I'll second everything said here. "The gym doesn't count" is an utter lie. If you've led a multiple-year sedentary lifestyle, a mere 15 minutes on a treadmill in the morning will show you an immediate difference in your motivation and mental clarity.
Also, fat-asses: you don't have to kill yourself at the gym. Look up on the internet what your target heart rate should be, and stick to it. If you feel like you're going to fall over and die, you're making it too hard on yourself.
If you're just getting started, developing the habit of going regularly (at least 3x/week) is immensely more important than minutes ran, reps, or pounds lifted.
It's incredibly hard to start and stick to a routine if you're not used to it. I've only done it three times in my life, but it paid off every time. And the years in between were racked with life-altering depression and failure.
