Hello all, I finally had and past my dive medical on friday. I am told the next step is PRNC, I was told that I'm gonna be really put out of my comfort zone (not that I mind that!). I am basically asking what does the PRNC entail for potential MCD's? Obviously the runs will have to be quicker... but swimming, push ups, sit ups etc? Just want to know what I'm in for so I can train accordingly. Recovering from a small case of runners knee from an ill profiled pair of running shoes! Many thanks!
