For strength training StrongLifts seems like a good program. It used to be highly recommended on the fitness reddits, but I haven't followed them for a few years. Regardless, I think it's a solid program for starting strength training. I do more of a bodybuilding/bro split, but I've been mixing in a couple of heavy days modeled after the StrongLifts plan. It's certainly simple if nothing else.
