I think the offseason should be a mix of training to stay in shape and relaxing for players. Of course those athletes are paid absurd amounts to play hockey but constantly training and practicing takes a huge amount of time so spending time doing what they enjoy, relaxing and spending time with family is just as important as physical training. I actually don't know what I'm talking about but it just seems to me like there is no correct way to do it so it's fair enough to spend a week doing absolutely nothing to recharge your batteries after a tiring season and then you can just go back to the place you call home and spend time with your family while training enough to not lose too much muscle mass and once you're closer to the season, train more in hockey related exercises to get rid of some rust.
