In short, I am in my mid twenties and work at a bank, so I spend a lot of my time sitting.  The last few years has seen me put on some weight, and as of my last physical, my blood chemistry--mainly my triglycerides--was a little too high and my High-Density lipoprotein--HDL or the "Good Cholesterol--was too low.  I was not fat by any means, but was a little overweight (6'1" and 215 lbs)

I live in Northern Alberta (that's in Canada for those of you that do not know), and thus, this time of year it is hard to be active outside, considering its pretty cold this time of year.  Combining better eating habits, and Wii Fit, for which I finally found in January, has led me to losing over 30 pounds.

Say what you will about Wii Fit, but for me, I find its a great way to keep me motivated to work out, especially in Winter.

On a seperate note, my wife got me House of the Dead Overkill for my birthday last week.  All I can say is this game is fantastic, and I think it takes the HOTD series in a much needed new direction.  I rarely find myself laughing at video game attempts at humour (save for the Sam n' Max series, Day of the Tentacle, and some of the Space Quest games), but I find myself howling with laughter at this game's script.  Alot of it has to do with the delivery from the voice actors; good voice acting is a well needed change from previous arcade entries in the series.  Not to mention the gameplay is a blast.

House of the Dead: Overkill is pretty awesome. Love the game so much. As for Wii Fit I essentially bought it for the balance board but I should probably start using it anyways. Not overweight but hey why not.

I also am very grateful for Wii Fit. I am 20 years old and a little on the scrawny side (my BMI is just in the underweight range according to Wii Fit) and it has helped me a lot in my aim to gain a bit of muscle. I have started eating 3 meals a day again, which I often missed out on, and this is because i observed that when I skipped a meal I lost weight. I have mostly been focussing on Balance games, and have dramatically improved my balance.

well, it's not technically balance that improves when you play Wii Fit, it's the strength of the muscles in your feet and ankles

Im 4lbs lighter now (in 2 weeks and gained back some flexibility on my right leg)

 Personally I do not put too much stock in the BMI rating within Wii Fit, or otherwise.  It does not take into account muscle density for example.  I've always had really muscular legs and shoulders, and now at 185 lbs, I am pretty much at my ideal weight.  According to the BMI however,  I am just at the cusp of being overweight.  I personally am not truly overweight until I hit 210 lbs though (according to the doc).

Cheers Jimmy, I do know not to take BMI as the be all and end all, and I'm not trying to gain heaps of weight, but I would definately prefer to put on a bit of muscle

When I was a teenager, I wanted to increase my muscle mass and found this routine pretty successful:

 Hi Protein breakfasts might be the best way.  When I was a teenager I helped to build my muscle mass by having higher protein breakfasts: Get up earlier in the morning to prepare some eggs, have a couple slices of toast (whole/multigrain) with peanut butter, and a bowl of rolled oats (oatmeal).  If you have weights, you should do reps at very high weights, without straining yourself of course, until your muscle group you are working is exhausted.  This will only take 5-10 repetitions.  Repeat a few reps if you can.

Also try to have some tuna or salmon 30-60 minutes before lifting weights, as they are very high in protein and easier to digest than meats such as chicken or beef.

Just some suggestions for you

My mum's been borrowing the Wii, and I actually miss Wii Fit. It does a good job of getting you some exercise, especially if you don't really do anything else (I fence weekends, but workdays I didn't use to do anything for the last 7-8 years).

Well, that'll be one more Wii sold for the elderly in a couple of days cause I want mine back.

Thanks, I'm vegetarian, which makes putting on muscle harder, but I shall try all the other suggestions

Then I guess you are stuck with tofu and peanut butter for protein
