In any local CrossFit Box, you will see a Workout of the Day (WOD). In that WOD there will likely be components such as a gymnastics move paired with a cardio exercise and/ or a weightlifting exercise. There will also be a "as prescribed" rep scheme or weight. For example, I will use a benchmark workout consistently used in the CrossFit community. The workout, "Cindy" consist of a 20 minute AMRAP of 5 pull-ups, 10 Pushups, 15 Air Squats. The idea is for the athlete to work for 20 continuous minutes attempting to get as many rounds and reps of those three movements in that order as possible. If an athlete on a good day can only complete 3 pullups until failure attempts "Cindy", they would get through one round and spend the next 15 minutes pursuing 5 more pull-ups. So what is solution? Two ideas come to mind; first, the athlete should spend more time on their own developing the strength and force output to do more than 3 pull-ups. Secondly, scale the pull-up movement during the Met-con. A banded pullup or ring row are both good options. The workout is meant to last 20 minutes of continuous movement and test the athletes muscular endurance. If the athlete only completes full rep pull-ups and can only get through 1 round in 20 minutes, then the athlete is missing out on what the workout is meant to test. The athlete could substitute the pullup with a ring row and work for 20 minutes and establish a baseline. The athlete could then work on pull-ups during the time until the next "Cindy" workout. When the workout comes up again for retest, if the athlete is proficient at pull-ups, they can complete the workout as prescribed and note that as a comparison compared to the scaled workout doing ring rows. From that time on, the athlete can complete the workout with pull-ups and compare to the previous attempt at the baseline. Now the athlete can produce the force and can expect to produce that force quickly. The test then becomes for how long can the athlete sustain that force?
