Exercise physiology pre Med questions

I never relay considered the U until I went yesterday and loved it. I was doing research and it seems that a lot of people are pre Med, which can make it very competitive. If I were to attend, I think the exercise physiology major is really interesting, and you can follow the specific pre med track. However, if I were to attend, could I just do the pre med requirements separately so I don’t have to take certain classes? For example, I could take different chem(principles of chemistry vs chemistry for the life sciences) and physics(college vs university) classes as well as skipping a biochemistry class made for pre meds that is most likely very competitive. I would still take the pre med requirements just outside of the specific track. I guess my question reigns is there a reason I shouldn’t or wouldn’t be allowed to do this? Any insight would be greatly appreciated! Thanks
