Guidelines for Safe Exercise
Frequency - 3 to 5 times a week
Duration - 20 to 60 minutes
Intensity (how hard) - within your target heart rate
Calculating Your Target Heart Rate
1) 220 - age = MHR (maximum heart rate)
2) MHR x 0.6 = _____ (this is the low end of your target HR)
3) MHR x 0.8 = _____ (this is the upper end of your target HR)
Example:
180 x 0.6 = 108
180 x 0.8 = 144
Therefore, your Target Heart Rate is between 108 and 144 beats per minute.If you are 40 years old, your MHR is 220 - 40 = 180.
