Hey guys

I'm going to be learning some ju-jistu in the near future, and am thinking about doing some wrestling as well... problem is, I won't have much time to train with work and family and the nearest wrestling room 45 minutes away.

What kind of workouts can I do (weights, cardio ect) that will at least sort-of simulate wrestling or grappling so I can do those things occasionally without being rediculously out of shape?
