Just so we are clear--
This 'feel' is done on the flat bench--NOT the decline. I don't like the decline. You simply 'feel' the weight moving towards your toes as opposed to arcing it over your head and shoulders.
This activates the areas of the chest same as decline with less shoulder irritation-if you are so inclined. Some people have no issues. Do whatever you want as long as you have no medical issues with it.
How can you do a decline and push the weight to your toes anyways? Didn't it fall on your nuts?
And again, I emphasize, it is a feel, much like the feel of tearing the bar apart or feeling like you are trying to touch your hands together to induce tension on the pecs. You aren't actually pushing the weight over your toes.
