I'll tell you what I do, and it works for me

I run for 15-30 minutes (depending on the day I've had). I have to tell you though, I worked up to this! I started running as long as I could, then walking until I got my breath back, then run again, walk..run... walk... Don't expect to be able to run right at first and don't give up! You'll work your way up to longer and longer periods!
After that, I usually do either the eliptical or recumbant bike for another 10-15 minutes, really pushing myself (depending on how long I ran).
I then go and do a shortened (ashtanga/power) yoga routine (about 20-40minutes) so that my muscles elongate and I use my own weight as resistance. You dont' really need more than your own body weight as resistance - you just might need to take a few classes and learn a bit of a yoga routine.

In total, I am usually at the gym for about 1hour although some days I might be there upto 1 hours and a half (depends on what I need to do that night).

Just whatever you decide to do, don't give up! It's really hard at first to get into anything physical after not being physical but then it gets to be such a part of your life and your body craves it! I love working out now! These days I go about 3 times a week and do a full ashtanga yoga routine on the other days!

Cheers
