USING THE RECOVERY TIMER
Heart rate recovery is the difference between your heart rate when working out and your heart rate after a
short rest period. A larger difference between your workout heart rate and your heart rate after the rest period
indicates quick recovery and therefore better conditioning.
The recovery timer measures this difference and reports the result in a popup to help you gauge your
cardiovascular health.
When turned on, the recovery timer will activate when you stop or pause the chronograph while the heart rate
sensor is collecting data.

TRAINING WITH INTERVALS
BENEFITS OF INTERVAL TRAINING
Interval workouts are powerful tools that let you target and train for specific qualities (like speed, endurance,
or threshold). Interval mode helps keep track of times or distances for up to six intervals and 99 repetitions.
Intense periods of activity interspersed with recovery periods of lesser activity help you train more intensely
and for longer periods. Combining aerobic and anaerobic activity in this way helps you:
You should set up interval workouts to train for a specific quality. Two examples are described here, but you
can create interval workouts to train for virtually any quality using the six intervals and 99 repetitions.
exampLe of enduranCe workout
To train for endurance, you might set up a classic 1-mile repeat workout: 3 to 6 repetitions of one 1-mile
interval at about half-marathon pace, followed by a 1-minute recovery period.
exampLe of speed workout
To train for speed, you might run sets of 4 x 400m: run one 400m fast interval at slightly more than your race
pace, followed by one 2-minute recovery period, and repeat 4 times.
