Use a real bike instead of a static exercise bike the miles pass quicker.
Seeing as people are giving proper info in here (I'm still not sure if it's a troll?) I'll throw some in. While a real bike can give the impression of doing more, I can guarantee you that you can burn more on an exercise bike. I used to do 45 mins on a bike when I went the gym, doing 2 mins at a setting that will have no relevance, then 30 seconds on the hardest setting pushing for my life. Standard interval training I know, but you couldn't do that on a real bike, because unless you so happen to live in a place that has 2 minutes of slight incline then 30 seconds of mountain you're going to struggle to recreate a good interval training environment.
Here's a little plan for the OP, gym, 5-10 minute warm up on treadmill, just walk, not even at pace, just to get your blood flowing.
Then go on a bike, 30 minutes to start with, you want a setting that you're comfortable with, let's say this was 10/20, do that for 5 minutes, then slowly increase it to something where you're struggling to continue over the next few minutes. You want something that you can do for a short while, but that is tiring. For the rest of the 30 mins, you want to be at 10/20 for 2 mins, then burst for around 30 seconds (Less if that's too much) at the setting you can just about cope with, say 15/20 or so.
Next is the rower, I hate rowers, they crush me, but still, that's the whole idea. You want to set a distance for rowing, or I feel that works better for me, I'd say 1km would be good to start with, this time you're bursting distance, try to do 150m gently, then 50m bursts. It should take you long, but it takes more out of you, and there's more to come so this isn't meant to be even more intense cardio.
Next is weights, there's nothing better than losing weight to find muscle underneath already. This is completely your choice, if you want strength it'll have to be free weights, I can't help you much with what you can lift and how to lift, check out YouTube or just ask someone in the gym, big lifters are some of the most helpful guys ever. If you want to use machines, you won't necessarily get the strength, but you can still get a cut/ripped look, and they're much easier to use, I used to just do every machine in the gym I went to and do free weights at home.
Diet is obviously a massive factor as well, portion control is a big deal, your body doesn't realise it's full until 30 mins after it is, so if you ever feel full while you're eating, you have seriously over eaten. Eat before the gym and after the gym, small carb load before you go, then a bigger carb load and protein after the gym. If you want to build muscle this will work, but it's not the most efficient, it's more about turning you into an overall cardio beast.
