Well, i did bodypump session with mask on, surprisingly it was okay (maybe because not cardio based). Mask is only required during class, but those using gym floor do not have mask on. I will recommend not to use cloth mask as it can be suffocating, and get a mask guard (probably $1 or less on lazada or shopee website).
Check with my PT, for PT session mask is not required too.
