end. In compressing both Bullies, I found that there is no difference at all. I mean, all the resistance is essentially channeled down a central shaft, so it doesn't matter if there are 2, 3, or a dozen tubes.
5. The sliding plastic rings around the Bully X are narrow, flimsy and somewhat loose. The ring around the Bullworker is a solid, wide, form fitting transparent plastic with a red line running around the middle, making it easy to see your mark.
6. The gauge on the Bull X is a colorful, almost cartoonish plastic laminate. There are already signs of it beginning to buckle in spots. The gauge on the Bullworker is etched in steel and has a more professional look to it.
7. The Bully X has no handles on the cables. This is a biggy. The moveable, contoured rubber handles on the cables of the Bullworker enables every exercise to be performed to the max due to hand comfort.
8. The carrying case for the Bully X is a bit chinsy looking with a flimsy plastic window covering one side in its entirety. I suppose this is so that you can see the Bully X within. The material on the other side isn't as heavy as that of the Bullworker, and the zipper is no where near as heavy duty as that on the Bullworker carrying case, and it doesn't open up nearly as much. The Bully X name along with a biceps-flexing bulldog are silk screened on the case. The Bullworker name is embroidered on its case. The Bullworker carrying case could be compared to a top-notch back pack, and The Bully X's carrying case could be compared to something you'd get your little kid.
So, there you have it. Anyway, despite Bert's claims, in the guise of Frank Sherril, Army Ranger extraordinaire, that he invented the Bully X, it is actually the Super 4 sold in India.
