WHAT ARE LAP AND SPLIT TIMES?
Lap time is the length of an individual segment of your workout activity. Split time is the time elapsed from the
beginningofyourworkoutthroughthecurrentsegment.
Whenyou“takeasplit”,youhavecompletedtimingonesegment(suchasonelap)oftheworkoutandare
now timing the next segment.
