I've been doing SL's 5x5 for 4 1/2 weeks now and am seeing great strength improvements. However I seem to have stalled. I'm up to 305 in squat and have been stuck for 4 workouts.
First day I got to 305 I was able to do the 3x5 easily, the next workout I tried to go 310 but was unable to do even put up two solid reps, I lowered down to 305/295 and could only do 5 reps of each. Next workout, easily did the 305.
I really don't understand what's going on, if anyone has any ideas on how to get past this I'd love to hear your opinions.
