The CrossFit Workout of the Day, or the WOD as it is commonly called, is the heart of a CrossFit workout routine. Varying from day-to-day, the WOD mixes up the CrossFit workout routine and utilizes HILT and strength training. The WOD usually requires that the CrossFit member complete a certain number of exercises and reps as quickly as possible, OR to finish as many reps of a certain exercise as possible within a time constraint. The WOD is dedicated to pushing oneself on a daily basis as well as to assist members in achieving ultimate fitness.
