Sports, and specifically sports training, has come an incredibly long way from where things originally started. Back in the day, guys didn't even lift weights and probably never bothered to go for a jog if they could avoid it. Now guys are doing altitude training or spending half their time in the hyperbaric time chamber in order to get ready for game day. For Jon St. Ark, the position of goalie is so different from the rest of hockey that its important he trains using some other methods to keep his skills sharp. One of the sports that he enjoys playing the most is actually tennis. Running across the court is a great way to build up lower leg strength, while also requiring an extreme amount of body control in order to have crisp reaction times when sitting in net. Plus being able to enjoy the game outside instead of a dark arena is a nice bonus as well. And the outfits are pretty snazzy.
