You gotta put LeBron James on this list. Heavy lies the crown for King James, but he’s not pressed to keep the workout regime that keeps him on top a secret. The hard part is not cutting corners. 

James acknowledges that the offseason is “the real season.” In this workout video, trainer Mike Mancias sees the court like a grid, and has James hit a certain number of jump shots per spot. Later in the season data collected during these sessions will end up on his shot chart. Basically, James focuses solely on shooting, dribble-drive moves from the top of the key, and shredding his muscles with elastic band stretches and rapid fire jump rope. Review this video of LeBron’s offseason training to realize why he’s a 4-time MVP.
