As you become more used to exercising and the Sweat Suit, try to keep your heart rate at about 60 to 85% of your "maximum heart rate".
To figure out your target heart rate
Subtract your age in years from 220 (which gives your maximum heart rate)
Then multiply that number by 0.60 or 0.85.
For example, if you are 40 years old, you would subtract 40 from 220, which would give you 180 (220 - 40=180). Then you would multiply this number by either 0.60 or 0.85, which would give you 108 or 153 (180 x 0.60=108 and 180 x 0.85=153)
When you first start your exercise program, you may want to use the lower number (0.60) to calculate your target heart rate. Then, as your conditioning gradually increases, you may want to use the higher number (0.85) to calculate your target heart rate.
Check your pulse by gently resting 2 fingers on the side of your neck and counting the beats for 1 minute. Use a watch with a second hand to time the minute.
