Are you working on your Maximum Effort lifts? If not, you need to start adding in some days devoted to heavy lifting. CrossFit is NOT just the metabolic conditioning workouts. To be a well rounded athlete (or whatever we call ourselves)you have to be able to move a heavy external load. Preferably very fast, hence the bias towards Olympic lifts. High rep cleans or snatches with a kettlebell or dumbells are great, but very different from max effort training. I injured my wrist a while ago, so am unable to hold any significant weight in the rack position. Effecting my overall progress? You bet, although I will work around it to be in a position to move on when the wrist is 100%.
