[b]Aerobic exercise works very well in AM before breakfast,then you eat 1 hour later.[/b]
[b]Resistance training(weights) works best ---for most people---in the afternoon/early evening.[/b](increased metabolic state,etc)
Working out before sleeping is NOT a good idea because your body will be in a state of "excitement" with adrenalin levels among other things running high!The result being that, you will not be sleepy for 3-4 hrs after that.
[b]So how do you work around your schedule?[/b]
Ideally,you would come home feeling rested and energetic enough to do your aerobics,shower,eat breakfast an hour after your aerobics,play/talk to the family for 1-2 hours and get some well deserved sleep ....after the exitement wears off!
You could then wake up and work out with weights,eat a high protein/moderate carb dinner and rest before going to work again.
Unfortunatelly,unless you work for a mattress company as a tester... and sleep on the job,you will not get the needed sleep that will let you recover from a good workout(elevated GH,etc).
Well, nobody has a perfect schedule,and you have one a lot less than perfect.
I imagine you come home tired from a night of work and don't care to do 30-45 minutes of aerobics at the time!
You just got to make the best of what you have.
If you can do what is recommended above,great!If not,do something when you get up!
