Ha! Fitness, yes. The thing I do because being fat and the thought of gaining weight is absolutely nightmareish to me. Also, healthiness is good.
It was difficult for me to do in the past. Due to he fact that mustering motivation to drive out there into the actual world, to the gym or to ride a bike in a street full of cars... well, that was hard. I like to just stay in my room all day. BUT! I figured out a way so I don't have to go anywhere at all! And still stay fit.
I play Wi-Fit everyday, religiously. I mostly just use it to run in place and measure my miles, as that is the most intensive exercise. (I do that for around 30 to 40 minutes, five days a week.) I also measure my weight everyday. (Speaking of which, it is getting late and I should do that right now) And I watch what I eat. I don't really eat junk food very much, as whilst it takes good for a second, my brain makes me feel so painfully guilty that the taste is immediately supplanted by immense mental distress and pain. It's really really bad. I snack on wheat thins and dried fruit (actually really filling, and tastes loads better than it sounds), and pretty much just live on that, cereal, and some rice/meat bowl I make real quick. Also, I eat low calorie foods off of a gas station's menu a lot too, as we like to go out due to the fact that we get bored of eating the same thing becaus I'm not really into cooking right now. (It's not a regular gas station though. Their food is one of their main focuses and is really high-quality. Resturant-like stuff. It takes them a while to make.)
