Some of the older Bullworker training videos from the 1980's are funny. They are good, but cringeworthy. The cheesy looking men, and women in their 80's leotard attire. lol. Don't get me wrong, I actually think the Bullworker is a pretty good piece of training equipment, and I would definitely consider buying an older model. Lot's of training guides in the form of PDF's and infographics (charts) are out there too.

Used vintage Bullworkers can be found for sale cheap on eBay. One like the guy is using in the video would be good enough. That's one of the older models with the green handles (called the Tensolator I think). There's also the older model with the brown handle grips (original?). X5 is another good older example. https://takoona.blogspot.com
