If I have any sort of injury I immediately stop training until it has recovered to a certain point. However, once I start training again, the injury often feels better after a session than it had done before.
Clearly if you're in pain when you train with an injury, this is bad but there seems to be some middle ground where training can actually aid recovery. I'm guessing it must be increased blood flow or something, I don't know.
So what do you guys do? Train what isn't injured, train thru the pain, rest or something else?
