Query: I had no idea I am an elite athlete! (cough cough)

This is probably the monitor the President used to determine his heart rate is that of an elite athlete because I can't seem to record more than 35 bpm (in spite of having a resting pulse of around 60). Well, except for the time it told me my resting heart rate was 135. I tried applying vaseline as others have mentioned but still can't seem to get an accurate reading. Recommendation for the manual says to make sure the strap is snug but it has to be uncomfortably snug for me to get a reading at all. I've tried all sorts of tricks and re-read the manual several times but appear left with a bulky (thick) digital watch.
