Is there a Minimum number of Personal Training Sessions I have to purchase?
No.  You may purchase personal training one session at a time.   Some clients prefer to utilize training as a once in a while change/shock to their normal training routine.  But...Of course as you purchase more sessions in bulk, the price per session goes down.

I have been working out for over a year with no measurable results.  What should I do?
We'll be happy to review your routine and diet and happy to make a recommendation.   It is usually very easy to spot the problem areas in an individuals fitness/nutrition regimen.  The initial consultation is free.
