Training Room for FC

Hello, and this probably falls under this forum the best.

I've decided to remake our FC's training room within the private room section of the house since the person who had made our last one left.

I'm looking for suggestions on what to place. While they had done a good job, I'd like to not make the exact same room, though I will be doing the Tatami Flooring at least, and being a Maelstrom Themed house, I'll be using that Wallpaper too. What would other good pieces of furniture work well for a training room?
