Thanks to all of you for your thoughts on this. I appreciate the information.
I agree that it seems like the trainers at LifeTime are required to focus on sales as much as training. However, I probably need to increase the intensity of my workouts. At least this whole experience has jump started me to take a look at this and start kicking into a higher level. StuWard, thanks for the Web site information and Depalma, you're right- I am sure my body adapted to what I've been doing.
Best,
Anne
