Clean Grip Deadlift
Build over the first four sets. The fourth set should be tough but submaximal, leaving two good reps in the tank. The fifth set is 10% lighter than the fourth.
21-15-9 For Time:
Extra Work: Double Overhand Deadlift Hold
3 x Max Effort 50-60% of 1RM Deadlift OR 40-50% of 1RM Deadlift
Higher end of the loading range is preferable so long as the you can get a decently long hold (15+ seconds).
