Are You a High Responder or Low Responder to Aerobic Exercise?
Not everyone responds the same to exercise. Some people see visible results faster than others. People who have more of an ectomorphic body type have to work harder and take in more calories to build muscle. On the other hand, mesomorphs gain muscle definition quickly. What about endurance exercise? Just as there are differences in how quickly people can build lean body mass, there are variations in individual responses to cardiovascular exercise.
