Right now, I'm killing it. I'm sleeping close to 8 hours, doing well at work, coming home and running/walking, then either cleaning or doing yoga or a strength workout or cooking or baking. Basically if there's stuff that needs doing, I do it, otherwise I'll get in an extra workout.
I'd love to say that it's all discipline, but I'd be a big fat liar. The reality is that there's plenty of external motivation, and a bunch of safeguards. I recently got my Very First Smartphone, and downloaded a cleaning app and a few fitnessy apps that are reminding me to run. I'm using Nike's running app to get in shape for the Warrior Dash, and Fitocracy to help me level up my all-around fitness.
The best part about the apps is that I get pointless internet points, and can compete against others with them. For some reason, knowing that I'm getting beat, even if a person is like, 40 levels ahead of me is making me push myself. Right now, my arms are dead because I wanted to complete a quest. Meaningless Points!!!
My other favorite new fitnessy thing cost money (okay, my cleaning app cost $2 as well). It's a fitbit, and I love it. My favorite thing is the sleep tracker, which I initially thought wasn't a thing I wanted. It not only lets you track your sleep from when you tell the app you went to sleep, but it also uses the wristband to note when you wake up (like when the dog has to go out at 3 a.m.) or when you're restless. I realized that I grossly overestimated how much sleep I was getting, and now I have an alarm set on my fitbit for 9 p.m. Every night at 9 p.m., it vibrates. This is way more discreet than an actual phone alarm, and because I can't figure out how to let it know I am aware of the alarm, it vibrates again in 15 minutes. It's perfect, because the first set of vibrations tell me that I need to wrap up whatever I'm doing, and the second set it like "GO TO BED NOW". It's made waking up at 5:45 more bearable.
