USING THE HEART RATE ZONE TO MAXIMIZE WORKOUT BENEFITS

Research shows that keeping the heart rate within a certain range while exercising promotes muscular and cardiovascular conditioning for maximum health benefits. This range is between 60 percent and 85 percent of a given user’s theoretical maximum heart rate. The maximum rate varies by age. To calculate it, subtract the user’s age from the number 220.

For example, the theoretical maximum heart rate for a 35-year-old user would be 185 beats per minute (bpm) because 220-35=185. Therefore, the optimal heart rate range or zone for a 35-year-old user would be between 111 bpm

(185 x .60) and 157 bpm (185 x .85).

NOTE: Consulting a fitness trainer is recommended for defining specific fitness goals and designing a workout program.

To monitor the heart rate during a workout, feel the pulse in the wrist or the carotid artery in the neck while looking at a watch. Count the number of pulse beats within one minute.

SWITCHING THE CONSOLE DISPLAY TO METRIC UNITS

By default, the bike’s console displays the workout statistic of distance in English units. It is possible to switch to metric units. When the console is shut down, remove the four screws that attach the console to the console support assembly column. Carefully turn the console upside down and flip the “English/Metric” switch that appears in the back of the con- sole to the “Metric” setting. Re-attach the console to the support assembly column. Restart the bike.

3.3WORKOUT DESCRIPTIONS

INTERVAL

This workout combines “hills” and “valleys” of alternating high- and low-resistance levels. Raising and decreasing the heart rate in this manner is proven to provide effective, time-efficient fitness results. Each interval is of equal duration, and the overall duration of the workout determines the duration of the intervals. As the profile diagram indicates, the workout begins with a low-resistance warm-up and ends with a low-resistance cool-down.

RANDOM

When the user selects a RANDOM workout, the bike computer automatically generates various profiles, each offering a different combination of resistance levels. This choice of profiles adds variety to the workout routine.
