We introduced a new logging system in December of 2012. That new system required us to "enhance" each of the site's workouts over to the new format. Unfortunately, because we have so many workouts in the system, we were unable to correct them all. If you ever come across a workout that needs to be upgraded/enhanced, email support with the workout ID and they'll get it taken care of for you. If you are using the website you'll know the workout hasn't been upgraded yet if you see the orange "Legacy" icon next to the name of the workout.

You can still log a result for the workout but you'll have to use the old, or "legacy", builder. It won't be as intuitive as the new system, but it'll do until we are able to enhance every workout.
