Comment Self defeating (Score 3, Insightful) 865
I realize that you have a relatively insane schedule, but go back and read your comments. They are nearly all self defeating. Working out regularly is like quitting smoking - it's something YOU have to want to do for yourself and your own benefit. You'd be amazed what a simple set of adjustable dumbbells and a weight bench will do when used for only 20 minutes a day 3 to 4 days per week. Throw in some form of cardio on your days off from lifting, and you're doing far better than most of the general public.
Also, if you are truly serious about staying in shape, take a good look at your diet. Years ago I switched my diet from overly processed starches and red meats to include more whole grains, skim milk, water, whole fruits and vegetables, and green tea. My energy levels easily doubled. The amount of time I spent sick dropped.
Seriously, if you truly want to get in shape, you will make time for it. All it takes is making it a habit, which will probably require a 2 month investment on your part, whether you feel like it on a given day or not. There are days when I don't feel 100% like working out, but once I get about 5 minutes into my routine, I am up to the challenge.
