@deadshot138 Are you doing conjugate? I remember deloading when I was doing it, but I can't remember how often. I think also depends on what you consider a deload. I know there were like a a week where we just drop volume (but keep intensity high) or drop intensity (but keep volume to par). Not sure if that's considered a deload, but overall tonnage drops that week. The only time I can remember taking almost a week off (just doing light stuff and cardio) is after a meet. The program I"m doing right now has 'low stress' weeks at week 1 and 7, which means the volume drops, but intensity remains high. For week 7 I basically still hit all my top singles, but back off sets are reduced. Or if just working with reps, overall sets will be less for each exercise.
I also wouldn't let missing that max attempt get to you, especially if you feel you are in the ballpark based on your recent training. Just stick with your program and peak for it when the time comes.
