I'm finding that no matter how much I lift, I never seem to get any real pump or burn in my chest. Is there an optimum grip width to isolate the chest - I know by narrowing the grip you place more emphasis on the tris, but is there too wide a grip? I'm thinking if you go real wide you'd end up putting more emphasis on the shoulders which is not what I want either... I've tried playing with the tempo and that doesn't do anything for me either - I even tried picking a really stupid weight the other day, did a really slow negative and then rolled the bar off - still nothing!
Any tips?
