Do you have any personal trainers at your facility? Sometimes it's the best way to get a routine going and staying focused. Let's face it, Exercise rooms are BORING. Mine is loaded up with TV's, the stereo is on, and folks are reading, listening to music, etc. while working out.
Going at it solo is very, very hard unless you are committed and disciplined. It's even harder as you get older or you've never had a workout program before. A double wammy!
I'm really impressed that you not only have the motivation to go into the gym, but your are sticking to it, trying new things, and even posting about it. I highly recommend you find a partner or better yet, get a good personal trainer to get you kicked off right.
Have a great weekend as well and keep us posted on your progress!
