Not for a person already in semi-decent shape
Customer Rating: 
I was SO excited to get the Wii fit and have something to do indoors when the weather's not nice. I thought it would be something to teach me better balance and get more exercise and be like a fun, addicting game. I was hoping the fitness part would be as addicting as a video game - but exercising while I played! Not at all.
It's like going to a gym for 80-year-old people. You NEVER get your heart rate up. After every single exercise, regardless of how short it is, there's a long wait while you select more stuff and hear stupid reviews about how well or poorly you did. Every single time you go down the ski hill you have to listen to the music, watch the stupid character dance or mourn depending on his score, wait for the stupid machine to tell you you're "out of balance" and keep pushing "A" and wanting to scream out of frustration. There are constant breaks in the boxing, too. The hula hoop would be OK if you got to do it for longer without stopping.
It's also very naggy. It's like having a teacher micromanaging your every move, constantly making you stop and giving you "constructive criticism" rather than letting you try again and again until you get it right. I don't need somebody telling me how well I did - I can see my score.
I HATE it. When you add up the cost of the Wii itself, then the extra controllers, the Wii Fit - I spent $600.00 for a stupid machine that's good for nothing but playing Sims Castaway. We already own a PlayStation - and Dance Dance Revolution is a MUCH better workout anyway. I'm going to the video store to rent Rhythm Kung Fu. If it's not a decent workout, I'm selling the d&*) thing on E-bay. I haven't been this angry in a long, long time. That (...) could have gone to buy new cycling shoes and a TON of outdoor fitness gear.
Oh - and by the way - I'm a slightly overweight 40-year-old woman in only semi-decent shape.
Come on, Nintendo! If you want to give people a REAL workout, make an addictive game out of it. Make it like playing a martial arts based video game where you run around mazes punching and kicking people or something - something you could play for hours and only want to stop when you're so exhausted you physically can't do it anymore. This is totally lame.
