The acronym means “every minute on the minute.” You essentially set a timer to do two exercises, Romero says. They are, for example, 5 burpees and 10 pushups. Set a timer for a minute. “If you are done in 35 seconds, then you have 25 seconds to rest and start over.” If you are done in 50 seconds, then you only have 10 seconds to rest before you start again. “The faster you go the better because you rest for longer,” she adds.
