Excercise while experiencing GERD (Gastroesophageal reflux)

[kray]

Been having GERD for the past three days. Quite literally a living hell. Worst part is that I can't even get my exercise routine in. I tried going for a run the other day, towards the end I experienced a pretty severe acid reflux. For those who've been in my position, are there any exercises I can do that don't trigger my acid reflux/heart burn so severely?
