>>I have been playing tennis all summer without any physical injuries.
>>Then in the fall joined an indoor club. Found some very hard-hitting tennis partners. And after 2 months of playing, developed a very painful condition called Golfers elbow. I have never played or cared for golf so I am upset that I have to explain in detail where it hurts and why it is called Golfers elbow :) Now I need to take at least 2 months off tennis to make the elbow heal completely; or I keep re-injuring it. I have had exactly the same problem about 5 years ago and it took a year (of icing and anti-inflammation medications to heal it). Maybe time comes to switch completely to pickleball.

>Philosophy aside, the most important exercise-related thing I've found in my adult life is that I need to stretch before any significant exercise or exertion. With that, I'm never sore the next day; before, I always was. YMMV.
I agree that stretching is important. Although a new trend, Active Isolated Stretching, is even better.
