In terms of frequency, you should try and exercise at least three times per week.
The intensity of each workout refers to how hard you feel your working and can be measured
by your heart rate. Depending on your fitness goals, exercise between 55% and 90% of your
maximum heart rate. A simple way of estimating your maximum heart rate is by subtracting
your age from 220. As a general rule of thumb, if your fitness objective is to Lose Weight, you
will want to keep your heart rate between 60% and 75% of your maximum heart rate. If your
objective is improved aerobic performance keep your heart rate between 75% and 85% of
your maximum heart rate.
To achieve benefits from your workout, your workout time should be at least 20 minutes per
session. If you are trying to lose weight focus on longer (more than 30 minutes) less intense
workouts, to improve your aerobic performance focus on shorter more intense workouts.
As a rule of thumb when your exercising, if your having trouble completing a sentence, you are
working too hard. When exercising, you should be able to speak freely without gasping for air.
