Suunto t3d manual Using intervals and warm-up

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.

4.7 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.

Setting	Value	Description
