2 cardio sessions a day?

I am currently working on my last 15 pounds to get to my 2009 weight goal of 200 pounds (almost 40 pounds down this year w/ another 30 pounds to get to a normal range BMI sometime in 2009).  I have done this thanks to cardio at night before I go to bed and trying to keep my diet under control.  I was thinking about doing 2 sessions of cardio a day, but I hardly ever get up on time.  I was wondering if it was safe to do some lighter cardio at 6 (when I get home from work and would be a new wrinkle in my fitness regimen), light to moderate weight training every 2 to 3 days at around 8 (something I am already doing), and my normal full session at 10:30 (just before I go to bed, and again, something I am already doing).  

I am still trying out different methods to motivate me to get my butt out of bed, and the extra cardio session in the morning would be best, but I was wondering if I am pushing my body to add the extra cardio session.  

Hey you! I hope that someone will answer this question too as I am facing the same problem... I work in the nightlife, so when I get up around 1pm, I'd get out for a run, and then around 4pm, another running/walking session. Not sure if it's pushing it too far (I am doing at least an hour a day).

I eat around 1,400-1,700 calories a day. Should I rest my legs for a day, or just continue running daily? (I just don't wanna break the habit now that I am all pumped up..)

It's not unthinkable, but I don't know that it is beneficial. At some point (rather quickly) you are going to reach a point where you start to get stale and the quality of your workouts will start to suffer. Not to mention the increased risk of overtraining and injury. It's one thing to add more casual or recreational activity (e.g. riding a bike or walking for small errands instead of driving), but at a certain point, quality of exercise is better than just increasing quantity.

Mm.... I do 2 a day workouts, bringing me up to 2.5-4 hours workouts (total) a day. *I* don't have a problem with it, but be prepared to be ravenous, and I mean RAVENOUS.

Make sure to build up slowly- start with one day a week with 2 a days, and then build up, right now I'm at 5 2-a-days, 1 *one* practice, and 1 rest day. I intend to stay there too. And I wouldn't make it all running/pure cardio. Weights, swimming, biking, are all good 2nd workouts. (ie- on days I do my long runs- which are EXHAUSTING- I ONLY do a long run that day, other days with shorter runs I swim or bike, or I do two swim sessions, 1 bike 1 run session)

For a long period in my life I did both swimming and one extra sport each day. Some days it was squash, others it was martial arts or rugby. These days I don't exercise that often any more. The biggest benefit will come from cross training. Use other forms of training so that you don't over train certain muscles. Most importantly, listen to your body. It needs sufficient rest and constantly exercising will reduce muscle mass.
