I have a few issues with the bench I'm using for bench pressing. It's an adjustable bench and as such, it is less than rigid. No matter how many wedges I put in place, there's always some side-to-side rocking. It also has a pretty thick slab of padding on it (a full 2". I dislike squatting in trainers compared to hard-soled, Oly shoes because of stability and drive issues. So, should I be using a bench which is very stable and with very little padding for the same reasons? I'd like to know roughly how thick the padding is on the bench that you generally use for bench pressing and whether you like it or not? Should I get a new fixed flat bench? If so, any recommendations?
