The Power Twister Bar was heavily adversited in the old bodybuilding magazines in the 70s. You’d see in the ads Arnold Schwarzenegger, Chuck Sipes, Frank Zane and Dave Draper advertising. This kind of widget is very oldschool.
Don’t forget to check the “Chest Expander” article. It was back in the day very popular too.
You can use the Power Twister for various muscle groups: chest, shoulder, arm, wrist and hand backand here I am presenting an exercise chart from a bodybuilding magazine (from the 70s), have fun.
