Well after taking about 6 months off from the gym, I spent the last 3 weeks going light for 2 sets of 10-12 on my lifts. I used that time to get the "feel" back and make sure I was getting good range of motion, etc.
Today I got after it. 3 sets of 5 on my lifts at around 85% of my 1RM. Everything went pretty well except for my squats. I felt a twinge in my left knee on my last set. I racked the weight and moved on. No troubles after that.
