Hey! Give this a shot, it is basically a 100% for sure thing as it boosts your metabolism. Before breakfast (this is the key) go for a 30 minute brisk walk or 30 minute light - moderate jog atleast 4 times a week. You pick the days you go. You should definately mix things up a bit. As great as the bike is, try some other exercises off the bike. You could even work in some weight training. Doesn't have to be anything extreme but a couple reps of curls, squats, etc. and that'll also help you boost your metabolism real nice. And of course, watching your diet. Here's a lil bit of what I do...

Stretch

30 min light - moderate jog in the morning (11am or whenever I get up in the afternoon) and then I strech again and have some breakfast. So Good Vanilla or Fat Free with some Vector Cereal and maybe an Apple or Banana.

Rest or Take a 30-45 minute nap.

Stretch

Go for a nice ride, nothign too hard just something to get the legs moving nice. So maybe 1hr or more of riding.

Stretch

Later in the night I'll do 60 sit ups, 60 push ups, 30 supermans and if it's a weight training night 3 reps of 20 for curls with 20lb weight and 30 dips in between reps.

I know this isn't very detailed to read right now but my head hurts and I'm feelin' like crap. I hate being sick. Anyways, it was just a little sample of what other things you can try working into your daily routines.
