Title: This has saved my life!
Review: I have exercised off and on for years, but then had to stop for awhile after surgery. Starting back, I got this, and always wear it to the gym. It not only lets me know when I'm about to over do it, but I can see if there is any arrhythmia, a sign I am already overdoing. It has taken a little practice for me to learn what is the right amount of exercise for my body, but it has been very helpful! It's great not to have to stop working to take one's pulse.It isn't possible for my husband to use, however, as he has had rickets, and the chest monitor won't pick up the impulses. I wish there were a wrist-only band to check the pulse.
