Try this variant (video here: https://www.instagram.com/p/B5LRYk6jUWm/) wherein you have some assist to keep from rotation; but aim to place the “non-working” arm at an angle where it can’t provide tons of vertical assist. I’ve also used the side of the cage previously. With this barbell in front at shoulder height and extended arm, this is helpful placement to reduce body rotation but prevent from excessive vertical assist.
At 250lbs, even the assisted version showcased here is right at limit. These low rep high intensity efforts are a bit at odds with my current program, hypertrophy for six more weeks. But this would be a solid regular program addition for those in a max strength or peak phase. Enjoy.
