That's not to say you can't get a great workout or even get in the best shape of your life after 40! You just need to make sure not to over-do-it, listen to what your body is telling you, give it plenty of rest and don't make an injury worse by aggravating it by doing the wrong exercises.

Try changing up your program and finding alternatives that are more comfortable for your body and its quirks. Always start out light, even if you have to add a few sets in before you move up to heavier weights. And make sure you don't go too heavy and cause an injury that could put you out of action for a few weeks or even months, it's just not worth it in the end. Pushing mid level weight can build muscle just as well.

Make sure to stretch and not before you workout, do it during. The best time is right after you have done a light warmup set. After you finish up an exercise, stretch that muscle a bit more.

You do need to push yourself but there will be times when you just need to take some time off, you'll know, just don't take to much time off or it can get really hard to get back in the routine. I like to take two to three days off when I'm felling burned out, any more and for me it gets hard to jump back in.
