Advice to become a CRNA or NP

Hello! I am currently in school finishing up my bachelor's in Exercise Physiology. I wanted to go to PT school but realized the odds were not in my favor. So, I will be applying to an accelerated BSN program this winter. I know of the advanced career paths of nursing but two that really interest me are CRNA and NP. Any advice to prepare for either field? Are there any current CRNA and NP's that can describe their experiences or weigh out the pros and cons?

Thanks!
