Although we cancelled the wedding that was planned for last weekend, we have been talking about combining households next summer and are going to embark on a lower level renovation project this winter to get ready. I moved into the current house a little over two years ago and the lower level is completely unfinished. The plan is to put in a large media/entertainment area, a smallish full bath, one large bedroom with a walk-in closet and a gym that will house all of the current equipment and possibly a new acquisition. The area will be quite large - probably about 13' x 20'. I already have a body solid squat rack with upper and lower pully and incline decline bench, a good treadmill, a livestrong elliptical trainer, and free weights. My fiance has a fitness allowance through work and we are thinking to use it to add something for the gym. After we consolidate houses, his 15 and 20 year old daughters will likely be using the gym as well.

We were thinking to add a rowing machine but I'm not sure another piece of cardio equipment will add a lot of extra function. I was thinking maybe kettleballs but other than that, we are drawing a blank.

Do you have a favorite piece of gym equipment? Or thoughts on something that could add to our set-up?
