If that's the case then I think a better warmup is needed and you need to add more weight as it sounds like you are not stressing (i.e eustress) your muscles enough with the weight that you are currently using.
Do you recommend some kind of cardio work (like, say, 10-15 minutes on the treadmill/bike/stepper) before lifting as a warmup? I normally stretch for 3-5 minutes and then start lifting.
