Hey Jamie!
I prefer to lift on MWF but sometimes it just doesn't work out like that for me! As long as you don't lift the same body parts on consecutive days, you are fine. Example: don't do arms on Fri and Saturday. Give your muscle groups some time to rest.

I also will lift at night and do cardio in the morning on the same day. I have never had a problem with that.

Hope this helps!
Linda
