reading on the treadmill?

hi guys! i’m trying to get myself back into the gym. all i’m currently doing is cardio (treadmill mostly, but often elliptical and stair master).

last week, i saw someone at my pf reading a book while on the treadmill. does anyone else do this? i love reading and maybe it’ll help me get there, but i don’t want to potentially get kicked out

side note: i do love audiobooks, but my attention span is so short that i’ll get bored and want to stop😅 i think a physical book would help that
