This used to be my gym and perhaps some day when my hectic work schedule chills out, it will be again. At one of my jobs, a gym membership at Totum was part of the job benefit package (doesn't get much better than that - except perhaps dental). The staff gave me a gym orientation, showing me around all the equipment (including giving me advice on what kind of workout I should do to reach my goals), and explained the benefits of the other services they offer (like massages, yay!).
I quickly realized that working out in the wee hours of the morning before work is where it's at. I recommend signing up for the 6 am and 7 am classes. Attendance is (or at any rate used to be) minimal which means you get a lot of one-on-one attention from the trainers. Several times this meant I got a free personal training session. Chill out afterwards in the steam room to get rid of all those pesky toxins out of your system and then use the outstanding change-rooms to get ready for work. They even have extra toiletries in case you forgot anything at home.
Definitely worth the extra money for a membership!
