 TIP: If your heart rate varies significantly during training, for example, when running
in hilly terrain, following your real-time average heart rate is better guidance than following
zone limits.
4.6  Using intervals and warm-up
Your Suunto heart rate monitor supports interval training, training with alternating
periods of high exertion and recovery. Use 
INT1
INT2
 to define different interval durations.
You can also define a warm-up period for yourself. This can be used with or without
intervals turned on.
When you use the intervals and warm-up, the log recorder view option in 
TRAINING
mode becomes a countdown timer. Use this view to follow how much time is remaining
for your current interval. Once you have started the training session, the countdown
timer resets itself as each interval passes.
When you are training with intervals, 
INT1
INT2
 or 
WARM
 is shown before the countdown
time to tell you which interval you are on. The lap indicator on the screen tell you how
many intervals in total you have done, for example, int1 (lap1), int2 (lap2), int1 (lap3),
int2 (lap4) and so on.
