Option 2:

The offseason schedule is really a good question, and it really kind of comes down to what the player needs at the time. I think pretty much everyone will unanimously agree that being a professional athlete is a year-round deal in this day and age, so personally I don't even think spending half on and half off is really a good way to prepare, you probably want to keep on top of your fitness even when "off" just so you don't have to build anything back up when you come back. I think the right way to look at it as basically being a full-time athlete for 10 years, and then getting to rest for the next 50, so the summers will include some breaks of course, mental strain and some injuries require at least some period of full-rest to recover, but the length and amount of rest is probably best to determine year on year with the help of some professional physical therapists or specialized doctors depending on the issue. I think you have to use all your resources to get you through the summer well and hopefully come back into the next season at the same level you want to be at all year, otherwise you will just be making it harder for yourself. You only have to do it for like 10% of your life, so you might as well try to not hinder yourself by over-relaxing unless it is really needed.
