The USS Mihoshi: Holodeck 2
After getting off duty, Jason made his way to one of the holodecks being unused. He had stopped off at this quarters and changed out of his uniform into some workout gear before heading there. As excited as he was to be doing something besides patroling a virtual graveyard the ship had been till it reached DS5, he was more than happy with things are they were.
Jason loaded up a program he had been using since the Mihoshi had left dock. Once it was finished loading he entered in to a room with mirrored walls, flat mats and some obvious 'dummies' to hit. It was all white and cream, a dojo of sorts. One wall held various weapons, much like what Lt. Ndrani had done. And since he was used to doing this with no one interrupting him, he didn't think anyone else would come in.
Before he walked out on to the largest mat, he removed his shoes and then walked in bare feet out to the center, paused and then bowed. The next few minutes he warmed up with a series stretches. Then he went into his kata. It started with slow movements and progressively got faster till his hands and feet were a blur of movement. And it ended by progressively slowing down till he stopped right where he began.
