I can attest to the pre-dive workouts.  I sprained my shoulder playing softball
the night before diving wrecks off of North Carolina.  We did a little deco and
were well within acceptable tables, and I took a minor but painful hit to that
same shoulder.  Symptoms resolved by the next day.  I can't say much about
exercise itself, but I'm sure the
injury is what made that hit possible.

(e.g. complement system) may be triggered and respond more vigorously to
bubbles, but this is even more uncertain. The best advice is to avoid diving
while you're suffering from minor athletic injuries.

bubbling in supersaturated tissues. My educated guess is that this would be
relevant up to a few hours after a dive only. Micro-bubbles tend to peak after
30 min to 1.5 hours. If you avoid work-outs within this time frame + a safety
margin you'll be past the critical period.

any pain to the work-out, which may or may not be true.
