1. how would you determine whether the target heart rate was achieved while walking? what should you do if you felt uncomfortable and out of breath? 2. what are the three components of an effective cardiorespiratory exercise program? 3. what’s the best time of day to exercise?

1. If you maintain a target heart range while walking, you’re exercising aerobically. Walking

at a steady pace, with a little bit of huffing and puffing, indicates that you’re in your target

range. Conversation should be a bit difficult, but not labored. You should feel some exertion,

but your muscles shouldn’t burn and you shouldn’t be gasping for breath. If this is happening, slow your pace and work up to a faster pace.

2. Mode of exercise, frequency, and intensity

3. There’s no one specific time of day that’s best for exercise. Aerobic exercise can be performed at any time of the day, except right after a heavy meal. It’s up to each individual to  determine his or her ideal time to exercise.
