Plenty of gym-goers rely on a good tune to get themselves through that workout, but in South Korea their musical options have just reduced significantly under new COVID-19 rules.

To the standard restrictions such as social distancing and travel curbs, South Korea has added a requirement that gyms do not play music with higher than 120 beats per minute (bpm) during group exercises such as aerobics and spinning.

Health officials say the measure was intended to prevent breathing too fast or splashing sweat to other people while avoiding having to close such businesses entirely, as they have during previous waves.
