If I understand Figgs, he didn't do DB presses for 3 weeks? If so, than most anyone will not hold the same (or better) strength level inbetween that time period. You must train the muscle/nerves motor units to keep the lift tuned for their higest responce and strength. I believe that anything over a 2 and a half to 3 week period the body loses that edge. Even if Figgs did military presses or any other shoulder exercise, in most cases, if the actually lift was not done he will lose strength in that lift. Usually though, a person can come back even stronger than he was before taking that 3 week break on any lift. So maybe in a couple of more DB press workouts Figgs will be using 80lbs for 10 reps. Seen this happen a lot to other guy's on other lifts.
Of course we all have off days when the weight seems twice as heavy and we just can't seem to get kick started no matter what we do. But I don't think this was the cause in Figgs case. If anyone has a day like this, than instead of wasting a workout, try a lighter weight for more reps to get you going. Example: if your normal workout is 300lbs for 8-10 reps in the BP, than try 200lbs(or less) for 12-15 or more reps for a few sets. Sometime this can't get started feelings can be mental as well as physical. When rep'ing out and getting the blood flowing, the urge to begin training may returns. Good Luck.
