Wouldn't board presses be kinda the same as floor presses? I still have never done either one but it sounds like they would work the same. What part of the bench do board presses help anyway?
floor presses you feel the weight transfer more through your arms and by laying on the ground you also take your legs out of the move so it becomes even more of an ass whoopin for the upper body.when you do your board presses you feel the weight transfer through the boards into your chest,then as you press you can use leg drive(unlike floor press).
