“I’ve noticed more energy! I also noticed my working heart rate has gone down, you see I’m a runner! I run a mile and half in the morning then at night before I go to sleep! My working heart rate should be 158 ! I have finished my runs and my working heart rate has been at 140 maximum! When in the past I would finish my run my maximum working heart would 164 or 168, that’s very dangerous!”
