I used to train 2 days a week with Bench/Squats on day 1 then Press/Deads on day 2. For the most part, all of my lifts progressed about the same. I would rest about 10 minutes between the two lifts. I set many PRs with that type of training. Eventually I did switch to 3 & 4 day training. Progress and strength gains continued. Like BtB said, it just takes a little time for the body to adapt/adjust.
Success comes to those who persevere, not to those who complain and give up
I just want a place where I can be left alone to get strong and work off some aggression.
The greatest danger for most of us is not that our aim is too high we miss it, but that it is too low and we reach it.
