A relatively unfit worker with resting heart rate of 80 beats/min starts his job of palletizing boxes. At the morning break, an industrial engineer quickly measures the worker's heart rate and finds a peak value of 110 beats/min one minute after stopping work and a value of 95 beats/min three minutes after stopping work. What can you conclude about the work load for this worker?
