DCI and DCS are not synonymous, Rich. DCI = DCS and/or AGE (arterial gas embolism). Thanks for bringing this up as it is a common source of confusion, even among the nitpickers. And exercise before diving is not recommended either, but doesn't carry as high a risk as exercise before or shortly after diving. Actually, this exercise thing bothers me a little, because I love to dive, and I often exercise, but the two are not highly compatible (as long as you dive with nitrogen in your breathing mixture).
