My girlfriend wanted Wii-Fit so I picked up a copy when it came out. I like it a lot more than I thought I would.
About five years ago, I was about 220 pounds. I was never fat growing up but after graduation and entering the working world, I was no longer a healthy medium build. I decided to start eating healthy (not easy since I worked for a vending company and was thus surrounded by 20 types of chips and 40 types of candy and chocolates and 30 types of coffee/soft drinks as well as a freezer full of crappy microwaveable burritos, pizzas, and sandwiches as well as about 10 different types of ice-cream). Basically I put myself on a 1600 or so calorie a day diet (no roll-over) and started doing some light exercise. It also helped that I lived near a small mountain so light exercise consisted of walking up that mountain and my job was in a warehouse in the desert--I really just needed to have a not horrible diet to lose weight.
Three months later, I was down to 180 and feeling pretty good about it but I still wanted to get down 165 pounds. This wasn't easy. I ended up quitting my job, which was basically a work out routine five days a week, to go back to school. I didn't have time and all other excuses not to exercise... but I kept a routine of eating healthy and was able to maintain my weight loss. And then I got Wii Fit.
First weigh in was 172 lbs. Shit, I'm doing okay with this weight loss thing. Well, lets set that goal to 165 and away I go. I'm not saying that Wii Fit is a good exercise routine. What it does do is put your weight in front of you and it also shows where you want to be. I definitely credit it for helping me keep an interest in my body health--something I never really took a lot of notice of--they yoga and mini-games and what not are a bonus. If the goal of Wii Fit is to give you a few reasons to get you on a scale every couple of days, its a success on that front. I can't say if it's good or bad as the only factor in an exercise routine since I've never wanted or needed to use it as such.
This is my 534th day and I'm 150 lbs.
