Deciding on a major

Hi! I’m a senior in highschool applying to college this year and want to be pre-med!! I’ve really been debating my major since I don’t want to do bio/biochemistry or public health as I feel it wouldn’t give me a lot of backups in case I need a fallback for medicine. Any thoughts on exercise science as a major? I would love to be a sports med doc/physiatrist when I’m older and find all the subjects I’d be studying for exercise science SO interesting and feel like I’d be happy falling back on pt/ot if med school doesn’t work out. Will majoring in this put me behind in any way or if I get the pre recs all done does it even matter?
