Speed Bench (Lacking)

Tonight was speed bench presses, or the lack thereof. I seem to be picking a weight that doesn't allow me to work to much on speed/explosiveness. But, when I go lighter, it never seems enough to benefit all that much. Changes will be made accordingly next speed bench session.
