November 01, 2007

PDF Article

In 1996, Dr. Izumi Tabata published the results of a study demonstrating, with speed skaters, that the aerobic and anaerobic pathways could be trained simultaneously (Medicine and Science in Sports and Exercise 28). This was a significant finding, as most authorities had regarded the two pathways--and training for them--as compartmentalized. Aerobic training was largely long slow distance (LSD) work, and anaerobic training was typically regarded as some… Continue Reading

CrossFit workouts emphasize high-skill movements (relative to isolation and/or machine-based movements) because they are, in almost every respect, better vehicles for optimizing fitness--for achieving CrossFit's mission of increasing work capacity across broad time and modal domains.

In this lecture from a recent CrossFit certification seminar, Greg Glassman looks at the differences among the shoulder press, push press, and push jerk and compares them to the differences between strict and kipping… Continue Reading

Bad form is bad in every way. Citing specific examples from lifts, Mark Rippetoe co-author of Starting Strength and owner of Wichita Falls Athletic Club/CrossFit Wichita Falls, writes that what constitutes bad form is not a matter of opinion.

Bad form occurs when a movement pattern is executed inefficiently. The bar is moved by incorrect biomechanics. Instead of all the muscles in the system making their anatomically… Continue Reading

When I was training as a wrestler for the 1992 Olympic Games, the jump rope, along with many of the kinds of functional training exercises embraced by CrossFit, were the keys to my development into one the quickest, most explosive, and most highly conditioned wrestlers in the world. I believe that CrossFit's fitness principles of functionality, intensity, and variety are taking us back to the basics and setting the standards that can help our… Continue Reading

An Explosive Combination

August 01, 2007

PDF Article

Early last month I launched the third volume in my Dumbbell Moves DVD series. It was a momentous occasion for me, as it pulled together several concepts I had been working on since before I began Volume I. And it was especially rewarding because I had the assistance of one of the first prominent CrossFit athletes--two- time skiing Olympian Eva Twardokens--demonstrating the combination moves for the DVD. What a treat! The series is dedicated to… Continue Reading

As you look everywhere in the sporting world you see athletes performing sports with a rotational component. In sports such as baseball, tennis, and golf, the athlete must transfer ground forces through the middle of the body to the upper extremities. Without getting into physics involved, suffice it to say that those with weaker rotational strength and experience will not be as successful and will most likely end up with aches… Continue Reading

PDF Article

While standing in a grocery store line the other day, I picked up one of the popular mainstream men's fitness publications. (I confess.) They are all the same. The models are topless, lean, and tan. Their makeup jobs take longer than those of all the girls I like, and their teeth are bigger and whiter than Mr. Ed's. To my utter amazement, though, the models in this particular issue were performing functional… Continue Reading

Now that you have had thirty days since last month's dumbbell article to work on your plank position, push- up and row, and vertical to horizontal movements, it's time to add other plank variations to the mix. I consider these to be more advanced, as they intensify the requirement to maintain a tight plank position with no sagging or piking. This article and its demo videos assume mastery of the plank… Continue Reading
