Longish day. I have been up since 2am, with may be 3 hrs of sleep. I was tired going into the lifting session at 10;30pm, so took my time between sets, did a little more of the warm ups, and the entire session lasted 70 minutes. But I hit the weights and reps I had in mind, and that's what matters at the end of the day.
Just take care you don't get injured. It is good to take some more rest between sets as you already did. Job very well done.
