Working Out Injured. Yes? No?

Being a personal trainer in Las Vegas, I run through a ton of situations. People who work out for fitness, people who work out to look good for the pool, people who work out to fix faulty movement patterns. The list goes on and on. But what happens when those same people are nursing an injury? Should they keep working out to acheive those goals? If you have a broken leg, and your goal is to ride in the Tour de France, you might want to rethink some things. Depending on what your goals are, you should cater to them, and modify your workouts that way. For example, I am having some issues with my shoulder. I have had them for a few years, but up until recently, they have been an afterthought i always worked out how I wanted to, but over the years, have stopped doing bench press, and shoulder pressing, because i feel a lot of shoulder impingement when i do them. So i have substituted other exercises where I don’t feel the pain in my shoulder. Right now though, it has really been bothering me, and I know that no resistance exercise is going to help heal it. So I’m laying off of it for a month. Now, what I am saying is, you need to feel for yourself, along with a professional opinion, what would be right for you. Should you continue to work out with minor injuries, or should you take a rest and see if that helps heal them. Always ask this question before you just jump to an answer.
