Each HILL workout goes through four phases, each marked by different intensity levels. The WORKOUT PROFILE window displays the progress of these phases, as seen in the chart following these descriptions below. The heart rate should be measured at two stages in the workout to gauge its effectiveness. To do so, wear the chest strap. Note that the MESSAGE CENTER does not dis- play a request for a heart rate measurement during a HILL workout.

1Warm-upis a phase of low, gradually rising resistance, which brings the heart rate into the lower end of the target zone* and increases respiration and blood flow to working muscles.

2Plateau increases the intensity slightly, and keeps it steady, to bring the heart rate to the low end of the target zone. Check the heart rate at the end of this phase.

3Interval Training is a series of increasingly steeper hills alternating with valleys, or stints of recovery. The heart rate should rise to the high end of the target zone. Check the heart rate at the end of this phase.

4Cool-downis a low-intensity phase that allows the body to begin removing lactic acid and other exercise by-products, which build up in muscles and contribute to soreness.

Each column, as seen in the WORKOUT PROFILE WINDOW and the chart above, represents one interval. The overall duration of the workout determines the length of each interval. Each workout is made up of 20 intervals, so the duration of each interval is equal to the duration of the entire workout divided by 20.

10 to 19 minutes: The interval durations initially are set at 30 seconds for a six-minute workout. For every minute added by the user “on the fly,” each interval increases by three seconds. A 15-minute workout consists of 20 intervals at 45 seconds each.

20 to 99 minutes: All intervals last 60 seconds. If the user adds minutes to the pre-set duration while the workout is in progress, the workout adds hills and valleys that are identical to the first eight intervals of the Interval Training phase. This pattern repeats until the workout is completed.

RANDOM

The RANDOM workout creates a terrain of hills and valleys that varies with each workout. More than one million different patterns are possible.
