Between work, after-hours consultation appointments, TAFE on Tues and Thu nights, I too slacked off for a while. It is certainly hard to get back into it, especially when your lifestyle dictates any time that you have free. Most of my gym work now is in between ads on TV. I get up from the lounge and get on my home gym for a few reps ... and repeat every ad break.
I don't have TAFE now, so I was able to pick up more training time after work.
