Gyms in and around South Korea's capital Seoul have a limit on what music they can play. The government set a maximum speed on songs to limit the spread of Covid-19. There could be a new coronavirus wave in South Korea. The new rules are to stop people breathing too quickly or splashing sweat on each other. Gyms cannot play music with a tempo higher than 120 beats per minute (bpm). The song Bad Romance by Lady Gaga is just under the limit at 119 bpm. K-pop fans will be happy to know they can work out to BTS. The BTS hit Dynamite is around 115 bpm.

South Korea's Prime Minister warned that the country had reached "maximum crisis level". President Moon Jae-in said he felt sorry for businesses affected by the rules. He asked people to have "a little more patience". Many gym owners are unhappy with the new rules. One said: "My biggest question is whether playing classical music or songs by BTS has had any impact on spreading the virus." He asked: "Many people use their own earphones these days, so how do you control their playlists?" Another new rule is for treadmills. They will have a maximum speed of 6kph.
