Hi so I will give some background as to what I have been doing recently. About two months ago I worked my squat up to about 260 3x5, but I hurt my back in the process. Spent the last two months rehabbing and I did Bill Starr's 5x5 for my bench press, but just did 135 squats for flexibility. Anyway, I got my bench up to a solid 240 on the monday set, and 250 on the friday 3 rep set.
My back started to feel better around a month ago so I have started heavy squatting again. I decided I wanted to gain about 10 more pounds so I have been drinking a lot of milk. My squat today was already 270 for 3 sets of 5. However, I couldn't even do 225 for 3 sets of 5 on my bench press. Even the first set was a struggle. I am doing starting strength now by the way, mainly to increase my squat and military press. I assumed this would lower my bench slightly, but not by this much. I believe it has to do with the fact that I am absolutely gassing myself on my squat sets. Has anyone experienced this? FYI, I am 6'5" 225 and have gained about 5 pounds in 2-3 weeks. My military press and squat are both increasing every workout but bench feels horrible .
