I'd do some speed work... and this might be something you throw in on your leg day and more core work to your pull day... it all depends on your recoverability. But assuming you are training for athletic prep, speed work is excellent. You can do things with ladders or cones. Shuttle runs, jumps and bounds, etc.
Or doing stuff with unusual objects, like woody bags for example. Especially if we're talking about wrestling and grappling.

Bottomline is your training should be very specific for what you're trying to accomplish 'on the field.'
And sometimes trying to improve everything all at once is counter-productive. If this is what you find to be the case, I think you should start focusing on improving one or two qualities and moving everything else to maintenance. Then you cycle through each of the qualities in a rotational basis.
