In parts 1 and 2 of his lecture on CrossFit programming (i.e., putting together effective training and workouts) in the last two month's video articles, Dave Castro explained the proper application of the principles of variety, intensity, and functional movements. This month, he goes into more detail about how to construct effective workouts using combinations of functional movements. Find out why seemingly simple couplets and triplets are the cornerstone of some of the most effective CrossFit programming.

Next month, Castro will explore how to create and implement single modality workouts as part of your CrossFit training.
