Here's a simple tip that may or may not have been mentioned (and maybe you already use it, to no help) - Work out with an ipod. I LOVE hitting the gym when i can blast my motivating music. It is nearly impossible to push through a workout without that there, though.
Also, if you're doing cardio, straight cardio is mindless and dull. I prefer high intensity interval training for several reasons. 1) it's better at burning fat than straight cardio and will also burn less muscle that steady rate cardio, and 2) because you are constantly having to remain aware of your time, changing pace, and so on, it's less monotonous and dull.
HIIT is something like this - I have bad knees, so I can't do it on the treadmill anymore...I use those machines (I can't think of the name now) that run on a track but you can adjust incline and resistance. So I warm up for ten minutes. The I do 8 cycles like this - 30 seconds at 10 incline and 10 resistance going as hard as I can, 1 minute at 6 incline 4 resistance. Repeat 8 times, cool down, and you're done. The idea is to have short bursts of MAX intensity followed by a slightly longer stretch of moderate intensity (1:2 or 1:3 ratio). It will kick your butt so hard that you won't have time to get bored.
