Of all the bullworker type exercisers I have found that the Bully Xtreme 2 offers: * Greater resistance than most others I have tried. * A lifetime warranty... none t the other Bullworkers have this.. 5 years seems the longest they will do. * Comes complete with a training manual, weight loss program, individualized meal plans * And finally the thing I lied the most is it has a 120 day money back guarantee. Cons: The resistance is definitely tough so I dont suggest that a very weak women purchase this. For men it's perfect. My 2 cents.

bullworker x5 and bully xtreme2 are pretty much the same item but manufactured by competing brands. the bullworker steel bow is a smaller version of the "bullworker classic" and just as helpful. so out of those three, in my opinion would be the bullworker x5 or the bully extreme2 just in terms of the varieties of exercises the 4 straps allow and the two inner handles. between those two i would say the bullworker x5 is better quality but both would do the job well. the steel bow is great for taking with you and it's also good to target certain muscles that the much longer regular bullworkers don't give you as good access. if you are planning on buying one but have never used a bullworker type of exercises, what i would suggest is to go to ebay and buy a used bullworker. they're around, you can get one for about half the price of a new one and unless you left your bullworker buried in a pit of acidic mud, a ten or even twenty year bullworker is about as good as a fresh one of the factory. the used bullworkers are usually variations of what is now known as "bullworker classic". and in the end, i would suggest you get one and use it. yes, they do work.
