I understand the intent, but if it's too risky to be in a gym with people working out in sync with 120bpm, then my personal risk assessment would say it's too risky to be in the gym, period. I wouldn't feel any better just because the music was 90bpm. Edit: Then again, humans are notoriously bad at evaluating risk, so I may be way off base. :-)

FWIW, I went for a heart checkup at the hospital recently. They were doing ECGs as normal, but they weren't doing ECGs-while-exercising due to covid risk. I think the difference between regular breathing and hard breathing due to intense exercise may be significant.

My personal take on gyms would be that well ventilated ones are likely quite safe, but the most are probably not sufficiently well ventilated.

If anything I'd expect gyms to be better ventilated than offices or supermarkets. I'd imagine smelling of stale body odour isn't a great selling point for most gyms (maybe the more hardcore gyms it is?), and there's no way they are going to keep that out without decent ventilation.

My gym is in a converted warehouse. Probably 30' ceiling at least, so it's mostly open air. Lots of fans and HVAC so the air is constantly moving. It was closed from March - June of 2020. Reopened in late June with masking and social distancing as per local rules. There was an exception to the masking rule "while exercising" so basically nobody wore a mask in the gym. I returned to my every other day habit, my workout takes about 90 minutes and then I sit in the sauna for 20 minutes and then shower.

I'm not aware of any local cases linked specifically to gyms, so it seemed to work out fine.

I certainly wouldn't be at all surprised if gyms ended up being safer than offices and supermarkets. Offices in particular (where one typically spends hours in the same room) seem pretty unsafe to me.
