Hey IE, hows it goin?
Do you mean fills strictly on the snare? or just fills across the set?
I don't know about any exercises, but I would recommend changing up the placement of your snare and/or toms.
I just flattened out my snare this week. Before, it was just slightly tilted toward me, but now it is almost completely flat. I wasn't having any problems before, but I love it this way. It is a lot more comfortable.
Are you having trouble because of something like that? or is it just your musclular abilities?
