How much is too much?

Too much for what? What are your goals?

The exercise you need to lose weight is a balance between calories in and calories expended. It will be different for everyone and even completely sedentary people can lose weight if they monitor their calories carefully enough.

Exercise to feel better and be stronger.

I have lost 89 pounds so far. I am exercising less than you. If time is an issue, you may consider a HIIT routine that expends more calories in a shorter time.

So vague.

Push yourself to do more when your current routine gets boring. Doing more doesn't necessarily mean more time. For instance, I am now running 3KM in my thirty minutes instead of walking. Or you could put your treadmill on an incline. Or start a C25K routine.

The treadmill tells you how many calories you burned while working out. I've been doing it for three months now and I really pushed my self to get to 300, I don't know if I should push my self to more.

I haven't really exercised or lost weight before so I apologise if my knowledge isn't perfect.

It helps to view diet and fitness as working together in congruence...but mutually exclusive. You don't have to burn anything with exercise...I wouldn't recommend it, but you can lose weight with zero exercise whatsoever. Even without exercise, your body requires XXXX amount of energy (calories) per day...for most people who aren't athletes or exercise freaks, most of your energy requirements are simply existing and then performing your daily hum drum.

Exercise is beneficial in that it does increase your body's energy expenditure...thus your maintenance level of energy increases and so does the amount of calories you can eat to lose weight. It's a nice bi-product of fitness, but you should participate in your fitness for the sake of fitness...it will be far more rewarding and you are much more likely to stick with a fitness regimen for which you have goals that are independent of just burning calories.

If you're using MFP correctly, your calorie goal is one that includes your weight loss deficit per your stats and stated goals...when you exercise you're actually supposed to eat more because that activity isn't accounted for in your activity level (or shouldn't be if you're following the MFP method)...it is extra activity that needs fueling. The more intense and vigorous your exercise regimen, the more important it is to learn to properly fuel that activity and being able to strike a balance between that and weight loss goals...properly fueling exercise activity is essential to recovery and fitness gains.
