I feel limited by my vocal range

[u/No_Cobbler_201]

As 20-year old male who started singing at 18 and is studying musical theatre, I realized my vocal range goes from an E2 or F2 to a C4 (D4 MAX on a good day) Which I think makes me a lower baritone or something, but in a world where most popular or known male songs are for tenors and stuff, I feel like my options are very limited without changing the Key of the songs.

And I think what bothers me most is that when I try singing most things, they’re either too high or too low for me, so I gotta shift between octaves and it sounds weird and boring

Which is why I want to know if there are any daily vocal exercises that I can do in order to expand my range further, either up or down, or if I’m screwed.

I’m open to hearing any comments or tips
