There’s a reason why they use the term: Summer Legs
For NBA players there is a clear perception of what a proper off-season can do for their performance. An off-season that takes into account all of the weak areas of that particular athlete & puts a plan in place to address them.
As we mentioned above there are critical qualities that we can’t train effectively during the season. This is because these qualities take time & energy to recover from. If we tried to do them in-season we would simply be too fatigued. But in the off-season, we can re-focus our attention.
In case you don’t believe us look at the example to the right. You will never see Steph doing this in-game because he simply plays too often to be able to sustain jumping performance like this at his genetic makeup, however, if his season was shorter & he had a bigger off-season, perhaps this would be a regular possibility for him.
