Nikon L120 setting advice in gym?

I have a feeling that I'm out of luck on this. Normally this is a great little camera and takes awesome shots just on auto settings. However, I tried every preprogrammed setting I could and still ended up with grainy shots. They don't need to be action shots, although some of the better shots came out under the action/sports setting. Obviously I'm not a photographer… just trying to get some decent pics of my kids. Also a "good" camera is a bit out of the budget. Any suggestions to improve the quality? Again… not looking for professional shots here, but what I ended up with looks like I took it with a 1980s 110 camera.
