This is the fifth part of the Programming lecture from the CrossFit Level 1 certification seminar at CrossFit One World in Union City, CA on May 11, 2008.
Dave Castro covers the two main workout types: Task priority and time priority. In task priority workouts, the total work is fixed, with the time it takes to complete up to you. In time priority workouts, the time is fixed, with the total amount of work completed up to you. Fitness is the ability to do more work in less time. It's essential to program exercises, loads, and reps with this work/time relationship in mind.
