Personal training out of the question for you? If it's not, I'd highly suggest it. You'll get the most out of each time you go to the gym.
If you're not comfy with that then you could always just buy some equipment yourself. We have those large aerobics balls, the elastic straps, dumbells, and a few mats. That's all you need and sometimes it's nice to just stay at home and workout.
Btw, if you can, SWIM! That's probably one of the best ways to work out. Works every muscle of the body.

Sig pic unrelated. I like to go sideways and stuff.
