crystal,
I'd forget those health club numbers completely. They are measuring your body under the probably highest stress state of your whole day.
Buy a cheap home BP unit and use it for several days when at rest in front of the TV. (You can always return it for zero cost but I'll bet you keep it.

)
If you get nearly consistent readings below 140/90, don't give BP another thought. If, however, you are consistently higher mention it to your MD on your next visit (earlier if you get anything like 160/100 at rest.) Doctor will invariably start you on one of a zillion drugs if he finds HBP. A sensible start is cheap hydrochlorothiazide diuretics.
Don't panic. You'll merely be joining most of the rest of the adult population.
