Bill Dobbins on Gunnar Rosbo

Gunnar Rosbo was introduced to bodybuilders all over the world in a 1983 Muscle and Fitness magazine article by Jack Neary called “Arnold Who?”. Click here for an excerpt. It was followed up by a Rosbo arms training article by Bill Dobbins. Here’s an excerpt where Mike Mentzer is mentioned as a fan of Rosbo:

Mike Mentzer is one of Gunnar’s admirers. The feeling is mutual: During his 1982 California visit, Gunnar constantly sought information and advice from Mike who repeatedly brought friends to admire Gunnar’s amazing arm development.

“The first time I saw Gunnar was the 1977 Mr. Universe in Nimes, France,” Mike recalls. “He showed considerable promise even then, but his arms caused him to really stand out in memory. He weighed only 220 pounds, about 20 less than now, but even at that weight his arms were gargantuan.”

The article goes on to mention that Rosbo got into bodybuilding initially because his brother-in-law was a bodybuilder. Writers for Weider magazines must have been commanded to force the “Weider Principles” into their articles. To quote: “Gunnar achieved his growth through a very traditional approach to training, learned for the most part by studying the Weider Principles in M& F and by observing the Weider champions training in Europe.” Later in the article it allegedly quotes Rosbo: “Using the Weider Priority Principle, I am spending more time and effort on bodyparts I think are lagging behind.” Does anyone think Gunnar Rosbo or any bodybuilder has ever attributed the “Weider Principles” to their success or brought them up seriously in a conversation? Bodybuilders are more likely to adhere to and tout the Built Report Principles. Here are the Built Report Principles. If you could train yourself to think Built Report Training Principles whenever you read “Weider Principles” we’d be grateful.

The article reveals Rosbo’s arm workout which involved 20 sets for both biceps and triceps, frequent supersets, and 8-10 reps per set to failure. It also says Rosbo flexes and poses between sets “to reach deeper into the tissue, pumping the area thoroughly and forcing every single muscle fiber to become involved in the movement.” Built Report did an article on incorporating isometrics into workouts. Rosbo continues on about isometrics:

“After my workouts, whether I am training arms or another bodypart, I also take some time to pose. A bodybuilder who poses and flexes his muscles, as well a simply training hard, looks harder, more chiseled and better shaped than one who does not.”

Dobbins writes that Rosbo spends about 40 minutes training triceps, 45 minutes training biceps, and about 10 minutes when he trains forearms, which he only trains on occasion. Apparently Rosbo was incorporating the Built Report Priority Principle since his forearms were already an outstanding bodypart.

Yes, of course Rosbo had good genetics for muscle mass and his arms would respond quickly no matter what he did but it is interesting that he incorporated isometrics into his workout which not a lot of people do but is a good idea.

Little has been printed about Rosbo and Built Report is a Rosbo-friendly website so maybe Rosbo or someone connected with Rosbo can give us information on what he’s up to these days.
