A recent surge in popularity has brought different strongman training methods into mainstream facilities. While this is largely a good thing, it also requires an understanding of what the heck these exercises actually do.
McGill (2009) showed that the lats are very important for a lot of the carrying events such as the farmers walk due to their role in stabilizing and compressing the spine for additional support as well as providing a co-activation potentiating effect for the prime movers.
A fist is way stronger than any of the individual fingers, so getting the muscles to all work together helps produce stronger contractions. The two-barbell variation really lights up the lats for this reason.
Dr. Ken Kinakin, much like Dr. Mike Leahy, knows your pain. In fact, he's made a living off of it. The doc is one of the best in the world at devising training protocols to help make you injury-proof. Yeah, he likes bodybuilding and powerlifting routines, too, but when it comes to figuring out how to fix what ails ya', he's one of the best.
Mike used to like Functional Training. He used to think Mike Mentzer was kind of a bonehead. Now he's not so sure about the former or the latter, along with a whole lot of other things. If his current rate of "unlearning" continues, he soon won't know anything!
