As an endurance athlete who has shaved minutes off her 5K, 4-mile, and 5-mile times since starting CrossFit, I challenge any endurance athlete on this myth.
Before joining a CF gym, I thought it was nothing more than HIIT-style workouts.
Though there is a lot of "high-intensity interval training" in CrossFit, there is plenty of aerobic training for die-hard endurance junkies.
And I know the prospect of putting on weight is unnerving to a lot of endurance athletes.
You want to remain as lean as possible so as not to carry any additional poundage throughout a race.
However, with developed strength comes a developed ability to not only carry that newfound muscle weight, but to use it to your benefit when you need bursts of power and quick recovery.
