Years of being told to “hydrate, hydrate, hydrate” caused first-time Ironman athlete Dan Fontaine to overlook the dangers of overhydration.

He had been training for his first Ironman for 12 months. Dan Fontaine thought he had done everything right.

“The only problem was my plan had a big flaw,” 32-year-old Fontaine said almost five years later.

It never occurred to Fontaine that drinking too much during the race would dilute his blood-sodium levels to the… Continue Reading

Olympic gold medalist Simon Whitfield reveals how elite triathletes figured out widely held hydration guidelines are wrong.

When Simon Whitfield competed in the 2000 Sydney Olympic Games—the first to include the sport of triathlon—the information he had about hydration was confusing at best.

Lon Kilgore reviews academic literature on periodization from 2000 to 2015 and finds little support for the NSCA’s contention that classical periodization is superior.

Academic evaluation of periodized training has historically been quite limited, and very few experimental papers on the topic were produced before 2000. Attention was firmly affixed to endurance training for heart health as weight training and high-intensity training were not accepted means of improving cardiac… Continue Reading

In the spring of 2013, Kelly Starrett and his wife, Juliet, volunteered to help out at their daughter’s elementary-school field day in Marin County, California. The experience was eye-opening.

Top scientists bust hydration myths at the 2015 CrossFit Conference on Exercise-Associated Hyponatremia.

In 1998, Dr. Dale Benjamin Speedy stood in front of Ironman competitors in Auckland, New Zealand, and prepared to make an announcement he knew was going to be unpopular: He told the athletes he was reducing the number of hydration stations throughout the race, which was made up of a 2.4-mile swim, 112-mile bicycle ride and 26.2-mile run.

“People freaked out,” said… Continue Reading

In Part 1 of this series, Lon Kilgore examines the research behind one of the sacred cows of strength and conditioning.

Periodization is king of all exercise-programming methods.

Classical periodization, the English translation of Leonid Matveyev’s Soviet model of programming, is the single best model and should be used in all strength-and-conditioning training for all healthy and athletic populations.

What if almost everything you know about hydration and sports is wrong?

Dr. Tamara Hew-Butler, a devoted marathon runner and sports-medicine podiatrist, was working in the medical tent at the 2000 Houston Marathon in Houston, Texas.

“It was hot that day,” Hew-Butler said, “and all these runners came (into the tent) and collapsed.”

Hew-Butler and her colleagues knew exactly what to do. Assuming dehydration, the medical aides started IVs for the collapsed runners. Then something strange… Continue Reading

Strong shoulders are the key to performance overhead, and four simple movements can help you improve mobility and stability.

A look back at the workouts from CrossFit.com for the 2013 year reveals that over 80 percent of them involved at least one exercise that had a transfer of force through the shoulder girdle.
