Research suggests that cardiovascular drift may be associated with dehydration, so make sure that your clients are staying hydrated during their workouts. If you notice that your client’s heart rate is increasing during prolonged exercise, check in with them about their rate of perceived exertion (RPE) and monitor for other signs or symptoms that suggest they should discontinue exercise (i.e. lightheadedness).
