Q:What are METs, which are listed on the monitors of some cardio machines at gyms?
A:METs, short for metabolic equivalents of task, are a measure of the intensity of physical activity. One MET is the equivalent of resting metabolic rate—the rate at which the average person burns calories when at rest. At 2 METs, you’re working at twice your resting metabolic rate. In general, 3 to 6 METs is considered moderate exercise, depending on your age.
Activities with METs higher than 6 include singles tennis, jogging, cycling (more than 10 miles per hour) and cross-country skiing.
